Introduction to the 3ware  
Command Line Interface  
The 3ware SATA RAID Controller Command Line Interface (CLI) for Linux,  
Windows, and FreeBSD is provided to manage 7000, 8000, and 9000-series  
3ware ATA and Serial ATA RAID controllers. Multiple 3ware RAID  
controllers can be managed using the CLI via a command line or script.  
Note: Some CLI commands are supported only for particular models of 3ware  
RAID controllers. Wherever possible, commands are labeled to indicate when they  
are supported for only a subset of controllers. For example, commands that apply  
only to 3ware 9000 series controllers are labeled as such and are not supported for  
3ware 7000/8000 controllers. Within the 9000 series, some commands apply to  
only to models 9550SX, 9590SE, and 9650SE and not to 9500S, and are so  
labeled. A few commands apply only to models 9500S, and are labeled as such.  
Important!  
For all of the functions of the 3ware CLI to work properly, you must have the proper  
CLI, firmware, and driver versions installed. Check http://www.3ware.com for the  
latest versions and upgrade instructions.  
This chapter includes the following sections:  
Features of the CLI  
3ware CLI is a command line interface for managing 3ware RAID  
Controllers. It provides controller, logical unit, drive, enclosure, and BBU  
(Battery Backup Unit) management. It can be used in both interactive and  
batch mode, providing higher level API (application programming interface)  
functionalities.

Supported Operating Systems  
You can use the CLI to view unit status and version information and perform  
maintenance functions such as adding or removing drives. 3ware CLI also  
includes advanced features for creating and deleting RAID units online.  
For a summary of what you can do using the CLI, see “Common Tasks  
Supported Operating Systems  
The 3ware CLI is supported under the following operating systems:  
Windows®. Windows 2000, Windows XP, and Windows Server 2003,  
both 32-bit and 64-bit.  
Linux®. Redhat, SuSE, both 32-bit and 64-bit.  
FreeBSD®, both 32-bit and 64-bit.  
For specific versions of Linux and FreeBSD that are supported for the 3ware  
CLI, see the Release Notes.  
Terminology  
This document uses the following terminology:  
Logical Units. Usually shortened to “units.” These are block devices  
presented to the operating system. A logical unit can be a one-tier, two-tier, or  
three-tier arrangement. JBOD, Spare, and Single logical units are examples of  
one-tier units. RAID 1 and RAID 5 are examples of two-tier units and as such  
will have sub-units. RAID 10 and RAID 50 are examples of three-tier units  
and as such will have sub-sub-units.  
Port. A controller has one or many ports (typically 4, 8, 12, 16). Each port can  
be attached to a single disk drive. On a controller such as the 9590SE-4ME,  
with a multilane serial port connector, one connector supports four ports.  
For additional information about 3ware controller concepts and terminology,  
see the user guide that came with your 3ware RAID controller or the user  
guide portions of the 3ware HTML Bookshelf.

Chapter 1. Introduction to the 3ware Command Line Interface  
Installing the 3ware CLI  
Warning!  
If you are using 3DM, as opposed to 3DM2, AMCC does not recommend installing  
both 3DM and CLI on the same system. Conflicts may occur. For example, if both  
are installed, alarms will be captured only by 3DM. You should use either CLI or  
3DM to manage your 3ware RAID controllers.  
This is not an issue for 3DM2. It can be installed with CLI.  
(3DM was an earlier version of the software, which worked with 7/8000 model  
3ware controllers. 3DM 2 works with the 9000-series.)  
Installing the 3ware CLI on Windows  
3ware CLI can be installed or run directly from the 3ware software CD, or the  
latest version can be downloaded from the 3ware web site,  
http://www.3ware.com. Online manual pages are also available in nroff and  
html formats. These are located in /packages/cli/tw_cli.8.htmlor  
tw_cli.8.nroff.  
To install 3ware CLI on Windows  
Copy the file tw_cli.exeto the directory from which you want to run the  
program.  
CLI is located on the 3ware CD in the directory \packages\cli\windows  
Note: CLI comes in both 32-bit and 64-bit versions. Be sure to copy the correct  
version for the version of the operating system you are using.  
Permissions Required to Run CLI  
To run CLI, you can be logged onto Windows with one of the following sets  
of permissions:  
Administrator  
User with administrator rights  
Domain administrator  
Domain user with Domain Admin or Administrator membership  
Without the correct privileges, CLI will prompt and then exit when the  
application is executed.

Installing the 3ware CLI  
If you are uncertain whether you have the correct permissions, contact your  
network administrator.  
To start CLI, do one of the following:  
Start the 3ware CD and at the 3ware Escalade menu, click Run CLI.  
Or, open a console window, change to the directory where tw_cli is  
located, and at the command prompt, enter  
tw_cli  
OR, double-click the CLI icon in a folder.  
The CLI prompt is displayed in a DOS console window.  
Installing the 3ware CLI on Linux and FreeBSD  
3ware CLI can be installed or run directly from the 3ware software CD, or the  
latest version can be downloaded from the 3ware web site,  
To install the 3ware CLI, copy tw_cli to the directory from which you want to  
run the program. CLI is located on the 3ware CD in /packages/cli/freebsd  
or /packages/cli/linux.  
Online manual pages are also available in nroff and html formats. These are  
located in /packages/cli/tw_cli.8.htmlor tw_cli.8.nroff.  
You will need to be root or have root privileges to install the CLI to  
/usr/sbinand to run the CLI.  
Filename: tw_cli  
To install the CLI to a different location, change /usr/sbin/to the desired  
location.  
Notes:  
The installation location needs to be in the environment path for root to execute the  
CLI without using complete paths (i.e., if installed to /usr/sbin/, you can type tw_cli  
on the command line, otherwise you will have to type the complete path:  
/home/user/tw_cli  
The 3ware CLI comes in both 32-bit and 64-bit versions. Be sure to copy the correct  
version for the version of the operating system you are using.

Chapter 1. Introduction to the 3ware Command Line Interface  
Working with 3ware CLI  
You can work with the 3ware CLI in different ways:  
Interactively, entering commands at the main prompt  
As a series of single commands  
By creating a script—an input file with multiple commands  
The next few topics shows examples of these different methods.  
Examples shown in the CLI Syntax Reference chapter reflect the interactive  
method.  
Using the command interface interactively  
You can use 3ware CLI interactively, entering commands at the main prompt  
and observing the results on the screen.  
To use the CLI interactively  
1
Enter the following command:  
# tw_cli  
The main prompt is displayed, indicating that the program is awaiting a  
command.  
//localhost>  
2
At the CLI prompt, you can enter commands to show or act on 3ware  
controllers, units, and drives.  
For example,  
//localhost> show  
displays all controllers in the system and shows details about them, like  
this:

Working with 3ware CLI  
Using a single command with output  
You can use 3ware CLI with line arguments, processing a single command at  
a time. To do so, simply enter the command and the arguments.  
Single commands can be useful when you want to perform a task such as  
redirecting the output of the command to a file. It also allows you to use the  
command line history to eliminate some typing.  
Syntax  
tw_cli <command_line_arguments>  
Example  
tw_cli /c0 show diag > /tmp/3w_diag.out  
Using an input file to execute a script  
You can operate 3ware CLI scripts by executing a file. The file is a text file  
containing a list of CLI commands which you have entered in advance. Each  
command must be on a separate line.  
Syntax  
tw_cli -f <filename>  
Where <filename>is the name of the text file you want to execute.  
Example  
tw_cli -f clicommand.txt  
This example executes the file clicommand.txt, and runs the CLI commands  
included in that file.  
Scripting example  
Following is a scripting example using a text file called config_unit.txt,  
containing three commands. This example sets up a 12-port controller with  
two units: one with the first 2 drives mirrored, and another with the remaining  
drives in a RAID 5 array. It then prints the configurations for verification. The  
commands included in the script file are:  
/c0 add type=raid1 disk=0-1  
/c0 add type=raid5 disk=2-11  
/c0 show  
To run the script, enter:  
tw_cli -f config_unit.txt

Chapter 1. Introduction to the 3ware Command Line Interface  
Outputting the CLI to a Text File  
You can have the output of the 3ware CLI, including errors, sent to a text file  
by adding 2>&1 to the end of the line. This could be useful, for example, if  
you want to email the output to AMCC Technical Support.  
Examples  
tw_cli /c2/p0 show >> controller2port0info.txt 2>&1  
or  
tw_cli /c0 show diag >> Logfile.txt 2>&1  
Conventions  
The following conventions are used through this guide:  
In text, monospace fontis used for code and for things you type.  
In descriptions and explanations of commands, a bold font indicates the  
name of commands and parameters, for example, /c0/p0 show all.  
In commands, an italic font indicates items that are variable, but that you  
must specify, such as a controller ID, or a unit ID, for example, /c0/p0  
show attribute, and /cx/px show all  
In commands, brackets around an item indicates that it is optional.  
In commands, ellipses (...) indicate that more than one parameter at a time  
can be included, for example, /c0/p0 show attribute [attribute ...], or that  
there is a range between two values from which you can pick a value, for  
example, /cx set carvesize=[1024...2048].  
In commands, a vertical bar (|) indicates an 'or' situation where the user  
has a choice between more than one attribute, but only one can be  
specified.  
Example: In the command to rescan all ports and reconstitute all units, the  
syntax appears as /cx rescan [noscan]. The brackets [ ] indicate that you may  
omit the noscan parameter, so that the operation will be reported to the  
operating system.

Understanding RAID Levels and Concepts  
Understanding RAID Levels and Concepts  
3ware RAID controllers use RAID (Redundant Array of Inexpensive Disks)  
to increase your storage system’s performance and provide fault tolerance  
(protection against data loss).  
This section organizes information about RAID concepts and configuration  
levels into the following topics:  
“RAID Concepts” on page 1  
“Available RAID Configurations” on page 1  
“Determining What RAID Level to Use” on page 1  
RAID Concepts  
The following concepts are important to understand when working with a  
RAID controller:  
Arrays and Units. In the storage industry, the term “array” is used to  
describe two or more disk drives that appear to the operating system as a  
single unit. When working with a 3ware RAID controller, “unit” is the  
term used to refer to an array of disks that is configured and managed  
through the 3ware software. Single-disk units can also be configured in  
the 3ware software.  
Mirroring. Mirrored arrays (RAID 1) write data to paired drives  
simultaneously. If one drive fails, the data is preserved on the paired  
drive. Mirroring provides data protection through redundancy. In  
addition, mirroring using a 3ware RAID controller provides improved  
performance because 3ware’s TwinStor technology reads from both  
drives simultaneously.  
Striping. Striping across disks allows data to be written and accessed on  
more than one drive, at the same time. Striping combines each drive’s  
capacity into one large volume. Striped disk arrays (RAID 0) achieve  
highest transfer rates and performance at the expense of fault tolerance.  
Distributed Parity. Parity works in combination with striping on RAID 5,  
RAID 6, and RAID 50. Parity information is written to each of the striped  
drives, in rotation. Should a failure occur, the data on the failed drive can  
be reconstructed from the data on the other drives.  
Hot Swap. The process of exchanging a drive without having to shut  
down the system. This is useful when you need to exchange a defective  
drive in a redundant array.

Chapter 1. Introduction to the 3ware Command Line Interface  
Array Roaming. The process of removing a unit from a controller and  
putting it back later, either on the same controller, or a different one, and  
having it recognized as a unit. The disks may be attached to different ports  
than they were originally attached to, without harm to the data.  
For definitions of other terms used throughout the documentation, see the  
“Glossary”.  
Available RAID Configurations  
RAID is a method of combining several hard drives into one unit. It offers  
fault tolerance and higher throughput levels than a single hard drive or group  
of independent hard drives. RAID levels 0, 1, 10 and 5 are the most popular.  
AMCC's 3ware controllers support RAID 0, 1, 5, 6, 10, 50, JBOD and Single  
Disk. The information below provides a more in-depth explanation of the  
different RAID levels.  
For how to configure RAID units, see “Configuring a New Unit” on page 96.  
RAID 0  
RAID 0 provides improved performance, but no fault tolerance. Since the  
data is striped across more than one disk, RAID 0 disk arrays achieve high  
transfer rates because they can read and write data on more than one drive  
simultaneously. The stripe size is configurable during unit creation. RAID 0  
requires a minimum of two drives.  
When drives are configured in a striped disk array (see Figure ?), large files  
are distributed across the multiple disks using RAID 0 techniques.  
Striped disk arrays give exceptional performance, particularly for data  
intensive applications such as video editing, computer-aided design and  
geographical information systems.  
RAID 0 arrays are not fault tolerant. The loss of any drive results in the loss of  
all the data in that array, and can even cause a system hang, depending on  
your operating system. RAID 0 arrays are not recommended for high  
availability systems unless additional precautions are taken to prevent system  
hangs and data loss.

Understanding RAID Levels and Concepts  
RAID 1  
RAID 1 provides fault tolerance and a speed advantage over non-RAID disks.  
RAID 1 is also known as a mirrored array. Mirroring is done on pairs of  
drives. Mirrored disk arrays write the same data to two different drives using  
RAID 1 algorithms (see Figure ?). This gives your system fault tolerance by  
preserving the data on one drive if the other drive fails. Fault tolerance is a  
basic requirement for critical systems like web and database servers.  
3ware uses a patented technology, TwinStor®, on RAID 1 arrays for  
improved performance during sequential read operations. With TwinStor  
technology, read performance is twice the speed of a single drive during  
sequential read operation.  
The adaptive algorithms in TwinStor technology boost performance by  
distinguishing between random and sequential read requests. For the  
sequential requests generated when accessing large files, both drives are used,  
with the heads simultaneously reading alternating sections of the file. For the  
smaller random transactions, the data is read from a single optimal drive head.  
Figure 2. RAID 1 Configuration Example  
RAID 5  
RAID 5 provides performance, fault tolerance, high capacity, and storage  
efficiency. It requires a minimum of three drives and combines striping data  
with parity (exclusive OR) to restore data in case of a drive failure.  
Performance and efficiency increase as the number of drives in a unit  
increases.  
Parity information is distributed across all of the drives in a unit rather than  
being concentrated on a single disk (see Figure ?). This avoids throughput  
loss due to contention for the parity drive.  
RAID 5 is able to tolerate 1 drive failure in the unit.

Chapter 1. Introduction to the 3ware Command Line Interface  
Figure 3. RAID 5 Configuration Example  
RAID 6  
RAID 6 requires a 3ware 9650SE RAID controller.  
RAID 6 provides greater redundancy and fault tolerance than RAID 5. It is  
similar to RAID 5, but has two blocks of parity information (P+Q) distributed  
across all the drives of a unit, instead of the single block of RAID 5.  
Due to the two parities, a RAID 6 unit can tolerate two hard drives failing  
simultaneously. This also means that a RAID 6 unit may be in two different  
states at the same time. For example, one sub-unit can be degraded, while  
another may be rebuilding, or one sub-unit may be initializing, while another  
is verifying.  
RAID 6 requires a minimum of five drives. Performance and storage  
efficiency also increase as the number of drives increase.

Understanding RAID Levels and Concepts  
Figure 4. RAID 6 Configuration Example  
RAID 10  
RAID 10 is a combination of striped and mirrored arrays for fault tolerance  
and high performance.  
When drives are configured as a striped mirrored array, the disks are  
configured using both RAID 0 and RAID 1 techniques, thus the name RAID  
10 (see Figure ?). A minimum of four drives are required to use this  
technique. The first two drives are mirrored as a fault tolerant array using  
RAID 1. The third and fourth drives are mirrored as a second fault tolerant  
array using RAID 1. The two mirrored arrays are then grouped as a striped  
RAID 0 array using a two tier structure. Higher data transfer rates are  
achieved by leveraging TwinStor and striping the arrays.  
In addition, RAID 10 arrays offer a higher degree of fault tolerance than  
RAID 1 and RAID 5, since the array can sustain multiple drive failures  
without data loss. For example, in a twelve-drive RAID 10 array, up to six  
drives can fail (half of each mirrored pair) and the array will continue to  
function. Please note that if both halves of a mirrored pair in the RAID 10  
array fail, then all of the data will be lost.

Chapter 1. Introduction to the 3ware Command Line Interface  
Figure 5. RAID 10 Configuration Example  
RAID 50  
RAID 50 is a combination of RAID 5 with RAID 0. This array type provides  
fault tolerance and high performance. RAID 50 requires a minimum of six  
drives.  
Several combinations are available with RAID 50. For example, on a 12-port  
controller, you can have a grouping of 3, 4, or 6 drives. A grouping of 3 means  
that the RAID 5 arrays used have 3 disks each; four of these 3-drive RAID 5  
arrays are striped together to form the 12-drive RAID 50 array. On a 16-port  
controller, you can have a grouping of 4 or 8 drives.  
In addition, RAID 50 arrays offer a higher degree of fault tolerance than  
RAID 1 and RAID 5, since the array can sustain multiple drive failures  
without data loss. For example, in a twelve-drive RAID 50 array, up to one  
drive in each RAID 5 set can fail and the array will continue to function.  
Please note that if two or more drives in a RAID 5 set fail, then all of the data  
will be lost.

Figure 6. RAID 50 Configuration Example  
Single Disk  
A single drive can be configured as a unit through 3ware software. (3BM,  
3DM 2, or CLI). Like disks in other RAID configurations, single disks  
contain 3ware Disk Control Block (DCB) information and are seen by the OS  
as available units.  
Single drives are not fault tolerant and therefore not recommended for high  
availability systems unless additional precautions are taken to prevent system  
hangs and data loss.  
JBOD  
A JBOD (acronym for “Just a Bunch of Disks”) is an unconfigured disk  
attached to your 3ware RAID controller. JBOD configuration is no longer  
supported in the 3ware 9000 series. AMCC recommends that you use Single  
Disk as a replacement for JBOD, to take advantage of advanced features such  
as caching, OCE, and RLM.  
JBOD units are not fault tolerant and therefore not recommended for high  
availability systems unless additional precautions are taken to prevent system  
hangs and data loss.

Hot Spare  
A hot spare is a single drive, available online, so that a redundant unit can be  
automatically rebuilt in case of drive failure.  
Determining What RAID Level to Use  
Your choice of which type of RAID unit (array) to create will depend on your  
needs. You may wish to maximize speed of access, total amount of storage, or  
redundant protection of data. Each type of RAID unit offers a different blend  
of these characteristics.  
The following table provides a brief summary of RAID type characteristics.  
Table 2: RAID Configuration Types  
RAID Type  
Description  
RAID 0  
RAID 1  
Provides performance, but no fault tolerance.  
Provides fault tolerance and a read speed advantage over non-  
RAID disks.  
RAID 5  
RAID 6  
This type of unit provides performance, fault tolerance, and high  
storage efficiency. RAID 5 units can tolerate one drive failing  
before losing data.  
Provides very high fault tolerance with the ability to protect  
against two consecutive drive failures. Performance and  
efficiency increase with higher numbers of drives.  
RAID 10  
A combination of striped and mirrored units for fault tolerance  
and high performance.  
RAID 50  
A combination of RAID 5 and RAID 0. It provides high fault  
tolerance and performance.  
Single Disk  
Not a RAID type, but supported as a configuration.  
Provides for maximum disk capacity with no redundancy.  
You can create one or more units, depending on the number of drives you  
have installed.

Using Drive Capacity Efficiently  
To make the most efficient use of drive capacity, it is advisable to use drives  
of the same capacity. This is because the capacity of each drive is limited to  
the capacity of the smallest drive in the unit.  
The total array capacity is defined as follows:  
Table 4: Drive Capacity  
RAID Level  
Capacity  
Single Disk  
RAID 0  
Capacity of the drive  
(number of drives) X (capacity of the smallest drive)  
Capacity of the smallest drive  
RAID 1  
RAID 5  
(number of drives - 1) X (capacity of the smallest drive)  
Storage efficiency increases with the number of disks:  
storage efficiency = (number of drives -1)/(number of drives)  
RAID 6  
(number of drives - 2) x (capacity of the smallest drive)  
(number of drives / 2) X (capacity of smallest drive)  
RAID 10

Chapter 1. Introduction to the 3ware Command Line Interface  
Table 4: Drive Capacity  
RAID Level  
Capacity  
RAID 50  
(number of drives - number of groups of drives) X (capacity of the  
smallest drive)  
Through drive coercion, the capacity used for each drive is rounded down so  
that drives from differing manufacturers are more likely to be able to be used  
as spares for each other. The capacity used for each drive is rounded down to  
the nearest GB for drives under 45 GB (45,000,000,000 bytes), and rounded  
down to the nearest 5 GB for drives over 45 GB. For example, a 44.3 GB  
drive will be rounded down to 44 GB, and a 123 GB drive will be rounded  
down to 120 GB. For more information, see the discussion of drive coercion  
under “Creating a Hot Spare” on page 108.  
Support for Over 2 Terabytes  
Windows 2000, Windows XP (32-bit), Linux 2.4, and FreeBSD 4.x, do not  
currently recognize unit capacity in excess of 2 TB.  
If the combined capacity of the drives to be connected to a unit exceeds 2  
Terabytes (TB), you can enable auto-carving when you configure your units.  
Auto-carving divides the available unit capacity into multiple chunks of 2 TB  
or smaller that can be addressed by the operating systems as separate  
volumes. The carve size is adjustable from 1024 MB to 2048 MB (default)  
prior to unit creation.  
If a unit over 2 TB was created prior to enabling the auto-carve option, its  
capacity visible to the operating system will still be 2TB; no additional  
capacity will be registered. To change this, the unit has to be recreated.  
For more information, see “Using Auto-Carving for Multi LUN Support” on  
page 91.

Syntax Overview  
The command syntax uses the general form:  
Object Command Attributes  
Objects are shell commands, controllers, units, ports (drives), BBUs (battery  
backup units), and enclosures.  
Commands can either select (show, get, present, read) attributes or alter (add,  
change, set, write) attributes.

Chapter 2. CLI Syntax Reference  
Attributes are either Boolean Attributes or Name-Value Attributes.  
The value of a boolean attribute is deduced by presence or lack of—that  
is, the attribute is either specified, or not. For example, the command  
show alarms by default lists alarms with the most recent alarm first. If  
you include the attribute reverse, as in the command show alarms  
reverse, alarms are listed in reverse order.  
The value of name-value attributes are expressed in the format  
attribute=value.  
Example: When adding (creating) a unit to the controller with the following  
command string,  
/c1 add type=raid1 disk=0-1  
c1is the object, addis the command, type(for type of array) is an attribute  
with raid1as the value of the attribute, and diskis another attribute with  
0-1as the value (ports 0 through 1).  
Information about commands is organized by the object on which the  
commands act:  
Shell Object Commands. Shell object commands set the focus or provide  
information (such as alarms, diagnostics, rebuild schedules, and so forth)  
about all controllers in the system. For details, see “Shell Object Commands”  
Controller Object Commands. Controller object commands provide  
information and perform actions related to a specific controller. For example,  
you use controller object commands for such tasks as seeing alarms specific  
to a controller, creating schedules during which background tasks are run, and  
setting policies for the controller. You also use the controller object command  
/cx add type to create RAID arrays. For details, see “Controller Object  
Unit Object Commands. Unit object commands provide information and  
perform actions related to a specific unit on a specific controller. For example,  
you use unit object commands for such tasks as seeing the rebuild, verify, or  
initialize status of a unit, starting, stopping, and resuming verifies, starting  
and stopping rebuilds, and setting policies for the unit. You also use the  
controller object command /cx/ux migrate to change the configuration of a  
RAID array. For details, see “Unit Object Commands” on page 59.  
Port Object Commands. Port object commands provide information and  
perform actions related to a drive on a specific port. For example, you use port  
object commands for such tasks as seeing the status, model, or serial number  
of the drive. For details, see “Port Object Commands” on page 77.  
BBU Object Commands. BBU object commands provide information and  
perform actions related to a Battery Backup Unit on a specific controller. For

Shell Object Commands  
Enclosure Object Commands. Enclosure object commands provide  
information and perform actions related to a particular enclosure. For  
example, you can use enclosure object commands to see information about an  
enclosure and its elements (slots, fan, and temperature sensor elements).  
Help Commands. Help commands allow you to display help information for  
all commands and attributes. For details, see “Help Commands” on page 91.  
Shell Object Commands  
Shell object commands are either applicable to all the controllers in the  
system (such as show, rescan, flush, commit), or redirect the focused object.  
Syntax

show [attribute [modifier]]  
ver

rescan

commit  
update fw=filename_with_path [force]  
focus Object  
The focus command is active in interactive mode only and is provided to  
reduce typing.  
The focus command will set the specified object in focus and change the  
prompt to reflect this. This allows you to enter a command that applies to the  
focus, instead of having to type the entire object name each time.  
For example, where normally you might type:  
//hostname/c0/u0 show  
if you set the focus to //hostname/c0/u0, the prompt changes to reflect that,  
and you only have to type show. The concept is similar to being in a particular  
location in a file system and requesting a listing of the current directory.  
object can have the following forms:  
//hostname/cx/uxspecifies the fully qualified URI (Universal Resource  
Identifier) of an object on host hostname, controller cx, unit ux.

Chapter 2. CLI Syntax Reference  
//hostnamespecifies the root of host hostname.  
..specifies one level up (the parent object).  
/ specifies the root at the current focused hostname.  
./object specifies the next level of the object.  
/c0/bbu specifies a relative path with respect to the current focused  
hostname.  
Example:  
//localhost> focus /c0/u0  
//localhost/c0/u0>  
//localhost/c0/u0> focus..  
//localhost/c0>  
//localhost> focus u0  
//localhost/c0/u0>  
//localhost/c0> focus /  
//localhost>  
The focus command is available by default. You can disable focus by setting  
TW_CLI_INPUT_STYLE to old. (See “Return Code” on page 96.)  
show  
This command shows a general summary of all detected controllers.  
Note that the device drivers for the appropriate operating system should be  
loaded for the list to show all controllers. The intention is to provide a global  
view of the environment.  
Example:  
Typical output of the Show command looks like the following:  
//localhost> show

(Not Optimal) state, RRate (Rebuild Rate) of 2, VRate (Verify Rate) of 5,  
BBU of '-' (Not Applicable). Not Optimal refers to any state except OK and  
VERIFYING. Other states include VERIFY-PAUSED, INITIALIZING, INIT-  
PAUSED, REBUILDING, REBUILD-PAUSED, DEGRADED,

For a system with an enclosure unit that includes support for an EPCT  
(Enclosure Port Configuration Table), applicable firmware and software, and  
an appropriate controller (9550SX, 9590SE, or 9650SE), a global view of the  
environment also includes summary information about detected enclosures.

This command shows summary information on the specified controller /cx.  
This information is organized into a report containing two to three parts:  
A Unit summary listing all present units  
A Port summary section listing of all ports and disks attached to them.  
A BBU summary section listing, if a BBU is installed on the controller.  
The Unit summary section lists all present unit and specifies their unit  
number, unit type (such as RAID 5), unit status (such as INITIALIZING), %R  
(percent completion of rebuilding), % V/I/M (percent completion of  
verifying, initializing, or migrating), stripe size, size (usable capacity) in  
gigabytes or terabytes, and the auto-verify policy status (on/off)  
Possible unit statuses include OK, RECOVERY, INOPERABLE,  
UNKNOWN, DEGRADED, INITIALIZING, INIT-PAUSED, VERIFYING,  
VERIFY-PAUSED, REBUILDING, REBUILD-PAUSED, MIGRATING, and  
MIGRATE-PAUSED. Definitions of the unit statuses are available in the  
3ware Serial ATA RAID Controller User Guide.  
Note: If an asterisk (*) appears next to the status of a unit, there is an error on one  
of the drives in the unit. This feature provides a diagnostic capability for potential  
problem drives. The error may not be a repeated error, and may be caused by an  
ECC error, SMART failure, or a device error. Rescanning the controller will clear the  
drive error status if the condition no longer exists.  
The Port summary section lists all present ports and specifies the port  
number, disk status, unit affiliation, size (in gigabytes) and blocks (512 bytes),  
and the serial number assigned by the disk vendor.  
The BBU summary lists details about the BBU, if one is installed. It includes  
a few important attributes such as hours left (in which the current BBU can

Controller Object Commands  
/cx show spinup  
This feature only applies to 9000 series controllers.  
This command reports the number of concurrent disks that will spin up when  
the system is powered on, after waiting for the number of seconds specified  
with the set staggercommand.  
Example:  
//localhost> /c0 show spinup  
/c0 Disk Spinup Policy = 1  
/cx show stagger  
This feature only applies to 9000 series controllers.  
This command reports the time delay between each group of spinups at the  
power on.  
Example:  
//localhost> /c0 show stagger  
/c0 Spinup Stagger Time Policy (sec) = 2  
/cx show ondegrade  
This feature only applies to 9500S controllers.  
This command reports the cache policy for degraded units. If the ondegrade  
policy is “Follow Unit Policy,” a unit cache policy stays the same when the  
unit becomes degraded. If the ondegrade policy is off, a unit cache policy will  
be forced to “off” when the unit becomes degraded.  
Example:  
//localhost> /c0 show ondegrade  
/c0 Cache on Degraded Policy = Follow Unit Policy  
/cx show autocarve  
This feature only applies to 9000 series controllers.  
This command reports the Auto-Carve policy. If the policy is on, all newly  
created or migrated units larger than the carvesize will be automatically  
carved into multiples of carvesize volumes plus one remainder volume. Each  
volume can be treated as an individual drive with its own file system. The  
default carvesize is 2TB. For more information see, “/cx show carvesize”,  
below.

Chapter 2. CLI Syntax Reference  
For operating systems that support units larger than 2TB, there is no need to  
set the policy to on unless you want the operating system to have multiple  
smaller volumes.  
If you use a 32-bit operating system, it is recommended that you keep the  
policy on unless you know that your operating system supports disks that are  
larger than 2 TB.  
When the autocarve policy is off, all newly created units will consist of one  
single volume.  
Example:  
//localhost> /c0 show autocarve  
/c0 Auto-Carving Policy = on  
/cx show carvesize  
This feature only applies to 9000 series controllers.  
This command shows the maximum size of the volumes that will be created if  
the autocarve policy is set to on. The carvesize can be set between 1024 GB  
and 2048 GB. Default carvesize is 2048 GB (2 TB). For more information  
Example:  
//localhost> /c0 show carvesize  
/c0 Auto-Carving Size = 2000 GB  
/cx show memory  
This command reports the size of the memory installed on the controller.  
Note: The 9500S controllers ship with 128 MBytes of cache, yet only 112MB  
shows as memory installed. The other 16 MB is reserved for use by the controller.  
Example:  
//localhost> /c0 show memory  
/c0 Memory Installed = 112MB

Controller Object Commands  
/cx show autorebuild  
This feature only applies to 9550SX, 9590SE, and 9650SE model controllers.  
This command shows the Auto-Rebuild policy. If the policy is enabled, the  
firmware will select drives to use for rebuilding a degraded unit using the  
following priority order. For more information, see “/cx set  
1. Smallest usable spare.  
2. Smallest usable unconfigured (available) drive.  
3. Smallest usable failed drive.  
If the policy is disabled, only spare drives will be used for an automatic  
rebuild operation.  
Example:  
//localhost> /c0 show autorebuild  
/c0 Auto-Rebuild Policy = on  
/cx show unitstatus  
This command presents a list of units currently managed by the specified  
controller /cx, and shows their types, capacity, status, and unit policies.  
Possible statuses include: OK, VERIFYING, VERIFY-PAUSED,  
INITIALIZING, INIT-PAUSED, REBUILDING, REBUILD-PAUSED,  
DEGRADED, MIGRATING, MIGRATE-PAUSED, RECOVERY,  
INOPERABLE, and UNKNOWN. (Definitions of the unit statuses are  
available in the 3ware Serial ATA RAID Controller User Guide.)  
Note: If an asterisk (*) appears next to the status of a unit, there is an error on one  
of the drives in the unit. This feature provides a diagnostic capability for potential  
problem drives. The error may not be a repeated error, and may be caused by an  
ECC error, SMART failure, or a device error. Rescanning the controller will clear the  
drive error status if the condition no longer exists.  
Example:  
//localhost> /c2 show unitstatus

[nocache] [autoverify] [noqpolicy][ignoreECC]  
[name=string]  
[storsave=<protect|balance|perform>]  
This command allows you to create a new unit on the specified controller. You  
specify type, disks, and optional stripe size. By default the host operating  
system will be informed of the new block device, write cache will be enabled,  
and a storsave policy of protect will be set. In case of RAID 50, you can also  
specify the layout of the unit by specifying the number of disks per disk group  
with the groupattribute.  
/cx is the controller name, for example /c0, /c1, and so forth.  
type=RaidType specifies the type of RAID unit to be created. Possible unit  
types include raid0, raid1, raid5, raid6 (9650SE only), raid10, raid50, single,  
spare, and JBOD.  
Example: type=raid5  
When a new unit is created, it is automatically assigned a unique serial  
number. In addition, users can assign the unit a name.  
Note: The unit’s serial number cannot be changed.

group=3|4|5|6|7|8 indicates the number of disks per group for a RAID 50  
type. (This attribute can only be used when type=raid50.) Recall that a RAID  
50 is a multi-tier array. At the bottom-most layer, N number of disks per group  
are used to form the RAID 5 layer. These RAID 5 arrays are then integrated  
into a RAID 0. This attribute allows you to specify the number of disks in the  
RAID 5 level. Valid values are 3, 4, 5, 6, 7, and 8.  
Note that a sufficient number of disks are required for a given pattern or disk  
group. For example, given 6 disks, specifying 3 will create two RAID 5  
arrays. With 12 disks, specifying 3 will create four RAID 5 arrays under the  
RAID 0 level. With only 6 disks a grouping of 6 is not allowed, as you would  
basically be creating a RAID 5.  
The default RAID 50 grouping varies, based on number of disks. For 6 and 9  
disks, default grouping is 3. For 8 disks, the default grouping is 4. For 10  
disks, the default grouping is 5, and for 12 disks, the disks can be grouped into  
groups of 3, 4, or 6 drives (the group of 4 drives is set by default as it provides  
the best of net capacity and performance). For 15 disks, the disks can be

Chapter 2. CLI Syntax Reference  
grouped into groups of 3 or 5 drives. For 16 disks, the disks can be grouped  
into groups of 4 or 8 drives.  
noscan attribute instructs CLI not to notify the operating system of the  
creation of the new unit. By default CLI will inform the operating system.  
One application of this feature is to prevent the operating system from  
creating block special devices such as /dev/sdb and /dev/sdc as some  
implementations might create naming fragmentation and a moving target.  
nocache attribute instructs CLI to disable the write cache on the newly  
created unit. Enabling write cache increases write performance at the cost of  
potential data loss in case of sudden power loss (unless a BBU or UPS is  
installed). By default the cache is enabled. To avoid the possibility of data loss  
in the event of a sudden power loss, it is recommended not to set nocache  
unless there is a BBU (battery backup unit) or UPS (uninterruptible power  
supply) installed.  
autoverify attribute enables the autoverify attribute on the unit that is to be  
created. For more details on this feature, see “/cx/ux set autoverify=on|off” on  
page 68. This feature is not supported on model 7000/8000. On model 9000,  
the JBOD autoverify attribute is not persistent (does not survive reboots).  
noqpolicy attribute instructs CLI to disable the qpolicy (drive queuing) on the  
newly created unit. The default is for the qpolicy to be on (in other words,  
noqpolicy is not specified). For a spare unit, specifying noqpolicy has no  
effect and the default remains. If the spare unit becomes a true unit, it would  
adopt the qpolicy of the “new” unit. For JBOD, the qpolicy cannot be set  
during unit creation, and specifying noqpolicy returns an error. For more  
ignoreECC attribute enables the ignoreECC/OverwriteECC attribute on the  
unit that is to be created. For more details on this feature, see “/cx/ux set  
ignoreECC=on|off” on page 69. The following table illustrates the supported  
Model-Unit Types. This table only applies to setting this feature at unit  
creation time. IgnoreECC only applies to redundant units. For the 7/8000  
series, this setting is only applicable during rebuild; it is not applicable  
during creation.

controllers. For more information, see “/cx/ux set  
/cx rescan [noscan]  
This command instructs the controller to rescan all ports and reconstitute all  
units. The controller will update its list of ports (attached disks), and attempts  
to read every DCB (Disk Configuration Block) in order to re-assemble its  
view and awareness of logical units. Any newly found unit(s) or drive(s) will  
be listed.  
noscan is used to not inform the operating system of the unit discovery. The  
default is to inform the operating system.  
Note: If you are adding new drives, add them physically before issuing the rescan  
commands. Hot swap carriers are required unless you first power-down the system  
to prevent system hangs and electrical damage.  
Example:  
//localhost> /c1 rescan  
Rescanning controller /c1 for units and drives ...Done  
Found following unit(s): [/c1/u3]  
Found following drive(s): [/c1/p7, /c1/p8]  
Note: Rescanning does not import non-JBOD on 7000/8000 models.

/cx commit  
This command only applies to the Windows operating system. It commits all  
changes if a faster shutdown method is needed when running certain database  
applications. Linux and FreeBSD file systems do not require this command  
since they have their own ways of notifying the controller to do clean up for  
shut down.  
/cx flush  
This command forces the controller to write all cached data to disk for the  
specified controller.  
/cx update fw=filename_with_path [force]  
This command is only for 9000 series controllers.  
This command allows the downloading of the specified firmware image to the  
corresponding controller.  
Note: Before issuing this command, you must have already obtained the  
firmware image and placed it on your system. You can obtain the firmware  
image from the 3ware website: http:www.3ware.com/downloads.  
fw=filename_with_path attribute allows you to specify the firmware image  
file name along with its absolute path. The new image specified by this  
filename_with_path is checked for compatibility with the current controller,  
current driver, and current application versions. A recommendation is then  
made as to whether an update is needed, and you are asked to confirm whether  
you want to continue. If you confirm that you want to continue, the new  
firmware image is downloaded to the specified controller.  
A reboot is required for the new firmware image to take effect.  
Example:  
//localhost> /c0 update fw=/tmp/prom0006.img  
Warning: We strongly recommend backing up your data before  
updating the firmware. Updating the firmware can render the  
device driver and/or management tools incompatible. It is  
recommended to have a copy of current firmware image for  
rollbacks.

/cx show alarms [reverse]  
Asynchronous events (also referred to as AENs or alarms) are originated by  
firmware and captured by their respective device drivers. These events reflect  
warning, debugging, and/or informative messages for the end user. These  
events are kept in a finite queue inside the kernel, awaiting extraction by user  
space programs such as CLI and/or 3DM.  
The /cx show alarms command displays all available alarms on a given  
controller. The default is to display the most recent alarm or AEN message  
first. The user can also use the [reverse] attribute to display the most recent  
alarm or AEN message last.  
Alarms generated on 7000/8000 controllers do not have dates, so you will see  
a '-' in the Date column. This means that it is not applicable. In addition,  
alarm messages on 7000/8000 controllers contain the severity in the message  
text, so the Severity column also shows a '-'.  
Typical output looks like:  
tw_cli> /c1 show alarms reverse

/cx show diag  
This command extracts controller diagnostics suitable for technical support  
usage. Note that some characters might not be printable or rendered correctly  
(human readable). It is recommended to save the output from this command to  
a file, where it can be communicated to technical support or further studied  
with Linux utilities such as od(1).  
In order to redirect the output you must run the following command from a  
command line, not from within the tw_cli shell.  
tw_cli /c0 show diag > diag.txt  
/cx show rebuild  
9000 series controllers support background tasks and allow you to schedule a  
regular time when they occur.  
Rebuild is one of the supported background tasks. Migrate and initialize are  
other background tasks that follow the same schedule as rebuild. Other  
background tasks for which there are separate schedules are verify and  
selftest. For each background task, up to 7 time periods can be registered,  
known as slots 1 through 7. Each task schedule can be managed by a set of  
commands including add, del, show and set a task. Background task  
schedules have a slot id, start-day-time, duration, and status attributes.  
For details about setting up a schedule for background rebuild tasks, see  
Rebuild activity attempts to (re)synchronize all members of redundant units  
such as RAID-1, RAID-10, RAID-5 and RAID-50. Rebuild can be started  
manually or automatically if a spare has been defined. Scheduled rebuilds will  
take place during the scheduled time slot, if enabled the schedules are  
enabled. For in depth information about rebuild and other background tasks,  
see “About Background Tasks” in the 3ware Serial ATA RAID Controller  
User Guide.  
The show rebuild command displays the current rebuild background task  
schedule as illustrated below.

Controller Object Commands  
A status of “disabled” indicates that the task schedule is disabled. In this case,  
the controller will not use the defined schedule timeslots. If the rebuild  
command is entered manually, rebuilding will start within 10 to 15 minutes. It  
will begin automatically if a rebuild is needed and a proper spare drive is set  
up.  
If the rebuild schedule is enabled while a rebuild process is underway, the  
rebuild will pause until a scheduled time slot.  
Example:  
If a unit is in the initialization state at noon on Wednesday and the rebuild  
schedule shown above is in use (with schedules disabled), you would see the  
following status using the show command:

/cx show verify  
9000 series controllers support background tasks and allow you to schedule a  
regular time when they occur.  
Verify is one of the supported background tasks. Rebuild and selftest are other  
background tasks for which there are separate schedules. Migrate and  
initialize are additional background tasks that follow the same schedule as  
rebuild. For each background task, up to 7 time periods can be registered,  
known as slots 1 through 7. Each task schedule can be managed by a set of  
commands including add, del, show and set a task. Background task  
schedules have a slot id, start-day-time, duration, and status attributes.  
For details about setting up a schedule for background verify tasks, see  
Verify activity verifies all units based on their unit type. Verifying RAID 1  
involves checking that both drives contain the exact data. On RAID 5 and  
RAID 6, the parity information is used to verify data integrity. RAID 10 and  
50 are composite types and follow their respective array types. On 9000  
series, non-redundant units such as RAID 0, JBOD, single, and spare, are also  
verified (by reading and reporting un-readable sectors). If any parity  
mismatches are found, the array will be automatically background initialized.  
(For information about the initialization process, see the user guide that came  
with your 3ware RAID controller.)  
The show verify command displays the current verify background task  
schedule as illustrated below.

A status of “disabled” indicates that the controller will not use the defined  
schedule timeslots and will start verifying immediately (within 10 to 15  
minutes), if the verify command is entered manually, or it will begin  
automatically if the autoverify option is set. Rebuilds, migrations, and  
initializations will take priority over verifies.  
/cx show selftest  
9000 series controllers support background tasks and allow you to schedule a  
regular time when they occur.  
Selftest is one of the supported background tasks. Rebuild and verify are other  
background tasks for which there are separate schedules. Migrate and  
initialize are additional background tasks that follow the same schedule as  
rebuild. For each background task, up to 7 time periods can be registered,  
known as slots 1 through 7. Each task schedule can be managed by a set of  
commands including add, del, show and set a task. Background task  
schedules have a slot id, start-day-time, duration, and status attributes.  
For details about setting up a schedule for background selftest tasks, see  
Selftest activity provides two types of selftests; UDMA (Ultra Direct  
Memory Access) and SMART (Self Monitoring Analysis and Reporting).  
Both self tests are checked once each day by default.  
UDMA self test entails checking the current ATA bus speed (between  
controller and attached disk), which could have been throttled down during  
previous operations and increase the speed for best performance (usually one  
level higher). Possible speeds include 33, 66, 100 and 133 Mhz (at this  
writing). Note that UDMA selftest is not applicable (or required) with SATA  
drives, but is left enabled by default.  
SMART activity instructs the controller to check certain SMART supported  
thresholds by the disk vendor. An AEN is logged to the alarms page if a drive  
reports a SMART failure.

/cx set rebuild=enable|disable|1..5  
This command enables or disables all rebuild background task slots on  
controller /cx and sets the priority of rebuild versus I/O operations. When  
enabled, rebuild tasks will only be run during the time slots scheduled for  
rebuilds. If a rebuild is taking place when the schedule is enabled, it will be  
paused until the next scheduled time.

Chapter 2. CLI Syntax Reference  
The priority of rebuild versus I/O operations is specified with 1..5, where 1 is  
more resources and 5 the least. Setting the value to 1 gives maximum  
processing time to rebuilds rather than I/O. Setting the value to 5 gives  
maximum processing time to I/O rather than rebuilds.  
Enabling and disabling rebuild schedules is only for 9000 models, however  
the rebuild rate (1..5) applies to all controllers.  
7000- and 8000-series controllers have only one setting for Task Rate; it  
applies to both rebuild and verify rates. This rate is not persistent following a  
reboot for 7000- and 8000-series controllers.  
/cx set verify=enable|disable|1..5  
This command enables or disables all verify background task slots on  
controller /cx and (when enabled) sets the priority of verification versus I/O  
operations. When enabled, verify tasks will only be run during the time slots  
scheduled for verifies. If a verify is taking place when the schedule is enabled,  
it will be paused until the next scheduled time.  
The priority of verify versus I/O operations is specified with 1..5, where 1 is  
more resources and 5 the least. Setting this value to 1 implies fastest verify,  
and 5 implies fastest I/O.  
Enabling and disabling verify schedules is only for 9000 models, however the  
verify rate (1..5) applies to all controllers.  
Note: When enabling the verify schedule you must also remember to enable the  
autoverify setting for the units to be verified. For more information see  
/cx set selftest=enable|disable  
[task=UDMA|SMART]  
This command enables or disables all selftest tasks or a particular  
selftest_task (UDMA or SMART).  
Enabling and disabling selftest is only for 9000 models. 7/8000 models have  
the same internal schedule, but it is not viewable or changeable.  
Example:  
//localhost> /c0 selftest=enable task=UDMA  
enables UDMA selftest on controller c0.

Controller Object Commands  
/cx set exportjbod=on|off  
This command allows you to set the JBOD Export Policy to on or off. By  
default, exportjbod is off.  
If the JBOD export policy is off, CLI will not be able to create JBODs. During  
reboot, firmware will not export JBOD units to the operating system.  
The JBOD Export Policy is only supported on 9000-series controllers.  
Previous models did not have such a policy enforcement feature.  
A JBOD is an unconfigured disk attached to your 3ware RAID controller.  
AMCC recommends that you use Single Disk as a replacement for JBOD, to  
take advantage of features such as RAID level migration.  
/cx set ondegrade=cacheoff|follow  
This command is only for 9500S controllers.  
This command allows you to set a controller-based write cache policy. If the  
policy is set to cacheoff and a unit degrades, the firmware will disable the  
write-cache on the degraded unit, regardless of what the unit-based write  
cache policy is. If the policy is set to follow and a unit degrades, firmware will  
follow whatever cache policy has been set for that unit. (For details about the  
/cx set spinup=nn  
This command is only for 9000 series controllers.  
This command allows you to set a controller-based Disk Spinup Policy that  
specifies how many drives can spin up at one time. The value must be a  
positive integer between 1 and the number of disks/ports supported on the  
controller (4, 8, or 12). The default is 1.  
This policy is used to stagger spinups of disks at boot time in order to spread  
the power consumption on the power supply. For example, given a spinup  
policy of 2, the controller will spin up two disks at a time, pause, and then spin  
up another 2 disks. The amount of time to pause can be specified with the  
Spinup Stagger Time Policy (/cx set stagger).  
Not all drives support staggered spinup. If you enable staggered spinup and  
have drives that do not support it, the setting will be ignored.

Chapter 2. CLI Syntax Reference  
/cx set stagger=nn  
This command is only for 9000 series controllers.  
This command allows you to set a controller-based Disk Spinup Stagger Time  
Policy that specifies the delay between spin-ups. The value must be a positive  
integer between 0 to 60 seconds. This policy, in conjunction with Disk Spinup  
Policy, specifies how the controller should spin up disks at boot time. The  
default is 6 seconds.  
/cx set autocarve=on|off  
This command is only for 9000 series controllers.  
This command allows you to set the auto-carve policy to on or off. By default,  
autocarve is off.  
When the auto-carve policy is set to on, any unit larger than the carvesize is  
created or migrated into one or more carvesize volumes and a remaining  
volume. Each volume can then be treated as an individual disk with its own  
file system. The default carvesize is 2 TB.  
This feature is useful for operating systems limited to 2TB file systems.  
For example, using the 2 TB default carvesize, a 3 TB unit will be configured  
into one 2 TB volume and one 1 TB volume. A 5 TB unit will be configured  
into two 2 TB volumes and one 1 TB volume.  
When auto-carve policy is set to off, all new units are created as a single large  
volume. If the operating system can only recognize up to 2 TBs, space over 2  
TB will not be available.  
Example:  
//localhost> /c0 set autocarve=on  
Setting Auto-Carving Policy on /c0 to on ... Done.  
/cx set carvesize=[1024..2048]  
This command is only for 9000 series controllers.  
This command allows you to set the carve size in GB. This feature works  
Example:  
//localhost> /c0 set carvesize=2000  
Setting Auto-Carving Size on /c0 to 2000 GB ... Done.

Controller Object Commands  
/cx set autorebuild=on|off  
This command is only for 9550SX , 9590SE, and 9650SE controllers.  
This command turns the Auto-Rebuild policy on or off. By default,  
autorebuild is on.  
If the policy is on the firmware will select drives to use for rebuilding a  
degraded unit using the following priority order.  
1. Smallest usable spare.  
2. Smallest usable unconfigured (available) drive.  
3. Smallest usable failed drive.  
Note: Failed drives can be drives that have mechanically failed, or they can be  
drives that have been disconnected from the controller long enough for the  
controller to classify them as failed.  
Enabling Auto-Rebuild allows you to add a drive to the controller and have it  
be available for a rebuild as soon as you tell the controller to rescan, without  
having to specify it as a spare. It also means that if you accidentally  
disconnect a drive (causing the controller to see it as a failed drive) and then  
reconnect it, the controller will automatically try to use it again.  
If the policy is off, spares are the only candidates for rebuild operations.  
Example:  
//localhost> /c0 set autorebuild=enable  
Setting Auto-Rebuild Policy on /c0 to enable ... Done.  
/cx set autodetect=on|off disk=<p:-p>|all  
This command is only for 9000 series controllers.  
This command is associated with the staggered spin-up feature when hot-  
swapping drives. When staggered spin-up is enabled (see command /cx set  
spinup and /cx set stagger), during a reset or power on, the controller will spin  
up all detected drives with a delay between each spinup, allowing the spread  
of power consumption on the power supply. When a drive is hot-swapped, (as  
opposed to when it has just been powered on or reset), the default behavior of  
the system is immediate spin-up. This command can change the default  
behavior and set the controller to do a staggered spinup for hot-swapped  
drives.  
Note: The autodetect setting cannot be shown in CLI or displayed in 3DM or 3BM.  
This feature may be added in a future release.

Chapter 2. CLI Syntax Reference  
autodetect=on|off enables or disables automatic detection of drives on the  
controller’s ports for staggered spin-up.  
disk=<p:-p>|all specifies one or many disks (that is, drives or ports). If a port  
is empty (no drive is inserted), this feature is disabled for that port and its port  
number is shown. The example below shows that autodetect has been set to  
off to initiate staggered spin-up during hot-swapping, where port 3 was empty  
and ports 5 and 6 had drives inserted.  
Example:  
//localhost>> /c0 set autodetect=off disk=3:5-6  
Setting Auto-Detect on /c0 to [off] for port [3] and for disk  
[5,6]... Done  
If “disk=all,” then all of the drives or ports for that controller are specified.  
For example:  
//localhost>> /c0 set autodetect=off disk=all  
Setting Auto-Detect on /c2 to [off] for all disks/ports... Done.  
Usage Scenario:  
If you are hot-plugging a large number of drives at the same time and are  
concerned that you might overload the power supply, you might use this  
command as follows:  
1
Issue the command (set autodetect=off) to disable automatic detection of  
the ports for staggered spin-up.  
2
3
4
If the ports are not emply, pull the drives out of the specified ports.  
Insert (or replace) the drives at the ports specified.  
Issue the command (set autodetect=on) to enable auto detect of the ports  
with the newly inserted drives.  
The preceding steps would spin up the newly inserted drives in a staggered  
manner. Please note that the command takes longer for ports that do not have  
drives inserted, since the controller allows time for the empty ports to  
respond.  
/cx start mediascan  
This command applies only to 7000/8000 controllers. For 9000 series  
controllers, use the verify command.  
This command provides media scrubbing for validating the functionality of a  
disk, including bad block detection, remapping, and so forth. The command  
starts a media scan operation on the specified controller /cx.

Unit Object Commands  
Unit Object commands provide information and perform actions related to a  
specific unit, such as /c0/u1 (unit 1 on controller 0). For example, you use  
logical disk object commands for such tasks as seeing the rebuild, verify, or  
initialize status of a unit, starting, stopping, and resuming rebuilds and  
verifies, and setting policies for the unit.

/cx/ux show  
This command shows summary information about the specified unit /cx/ux. If  
the unit consists of sub-units as with the case of RAID-1, RAID-5, RAID-10,  
RAID-50, then each sub-unit is further presented. If the Auto-Carving policy  
was on at the time the unit was created and the unit is over the carve size,  
multiple volumes were created and are displayed at the end of the summary  
information. Similarly, if the unit was created using the 3ware BIOS utility  
3BM and a size was entered in the Boot Volume Size field, multiple volumes  
were created and will be displayed. (Note that a volume created using the  
Boot Volume Size feature does not have to be used as a boot volume.)  
One application of the /cx/ux show command is to see which sub-unit of a  
degraded unit has caused the unit to degrade and which disk within that sub-  
unit is the source of degradation. Another application is to see the source and  
destination units during a migration.

many attributes can be requested. Specifying an invalid attribute will  
terminate the loop. Possible attributes are: initializestatus, name (9000 series),  
qpolicy (9550SX, 9590SE, and 9650SE only), rebuildstatus, serial (9000  
series), status, storsave (9550SX, 9590SE, and 9650SE only), verifystatus,  
volumes (9000 series), autoverify (9000 series), cache, ignoreECC (9000  
series), and identify (9550SX, 9590SE, and 9650SE only).  
/cx/ux show status  
This command reports the status of the specified unit.  
Possible statuses include: OK, VERIFYING, VERIFY-PAUSED,  
INITIALIZING, INIT-PAUSED, REBUILDING, REBUILD-PAUSED,  
DEGRADED, MIGRATING, MIGRATE-PAUSED, RECOVERY,  
INOPERABLE, and UNKNOWN. (Definitions of the unit statuses are  
available in the 3ware Serial ATA RAID Controller User Guide.)  
Example:  
//localhost> /c0/u0 show status  
/c0/u5 status = OK  
/cx/ux show rebuildstatus  
This command reports the rebuildstatus (if any) of the specified unit.  
Example:  
//localhost> /c0/u5 show rebuildstatus  
/c0/u5 is not rebuilding, its current state is OK  
If the unit is in the process of migrating, the command will return the  
following:  
//localhost> /c0/u5 show rebuildstatus  
/c0/u5 is not rebuilding, its current state is MIGRATING  
/cx/ux show verifystatus  
This command reports the verifystatus (if any) of the specified unit.

/cx/ux remove [noscan] [quiet]  
This command allows you to remove (previously called “export”) a unit.  
Removing a unit instructs the firmware to remove the specified unit from its  
poll of managed units, but retains the DCB (Disk Configuration Block)  
metadata. A removed unit can be moved to a different controller.  
noscan is used to not inform the operating system of this change. The default  
is to inform the operating system.  
quiet is used for non-interactive mode. No confirmation is given and the  
command is executed immediately. This is useful for scripting purposes.  
Example of interactive mode:  
//localhost> /c0/u0 remove  
Removing /c0/u0 will take the unit offline.  
Do you want to continue?  
Y|N [N]:  
Note: After the unit is removed through the CLI, the unit can be physically  
removed. Hot swap carriers are required to do this while the system is online.  
Otherwise you must power down the system to prevent system hangs and damage.

Chapter 2. CLI Syntax Reference  
/cx/ux del [noscan] [quiet]  
This command allows you to delete a unit. Deleting a unit not only removes  
the specified unit from the controller's list of managed units, but also destroys  
the DCB (Disk Configuration Block) metadata. After deleting a unit, ports (or  
disks) associated with the unit will be part of the free pool of managed disks.  
Warning: This is a destructive command and should be used with care. All data on  
the specified unit will be lost after executing this command.  
noscan is used to not inform the operating system of this change. The default  
is to inform the operating system.  
quiet is used for non-interactive mode. No confirmation is given and the  
command is executed immediately. This is useful for scripting purposes.  
Example of interactive mode:  
//localhost> /c0/u0 del  
Deleting /c0/u0 will cause the data on the unit to be  
permanently lost.  
Do you want to continue ? Y|N [N]:  
/cx/ux start rebuild disk=p<p:-p...> [ignoreECC]  
This command allows you to rebuild a degraded unit using the specified  
disk=p. Rebuild only applies to redundant arrays such as RAID 1, RAID 5,  
RAID 6, RAID 10, and RAID 50.  
During rebuild, bad sectors on the source disk will cause the rebuild to fail.  
RAID 6 arrays are less susceptible to failing since two copies of the data exist.  
You can allow the operation to continue by using ignoreECC.  
The rebuild process is a background task and will change the state of a unit to  
REBUILDING. Various show commands also show the percent completion as  
rebuilding progresses.  
Note that the disk used to rebuild a unit (specified with disk=p) must be a  
SPARE or a unconfigured disk. You must first remove the degraded drive(s)  
before starting the rebuild. Refer to the command “/cx/px remove [noscan]  
[noscan]” on page 43 to add new drives or to retry the original drive.  
If you are rebuilding a RAID 50, RAID 6, or RAID 10 unit, multiple drives  
can be specified if more than one sub-array is degraded.  
When you issue this command, the specified rebuild will begin if schedules  
are disabled; otherwise it will pause until the next scheduled rebuild. A file  
system check is recommended following rebuild when using the ignoreECC  
option.

When you issue this command, the specified verify will begin if schedules are  
disabled; otherwise it will pause until the next scheduled verify. Verify will  
also pause if a rebuild or initialization is currently in progress.  
/cx/ux pause rebuild  
This command allows you to pause the rebuild operation on the specified unit  
/cx/ux.  
This feature is only supported on the 7000/8000 series controllers. 9000 series  
controllers have an on-board scheduler where rebuild operations can be  
scheduled to take place at specified start and stop times. The /cx/ux pause  
rebuild command is provided to enable 7000/8000 users to achieve similar  
functionality with use of Linux-provided schedulers such as cron(8) or at(1),  
or user-supplied programs.  
/cx/ux resume rebuild  
This command allows you to resume the rebuild operation on the specified  
unit /cx/ux.  
This feature is intended only for 7000/8000 series controllers. 9000 series  
controllers have an on-board scheduler where rebuild operations can be  
scheduled to take place at specified start and stop times. The /cx/ux resume  
rebuild function is provided to enable 7000/8000 users to achieve similar

functionality with use of Linux-provided schedulers such as cron(8) or at(1),  
or user supplied programs.  
/cx/ux stop verify  
This command stops a background verification process on the specified unit  
/cx/ux. Table 9 on page 67 shows the supported matrix as a function of the  
controller model and logical unit type.  
/cx/ux flush  
This command allows you to flush the write cache on the specified unit /ux  
associated with controller /cx. Note that this command does not apply to spare  
unit types.  
/cx/ux set autoverify=on|off  
This feature only applies to 9000 series controllers.  
This command allows you to turn on and off the autoverify operation on a  
specified unit /cx/ux during allocated schedule windows.  
You can use the show verify command to display the existing schedule  
windows. By default, autoverify is off.  
Auto-verify allows the controller to run the verify function once every 24  
hours. If verify schedule windows are set up and enabled, then the controller  
will ony start an automatic verify task during the schedule time slots. If the  
verify takes longer than the schedule window, the verify process will be  
paused and restarted during the next verify schedule window. For additional  
/cx/ux set cache=on|off [quiet]  
This command allows you to turn on or off the write cache for a specified unit  
/cx/ux. This feature is supported on both 7000/8000 and 9000 models.  
By default, cache is on.  
Write cache includes the disk drive cache and controller cache. Note that for  
some configuration types, there is only disk drive cache and no controller  
cache (for example, JBOD).  
The following table shows the supported RAID types for caching as a  
function of controller model and logical unit type. N/A (Not Applicable)  
refers to cases where the given logical unit type is not supported on a  
particular controller model.

/cx/ux set identify=on|off  
This feature only applies to 9550SX, 9590SE, and 9650SE model controllers.  
This feature requires an enclosure that uses an integrated AMCC/3ware CCU  
(chassis control unit). (Check the 3ware web site for a list of chassis vendors  
that support enclosure services, as they become available.) For additional  
information about enclosure-related commands, see “Enclosure Object  
This command allows you to identify a unit within an enclosure by blinking  
the LEDs associated with the drive slots of the specified unit.  
Example:  
//localhost> /c0/u0 set identify=on  
Sending Identify request for unit /c0/u0 to [on] ... Done.  
/cx/ux set ignoreECC=on|off  
This feature only applies to 9000 series controllers.  
This command allows you to set the ignoreECC policy for a given unit.  
When ignoreECC policy is set to off, if a rebuild process encounters bad  
sectors on the source disk, the rebuild will fail. When ignoreECC is set to on,  
such errors are ignored, and the rebuild will continue. When you use  
ignoreECC, a file system check is recommended following the rebuild, to  
insure data integrity.  
By default, ignoreECC is off.

/cx/ux set name=string  
This command allows you to name the unit with an arbitrary name. You can  
use this name in conjunction with the unit serial number to cross-reference  
with the unit. The system does not check to ensure uniqueness of names, so be  
careful to assign different names to each unit.  
Note: The unit’s serial number is automatically assigned when the unit is created  
and is not changeable.  
/cx/ux set qpolicy=on|off  
This command applies only to 9550SX, 9590SE, and 9650SE controllers.  
This command sets the queue policy of the firmware. If the queue policy is  
on, the firmware utilizes the drive queueing policy. If some of the drives in  
the unit do not support any queueing policy, this policy will have no effect on  
those drives.  
By default, qpolicy is on.  
Example:  
//localhost> /c0/u5 set qpolicy = on  
Setting Command Queuing Policy for unit /c0/u5 to [on] ... Done.  
/cx/ux set storsave=protect|balance|perform [quiet]  
This command applies only to 9550SX, 9590SE, and 9650SE model  
controllers.  
This command sets the storsave policy to be either protect, balance, or  
perform when the unit write cache is enabled. The default setting is protect.  
The storsave policy adjusts several factors that control the balance between  
protection and performance on a unit. There is a trade-off among the available  
settings. The following description about the settings should help you to  
decide which one is suitable to you and your application. You will find further  
discussion of this setting in the 3ware Serial ATA RAID Controller User  
Guide, under “About StorSave Profile Levels” on page 117.

Unit Object Commands  
protect provides the maximum data protection among the controller settings.  
When storsave is set to protect mode, it means:  
When the unit becomes degraded, the write cache will be disabled.  
Write journaling is enabled. All data flushing from controller cache will  
be flushed to media.  
Incoming FUA (Force Unit Access) host requests will be honored unless  
a BBU is installed and enabled, in which case, they will be ignored.  
perform provides the maximum performance and least data protection of the  
three controller settings. When storsave is set to perform mode, it means:  
When the unit becomes degraded, the write cache will not be disabled.  
Write journaling is disabled. All data flushing from controller cache will  
be flushed to disk. If a BBU is present, this essentially disables the BBU  
for this unit.  
Incoming FUA (Force Unit Access) host requests will be honored.  
If you set the storsave policy to perform, a confirmation message will warn  
you that there could be data loss in the event of a power failure.  
balance provides more data protection than perform mode but less data  
protection than protect mode, and provides better performance than protect  
mode but less performance than perform mode. When storsave is set to the  
balance mode, it means:  
When the unit becomes degraded, the write cache will not be disabled.  
Write journaling is disabled, if no BBU is present, and is enabled, if a  
BBU is present. All data flushing from controller cache will be flushed to  
media if a BBU is installed and enabled. Otherwise, data will be flushed  
to disk only.  
Incoming FUA (Force Unit Access) host requests will be honored unless  
a BBU is installed and enabled, in which case, they will be ignored.  
quiet is used for non-interactive mode. No confirmation is given and the  
command is executed immediately. This is useful for scripting purposes.

/cx/ux migrate type=RaidType [disk=p:-p]  
[group=3|4|5|6|7|8] [stripe=Stripe] [noscan]  
[nocache] [autoverify]  
This feature only applies to 9000 series controllers.  
This command allows you to change the existing configuration of a unit with  
type=RaidType. You can make three types of changes:  
Increase the capacity  
Change the RAID level (with the same or increased capacity)  
Change the stripe size  
The unit that results from the migration is subject to the same rules and  
policies that apply when creating a new unit with the /cx add command. For  
example, a valid number of disks and parameters must be specified.  
The unit to be migrated must be in a normal state (not degraded, initializing,  
or rebuilding) before starting the migration.  
The destination unit must use all source disks and potentially augment the  
number of disks in the disk=p:-p disk list. Unspecified parameters are  
assigned the default values (stripe size of 64K, write cache enabled,  
autoverify disabled, and ignoreECC disabled). Both source name and serial  
number will be carried over to the destination unit.  
A special case of this command is when the source unit has a type of RAID1  
and destination unit has a type of single. In this case, the migrate command  
splits both drives into two identical single disks. The disk name will be  
duplicated on the destination units, but the source unit serial number will not  
be carried over to the new unit. The new destination unit will have its own  
serial number.  
type=RaidType specifies the RAID type of the destination unit. Possible unit  
types include raid0, raid1, raid5, raid6, raid10, raid50, or single.  
For example, type=raid5 indicates the destination unit is RAID-5. The  
type=single is a special case of the migrate command. It splits the source unit  
RAID-1 or TWINSTOR into multiple Single units.  
Note: You can only migrate a unit to a RAID level that has the same or more  
capacity as the existing one. A four-drive RAID 5 unit can migrate to a four-drive  
RAID 0, but a four-drive RAID 0 unit cannot migrate to a four-drive RAID 5, without  
adding another drive, due to the need for additional storage capacity for parity bits.  
The following table illustrates valid migration paths:

disk=p:-p.. consists of a list of ports (disks) to be used in addition to the  
source disks in the construction of the destination unit. One or more ports can  
be specified. Multiple ports can be specified using a colon (:) or a dash (-) as  
port index separators. A dash indicates a range and can be mixed with colons.  
For example disk=0:1:2-5:9:12 indicates port 0, 1, 2 through 5 (inclusive), 9  
and 12.  
group=3|4|5|6|7|8 indicates the number of disks per group for a RAID 50  
type. (This attribute can only be used when type=raid50.) Recall that a RAID  
50 is a multi-tier array. At the bottom-most layer, N number of disks per group  
are used to form the RAID 5 layer. These RAID 5 arrays are then integrated  
into a RAID 0. This attribute allows you to specify the number of disks in the  
RAID 5 level. Valid values are 3, 4, 5, 6, 7, and 8. For example group=3  
indicates 3 disks of RAID 5 at the bottom layer of RAID 50.  
Note that a sufficient number of disks are required for a given pattern or disk  
group. For example, given 6 disks, specifying 3 will create two RAID 5  
arrays. With 12 disks, specifying 3 will create four RAID 5 arrays under the  
RAID 0 level. With only 6 disks a grouping of 6 is not allowed, as you would  
basically be creating a RAID 5.  
The default RAID 50 grouping varies, based on number of disks. For 6 and 9  
disks, default grouping is 3. For 8 disks, the default grouping is 4. For 10  
disks, the default grouping is 5, and for 12 disks, the disks can be grouped into  
groups of 3, 4, or 6 drives (the group of 4 drives is set by default as it provides

the best of net capacity and performance). For 15 disks, the disks can be  
grouped into groups of 3 or 5 drives. For 16 disks, the disks can be grouped  
into groups of 4 or 8 drives.  
Note that RAID-10 always has group=2, so an attribute specifying it’s group  
is not necessary.  
stripe=Stripe consists of the stripe size to be used. The following table

noscan attribute instructs CLI not to notify the operating system of the  
creation of the new unit. By default CLI will inform the operating system.  
One application of this feature is to prevent the operating system from  
creating block special devices such as /dev/sdb and /dev/sdc as some  
implementations might create naming fragmentation and a moving target.  
nocache attribute instructs CLI to disable the write cache on the migrated  
unit. Enabling write cache increases write performance at the cost of potential  
data loss in case of sudden power loss (unless a BBU or UPS is installed). By  
default the cache is enabled. To avoid the possibility of data loss in the event  
of a sudden power loss, it is recommended not to set nocache unless there is a  
BBU (battery backup unit) or UPS (uninterruptibleuninterruptible power  
supply) installed..

Unit Object Commands  
autoverify attribute enables the autoverify attribute on the unit that is to be  
migrated. For more details on this feature, see “/cx/ux set autoverify=on|off”  
Migration Process  
In all cases of migration, the background migration process must be  
completed before the newly sized unit is available for use. You can continue  
using the original unit during this time. Once the migration is finished, a  
reboot will be required if you are booted from the unit. For secondary storage,  
depending on your operating system, you may need to first unmount the unit,  
then use CLI commands to ‘remove’ and ‘rescan’ the unit so that the  
operating system can see the new capacity, and then remount the unit. For  
You may also need to resize the file system or add a new partition. For  
instructions, consult the documentation for your operating system.  
Warning: It is important that you allow migration to complete before adding drives  
to the unit. Making physical changes to the unit during migration may cause the  
migration process to stop, and can jeopardize the safety of your data.  
Example of splitting a mirror  
//localhost> /c1/u3 migrate type=single  
Indicates that u3 should be split into Single units. In this case, u3 is a RAID-1  
and the Migrate command splits u3 into u3 and ux, each with a RAID type of  
Single.  
Warning: Make sure that no I/O is pending before splitting a mirror. If the Raid 1 is  
the boot device, you should boot from a different device before splitting the mirror.  
Example of capacity expansion  
//localhost> /c0/u3 migrate type=raid10 disk=10-11 stripe=16  
Indicates that the destination unit has a RAID type of raid10 and has added  
the disks 10 and 11 to the disks in the existing unit u3.

Port Object Commands  
Port Object Commands  
Port Object Messages are commands that provide information and perform  
actions related to a specific disk, attached to a port, such as /c0/p0. You use  
port object commands for such tasks as seeing the status, model, or serial  
number of the drive.  
Syntax  
/cx/px show  
/cx/px show attribute [attribute ...] where attributes are:  
capacity|firmware|identify (9550SX, 9590SE, 9650SE)|  
lspeed (9550SX, 9590SE, 9650SE)|model|  
ncq (9550SX, 9590SE, 9650SE)|serial|smart|status  
/cx/px show all  
/cx/px remove [noscan][quiet]  
/cx/px set identify=on|off (9550SX, 9590SE, 9650SE)  
/cx/px show  
This command shows summary information about the specified disk attached  
to port /cx/px. Typical information looks like:  
Example:

Port Object Commands  
/cx/px remove [noscan] [quiet]  
This command allows you to remove (or export) a port (or drive) /cx/px.  
Exporting a port instructs the firmware to remove the specified port from its  
pool of managed ports, but does not retain the DCB (Disk Configuration  
Block) metadata on the attached disk. You can import (or re-introduce) the  
port by rescanning the controller.  
noscan is used to not inform the operating system of this change. The default  
is to inform the operating system.  
quiet is for non-interactive mode.  
Warning: Use caution when using this command as this operation will degrade  
any redundant units. This command will fail if you attempt to remove a drive from a  
non-redundant unit. After the drive is removed in CLI it can be removed physically,  
without powering down the system if a hot swap carrier is available. System hangs  
and damage can occur if a hot swap carrier is not used.  
/cx/px set identify=on|off  
This command applies only to 9550SX, 9590SE, and 9650SE model  
controllers.  
This command sets the LED status of the port to on or off. If identify is set to  
on, the firmware activates the setting of the corresponding LED of the port on  
the controller and causes it to blink.  
Note: This command is equivalent to “/ex/slotx set identify=on|off” on  
Note: This feature requires an enclosure that uses an integrated AMCC/3ware  
CCU (chassis control unit). (Check the 3ware web site for a list of chassis vendors  
that support enclosure services, as they become available.) For additional  
information about enclosure-related commands, see “Enclosure Object

The command output indicates that the battery capacity was last measured on  
01-Jul-2004. The battery is estimated to last for 72 hours from the last tested  
date. In this example, the BBU unit is currently testing the battery. Both  
voltage and temperature are normal. The BBU is not ready to backup the write  
cache on the controller (due to the testing). (For complete information about  
the BBU, see the user guide that came with your 3ware RAID controller).  
Note: If the BBU is either not present or disabled, the following will be displayed  
after the command //localhost> /c0/bbu show.  
Error: (CLI:053) Battery Backup Unit is not present.

BBU Object Commands  
/cx/bbu show attribute [attribute ...]  
This command shows the current setting of the given attribute(s) on the BBU  
board. One or many attributes can be specified. Specifying an invalid attribute  
will terminate the loop. Possible attributes are: batinst, bootloader, cap, fw,  
lasttest, pcb, ready, status, serial, temp, volt.  
/cx/bbu show status  
This command shows the status of the BBU. Possible values are:  
Testing. A battery test is currently in progress. This test may take up to 24  
hours to complete. During the test, the BBU is not capable of backup  
operation and the write cache of the RAID controller is also disabled. If the  
test is completed with no error and the BBU status changes to WeakBat or  
OK, the write cache will be re-enabled. If a Fault, Failed or Error occurs  
during the test, the write cache remains in the disabled state until the problem  
is fixed.  
Charging. The BBU is currently charging the battery. Charging is started  
automatically by the BBU whenever necessary. During charging, the BBU is  
not capable of backup operation and the write cache is disabled. Once the test  
is completed with no error and the BBU status changes to OK, the write cache  
will be re-enabled. If a FAULT or ERROR occurs during the test, the write  
cache remains in the disabled state until the problem is fixed.  
Fault. A battery fault is detected. The BBU is not capable of backup operation  
and the write cache is disabled. Replace the battery and/or the BBU board as  
soon as possible so that the write cache will be enabled again.  
Error. A BBU error is detected. The BBU is not capable of backup operation  
and the write cache is disabled. Replace the battery and/or the Battery Backup  
Unit as soon as possible so that the write cache will be enabled again.  
Failed. The battery failed a test. In this state, the BBU is not capable of  
backup operation and the write cache is disabled. We recommend you replace  
the battery and/or the Battery Backup Unit as soon as possible so that the  
write cache will be enabled again.  
WeakBat. The BBU is functioning normally and is online and capable of  
backing up the write cache. However, the battery is weak and should be  
replaced.  
OK. The BBU is ready, online and capable of backing up the write cache.

taken during the last test. If you have not run the BBU test command for some time,  
this number can be misleading. For information about running a test, see “/cx/bbu  
/cx/bbu show volt  
This command shows the voltage status of the battery. The status can be OK,  
HIGH, LOW, TOO-HIGH, and TOO-LOW. The HIGH and LOW are in  
warning range. TOO-HIGH and TOO-LOW are out of the operating range  
and indicate that it is time to replace the battery. (Contact AMCC to obtain a  
replacement battery.)  
/cx/bbu show temp  
This command shows the temperature status of the battery. The status can be  
OK, HIGH, LOW, TOO-HIGH, and TOO-LOW. The HIGH and LOW are in

/cx/bbu test [quiet]  
This command starts the battery capacity test. The test may take up to 24  
hours to complete. During the test, the BBU is not capable of backup  
operation and the write cache of all units attached to that controller is  
disabled. Once the test is completed with no error and the BBU status returns  
to OK, the write cache will be re-enabled.  
Note: Once started, the test can not be terminated before it completes. Write  
cache cannot be enabled until the test completes.  
AEN (Asynchronous Event Notification) messages are also generated by  
controllers to notify the user of the command status.  
Check for AENs with the alarms command /cx show alarms [reverse]. Using  
the “reverse” attribute displays the most recent AEN message at the bottom of  
the list. (For a list of all AENs, see the user guide that came with your 3ware  
RAID controller.)  
/cx/bbu enable  
This command enables BBU detection on the controller. If the BBU is Ready,  
the controller will utilize BBU functionality in the event of a power failure.  
/cx/bbu disable [quiet]

Enclosure Object Commands  
Enclosure Object Commands  
Enclosure object commands provide information and perform actions related  
to a specific enclosure, such as /e0 and its elements, such as /e0/slot0.  
Enclosure object elements include slot, fan, and temperature sensor elements.  
These commands are supported on the 9550SX, 9590SE, and 9650SE  
controllers, when an appropriate enclosure is used. The enclosure must use an  
integrated AMCC/3ware CCU (chassis control unit). (Check the 3ware web  
site for a list of chassis vendors that support enclosure services, as they  
become available.) If you purchased an enclosure directly from a third-party  
vendor, the appropriate EPCT (Enclosure Port Configuration Table) must  
have been downloaded to the controller in order to take advantage of these  
commands.  
Note. Not all enclosure features may be available on enclosures that use an  
integrated AMCC/3ware CCU.

/ex/slotx set identify=on|off  
This command causes the slot to be identified by blinking the LED associated  
with it, or turns off identification of the LED for this slot.  
Setting identify to on will cause the LED associated with that slot to blink,  
provided that the EPCT has been set to associate “identify” with “blinking,”  
as is the case in the 3ware Sidecar.  
Note: This command is equivalent to “/cx/px set identify=on|off” on page 81.

object name, or by typing a question mark (?) at the point in a command  
where you are uncertain what the attributes are.  
Help with specific commands  
If you enter the help command at the top level, you are considered to be in the  
Shell Object, and the help command will provide help on the Shell commands  
focus, show, flush, rescan, and commit. Using the help command on objects  
(such as /cx, /cx/ux, /cx/px, /cx/bbu, /ex, /ex/slotx, /ex/fanx, and /ex/tempx),  
displays all possible sub-commands associated with the object.  
For example: help on the controller object /cx, will display all the sub-  
commands associated with the controller /cx, like this:

Command Logging  
This feature logs controller commands from both CLI and 3DM2 into a file.  
You may be asked to supply this logfile to tech support for troubleshooting.  
Set the environment variable TW_CLI_LOG to ON or OFF to enable or  
disable logging of controller commands into a log file called tw_mgmt.log.  
By default, TW_CLI_LOG is set to OFF. The command to start command  
logging varies by operating system.  
For FreeBSD, Redhat and SuSE, (bash, ksh, or sh), enter  
export TW_CLI_LOG=ON  
For Linux (chs C-shell), enter  
setenv TW_CLI_LOG ON  
For Windows, enter  
set TW_CLI_LOG=O  
In Linux, and FreeBSD, the log file is in /var/log directory.  
In Windows, the log file is in the 3DM2 installation directory if 3DM2 is  
installed in the system. Otherwise, it is in the current user home directory.  
Return Code  
While informative messages are written to standard output, error messages are  
written to standard error. On success, 0 is returned. On failure, 1 is returned.  
To view the return code for Linux:  
At the shell command prompt type:  
echo $?  
The screen prints either a 0 or a 1, depending on whether the command was  
successful or not.
