What You Need to Know Before You Begin
You should be familiar with computer hardware, data storage, RAID technology, and the
input/output (I/O) technology—Small Computer System Interface (SCSI), SAS, or Serial ATA
You should also be familiar with Direct-Attached Storage (DAS) or Network-Attached Storage
(NAS)—whichever is appropriate for your storage space—and Storage Area Network (SAN)
concepts and technology.
Note: Because this Guide covers multiple Adaptec RAID products, some of the features and
Terminology Used in this Guide
Because you can use your Adaptec RAID controller to manage data storage in a variety of
configurations from DAS to NAS to SAN, the generic term “storage space” is used to refer to
controller(s) and disk drives being managed with Adaptec Storage ManagerTM or the other
utilities described in this Guide.
Many of the terms and concepts referred to in this Guide are known to computer users by
multiple names. This Guide uses these terms:
●
●
●
●
Controller (also known as adapter, board, or card)
Disk drive (also known as hard disk, hard drive, or hard disk drive)
Enclosure (also known as a RAID enclosure, storage enclosure, or JBOD enclosure)
Array (also known as a container or logical drive)
Note: In DAS environments, Adaptec Storage Manager refers to arrays as logical drives.
Why? Your RAID controller creates arrays, which your operating system (and Adaptec
Storage Manager) recognizes as logical drives.
In NAS environments, Adaptec Storage Manager displays both arrays and logical drives. For
more information, refer to the Adaptec Storage Manager User’s Guide for Internal RAID
Storage on the Adaptec Storage Manager Installation CD.
How to Find More Information
You can find more information about your Adaptec RAID controller and the software and
utilities included with it by referring to these documents:
●
●
Readme.txt—Includes updated product information and known issues; located on the
RAID Installation CD.
Adaptec Storage Manager User’s Guide for Internal RAID Storage—Describes how to install
Storage Manager Installation CD.
●
●
Adaptec Storage Manager online Help—Describes how to use the Adaptec Storage Manager
software; accessible from the main window of Adaptec Storage Manager.

Adding Enhanced Features
As your storage needs change, you can enhance data protection and improve performance by
upgrading your Adaptec controller with extra features.
Currently, Adaptec offers the snapshot function as an upgrade feature which can be activated
with a feature key (sold separately). A snapshot is a frozen image of a logical drive at a particular
point in time. You can use this feature to back up your data to tape, clone a disk drive, or copy
the data to multiple servers.
Note: Snapshots are supported by Windows and Linux operating systems only.
To purchase a feature key, contact your Adaptec Reseller or refer to the Adaptec Web site at
section).
Using a Feature Key to Unlock Enhanced Features
When you receive a feature key, use Adaptec Storage Manager to unlock the new features. For
step-by-step instructions, follow the instructions in the online Help or the Adaptec Storage
Manager User’s Guide for Internal RAID Storage on the Adaptec Storage Manager Installation CD.

Storage or online Help.
for Internal RAID
Disk Drives for SAS Controllers
Disk Drives for SATA Controllers
Your SATA controller supports SATA disk drives only. You need one SATA port for each disk
drive you are connecting to your SATA controller.
Disk Drives for SCSI Controllers
Your SCSI controller supports Ultra320 SCSI disk drives. It also supports Ultra2 or higher
SCSI disk drives and peripherals, but at performance levels less than Ultra320. Adaptec does
not recommend using SCSI disk drives or peripherals older than Ultra2.
Note: High-voltage Differential (HVD) disk drives are not supported and will damage your
controller.
If you are mixing single-ended (SE) disk drives with Low-voltage Differential (LVD) disk
drives:
●
Ensure proper termination by using a cable (like the one included in the kit) with a built-
in multimode terminator and proper adapters.
●
●
Disable termination on all the SE disk drives.
Put LVD and SE disk drives on separate channels for the best performance.
Note: If you mix SE and Ultra320 disk drives on the same channel, the performance of the
Ultra320 disk drives is reduced to SE levels.

About Adaptec Storage Manager
Note: Currently, Adaptec Storage Manager is not supported on FreeBSD. To create and
Adaptec Storage Manager is a full-featured software application that helps you build a storage
space for your online data, using Adaptec RAID controllers and disk drives.
With Adaptec Storage Manager, you can group disk drives into logical drives and build in
redundancy to protect your data and improve system performance.
From a single workstation, you can use Adaptec Storage Manager to monitor and manage all
the controllers and disk drives in your storage space, including DAS and NAS.
When Adaptec Storage Manager is installed on a computer, the Adaptec Storage Manager agent
is also installed automatically. The agent is like a service that keeps your storage space running.
It’s designed to run in the background, without user intervention, and its job is to monitor and
manage system health, event notifications, task schedules, and other on-going processes on
that system. It sends notices when tasks are completed successfully, and sounds an alarm when
errors or failures occur on that system.
The agent uses less memory than the full application. If your storage space includes systems
that won’t be connected to monitors (and therefore won’t require the user interface), you can
choose to run the agent only on those systems instead of the full application. For more
information, refer to the Adaptec Storage Manager online Help, or to the Adaptec Storage
Manager User’s Guide for Internal RAID Storage on the Adaptec Storage Manager Installation
CD.

Failed Disk Drive Protected by a Hot Spare
When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is
automatically incorporated into the array and takes over for the failed drive.
To recover from the failure:
1
2
Remove and replace the failed disk drive (following manufacturer’s instructions).
If copyback is not enabled—In Adaptec Storage Manager, remove the ‘hot spare’
designation from the original hot spare (the disk drive that was built into the array). Then,
designate a new hot spare to protect the arrays on that controller.
If copyback is enabled—Data is automatically moved back to its original location once the
controller detects that the failed drive has been replaced. No action is required.
Failed Disk Drive Not Protected by a Hot Spare
When a array is not protected by a hot spare, if a disk drive in that array fails, remove and
replace the failed disk drive. The controller detects the new disk drive and begins to rebuild the
array.
If the controller fails to rebuild the array, check that the cables, disk drives, and controllers are
properly installed and connected. Then, if necessary, use Adaptec Storage Manager to rebuild
the array. For instructions, refer to the Adaptec Storage Manager User’s Guide
Storage or online Help.
for Internal RAID
Failure in Multiple Arrays Simultaneously
If there’s a disk drive failure in more than one array at the same time (one failure per array),
and the arrays have hot spares protecting them, the controller rebuilds the arrays with these
limitations:
●
●
A hot spare must be of equal or greater size than the failed disk drive it’s replacing.
Failed disk drives are replaced with hot spares in the order in which they failed. (The array
that includes the disk drive that failed first is rebuilt first, assuming an appropriate hot
spare is available—see bullet above.)
If there are more disk drive failures than hot spares, see Failed Disk Drive Not Protected by a Hot
If copyback is enabled, data is moved back to its original location once the controller detects
that the failed drive has been replaced.
Disk Drive Failure in a RAID 0 Array
Because RAID 0 volumes do not include redundancy, if a disk drive fails in a RAID 0 array, the
data can’t be recovered.
Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if
available).

Terminology Used in This Chapter
For convenience, SAS HBAs and SAS RAID controllers are referred to generically in this
chapter as SAS cards. HBAs, RAID controllers, disk drives, and external disk drive enclosures
are referred to as end devices and expanders are referred to as expander devices.
For convenience, this chapter refers to end devices and expander devices collectively as SAS
devices.
What is SAS?
Legacy parallel SCSI is an interface that lets devices such as computers and disk drives
communicate with each other. Parallel SCSI moves multiple bits of data in parallel (at the same
time), using the SCSI command set.
SAS is an evolution of parallel SCSI to a point-to-point serial interface. SAS also uses the SCSI
command set, but moves multiple bits of data one at a time. SAS links end devices through
direct-attach connections, or through expander devices.
SAS cards can typically support up to 128 end devices and can communicate with both SAS
and SATA devices. (You can add 128 end devices—or even more—with the use of SAS
67), Adaptec recommends that you not combine SAS and SATA disk drives within the same
array or logical drive. The difference in performance between the two types of disk drives may
adversely affect the performance of the array.
Data can move in both directions simultaneously across a SAS connection (called a link—see
page 64). Link speed is 600 MB/sec in full-duplex mode. A SAS card with eight links has a
maximum bandwidth of 4800 MB/sec in full-duplex mode.
Although they share the SCSI command set, SAS is conceptually different from parallel SCSI
physically, and has its own types of connectors, cables, connection options, and terminology,
as described in the rest of this chapter.

How Do SAS Devices Communicate?
SAS devices communicate with each other through links. A link is a physical connection
between two phys.
and each phy contains one transmitter and one receiver—one transceiver. A phy can belong to
one port only.

What’s a Phy?
Phys are part of the physical communication connection between SAS devices. Each phy
contains a transceiver that sends data back and forth between SAS devices.
When a connection is formed between two end devices, a link is established from a phy in one
port to a phy in the other port. As shown in the figure above, a wide port can support multiple
independent links simultaneously.
SAS cables physically connect one or more phys on one SAS device to one or more phys on
another SAS device.

What’s a SAS Port?
Note: Because the physical link between SAS devices is from phy to phy, rather than port to
port, a “port” is more of a virtual concept, different from what is normally considered a port on
other types of RAID controllers and storage devices.
A port is one or more phys. A narrow port contains one phy. A wide port typically contains four
phys.
same SAS address.
SAS card port options vary. A SAS card with four phys could be configured with one wide port,
with two wide ports that comprise two phys, or with four narrow ports each containing one
phy. (A wide port with four phys is referred to as a 4-wide or 4x port.)
What’s a SAS Address?
Each SAS port is identified with a unique SAS address, which is shared by all phys on that port.
For example, a SAS disk drive might have two narrow ports. Each port has one unique SAS
address. The single phy in each port uses its port’s SAS address.
In another example, a SAS device might have one 4-wide port. That port has one SAS address,
which is shared by all four phys in the port.
Unlike SCSI devices and SCSI IDs, SAS devices self-configure their SAS addresses. User
intervention is not required to set SAS addresses, and SAS addresses cannot be modified.
What’s a SAS Connector?
A SAS or mini-SAS connector is the physical plug or receptacle that you see on a SAS device.
It’s what you plug a SAS cable into, or the end of the SAS cable that’s being plugged in. (See SAS
A connector is what forms physical links between phys. Some SAS connectors can support
multiple links. The number of links a SAS connector can support is referred to as its width.
Narrow connectors support a single link; wide connectors support up to four links.
A single SAS device may have one or more connectors. A single SAS connector may help form
4-wide internal SAS connector forms links with four independent disk drives.)
What do SAS Cables Look Like?
Internal standard SAS cables are narrower than internal parallel SCSI cables. The connectors
vary in size depending on the number of links they support, from single link connectors to
4-wide (or larger) connectors. Internal fan-out cables let you attach four disk drives to a single
4-wide connector.
Mini-SAS connectors support both internal and external SAS connections. The mini-SAS
connectors are smaller than the standard SAS internal and external connectors. Mini-SAS
connectors support single and multilinks with the ability to scale to future speed needs.
For examples of some internal SAS/mini-SAS cables and an external SAS/mini-SAS cables, see

How are Disk Drives Identified in SAS?
numbers in this format:
XX:YY:ZZ
where XX is the disk drive count number, YY is the enclosure number, and ZZ is the slot
number (within the enclosure). If the disk drive is not installed in an enclosure, a double
dashes (--) appear instead of YY and ZZ (for instance, 01:--:--).
In parallel SCSI, XX is the disk drive’s channel number, YY is the target number, and ZZ is the
logical unit number (LUN).
What are the SAS Connection Options?
You can connect end devices to each other through direct cable connections and through
create large configurations.
Direct-attach Connections
In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card
with SAS or mini-SAS cables. One disk drive is attached to one SAS/mini-SAS connector with
one SAS/mini-SAS cable (or multiple disk drives are attached to one SAS/mini-SAS connector
The number of direct-attached disk drives is limited to the number of phys supported by the
Backplane Connections
In a backplane connection, disk drives and SAS cards are attached to and communicate with
each other through a system backplane.
The number of end devices is limited to the number of slots available on the backplane. For
example, the Adaptec S50 enclosure, which contains an expander, is a backplane connection
that supports up to 12 SAS or SATA disk drives.
Some backplanes support daisy-chain expansion to other backplanes. For example, you can
daisy-chain (connect one to the next) up to nine Adaptec S50 enclosures to a single SAS card in
a host system.

67
SAS Expander Connections
A SAS expander device literally expands the number of end devices that you can connect
large configurations of SAS end devices, including SAS cards and SAS and SATA disk drives.
With expander devices, you can build large and complex storage topologies.
There are two types of SAS expanders: fanout expanders and edge expanders. Each performs a
different role in a storage system. (For more information about how SAS expanders work, refer
to the STA Web site at www.scsita.org.)
You can connect up to 128 SAS ports to an edge expander. (A single edge expander can
therefore support up to 128 SAS addresses.)
You can connect up to 128 edge expanders to a fanout expander.
You can use only one fanout expander in any single SAS domain (a topology of SAS—and
possibly SATA—end devices and expander devices). A single SAS domain can therefore
comprise up to 16,384 SAS ports (and therefore up to 16,384 SAS addresses).
The next figure illustrates (in very basic terms) a SAS domain and shows how SAS cards, SAS
and SATA disk drives, and expander devices can fit together in a large data storage topology.

How is SAS Different from Parallel SCSI?
In summary, although SAS and parallel SCSI both use the SCSI command set, how they move
data from one place to another is very different. To support point-to-point serial data
transport, SAS introduces new types of connectors, cables, connection options, and
terminology.
Generally speaking, SAS is faster and more flexible than parallel SCSI, and provides more
options for building your storage space. SAS lets you mix SAS and SATA disk drives together,
and lets you connect many, many more devices.
This table describes many of the main differences between the two interfaces.

RAID 1 Enhanced Arrays....................................................................................................... 71
When you create arrays (or logical drives), you can assign a RAID level to protect your data.
Each RAID level offers a unique combination of performance and redundancy. RAID levels
also vary by the number of disk drives they support.
This appendix describes the RAID levels supported by your Adaptec RAID controller, and
provides a basic overview of each to help you select the best level of protection for your data
storage.

Understanding Drive Segments
A drive segment is a disk drive or portion of a disk drive that is used to create an array. A disk
drive can include both RAID segments (segments that are part of an array) and available
segments. Each segment can be part of only one logical device at a time. If a disk drive is not
part of any logical device, the entire disk is an available segment.
Nonredundant Arrays (RAID 0)
An array with RAID 0 includes two or more disk drives and provides data striping, where data
is distributed evenly across the disk drives in equal-sized sections. However, RAID 0 arrays do
not maintain redundant data, so they offer no data protection.
Compared to an equal-sized group of independent disks, a RAID 0 array provides improved I/O
performance.
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an
array with two 250 GB disk drives and two 400 GB disk drives can create a RAID 0 drive
segment of 250 GB, for a total of 1000 GB for the volume, as shown in this figure.

RAID 1 Arrays
A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the other (the
same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays
provide improved performance, with twice the read rate and an equal write rate of single disks.
However, capacity is only 50 percent of independent disk drives.
If the RAID 1 array is built from different- sized disk drives, the free space, drive segment size is
the size of the smaller disk drive, as shown in this figure.

RAID 1 Enhanced Arrays
A RAID 1 Enhanced (RAID 1E) array—also known as a striped mirror—is similar to a RAID 1
array except that data is both mirrored and striped, and more disk drives can be included. A
RAID 1E array can be built from three or more disk drives.
In this example, the large bold numbers represent the striped data, and the smaller, non-bold

RAID 10 Arrays
A RAID 10 array is built from two or more equal-sized RAID 1 arrays. Data in a RAID 10 array
is both striped and mirrored. Mirroring provides data protection, and striping improves
performance.
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an
array with two 250 GB disk drives and two 400 GB disk drives can create two mirrored drive
segments of 250 GB, for a total of 500 GB for the array, as shown in this figure.

RAID 5 Arrays
A RAID 5 array is built from a minimum of three disk drives, and uses data striping and parity
data to provide redundancy. Parity data provides data protection, and striping improves
performance.
Parity data is an error-correcting redundancy that’s used to re-create data if a disk drive fails.
In RAID 5 arrays, parity data (represented by Ps in the next figure) is striped evenly across the
disk drives with the stored data.
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an
array with two 250 GB disk drives and two 400 GB disk drives can contain 750 GB of stored
data and 250 GB of parity data, as shown in this figure.

RAID 5EE Arrays
A RAID 5EE array—also known as a hot space—is similar to a RAID 5 array except that it
includes a distributed spare drive and must be built from a minimum of four disk drives.
Unlike a hot spare, a distributed spare is striped evenly across the disk drives with the stored
data and parity data, and can’t be shared with other logical disk drives. A distributed spare
improves the speed at which the array is rebuilt following a disk drive failure.
A RAID 5EE array protects your data and increases read and write speeds. However, capacity is
reduced by two disk drives’ worth of space, which is for parity data and spare data.
In this figure, S represents the distributed spare, P represents the distributed parity data.

RAID 50 Arrays
A RAID 50 array is built from six to forty-eight disk drives configured as two or more RAID 5
arrays, and stripes stored data and parity data across all disk drives in both RAID 5 arrays. (For
Note: Because they support four disk drives only, the Adaptec 2420SA RAID controller can’t
support RAID 50 arrays.
The parity data provides data protection, and striping improves performance. RAID 50 arrays
also provide high data transfer speeds.
Drive segment size is limited to the size of the smallest disk drive in the array. For example,
three 250 GB disk drives and three 400 GB disk drives comprise two equal-sized RAID 5 arrays
with 500 GB of stored data and 250 GB of parity data. The RAID 50 array can therefore contain
1000 GB (2 x 500 GB) of stored data and 500 GB of parity data.

RAID 6 Arrays
A RAID 6 array—also known as dual drive failure protection—is similar to a RAID 5 array
because it uses data striping and parity data to provide redundancy. However, RAID 6 arrays
include two independent sets of parity data instead of one. Both sets of parity data are striped
separately across all disk drives in the array.
RAID 6 arrays provide extra protection for your data because they can recover from two
simultaneous disk drive failures. However, the extra parity calculation slows performance
(compared to RAID 5 arrays).
RAID 6 arrays must be built from at least four disk drives. Maximum stripe size depends on
the number of disk drives in the array.

Introduction to the ARC Utility
The ARC utility comprises these tools:
●
The Array Configuration Utility (ACU)—For creating and managing arrays, and
●
●
A -Select Utility—SerialSelect, SATASelect, or SCSISelect, for modifying your controller
Running the ARC Utility
If your Adaptec controller is connected to a RAID enclosure, power on your enclosure (or
enclosures) before you power on your computer.
Start or restart your computer. When prompted, press Ctrl+A.
During boot up, if your system has insufficient memory the following message will display.
“Adaptec RAID Configuration Utility will load after, system initialization. Please wait... Or press
<Enter> Key to attempt loading the utility forcibly [Generally, not recommended]”
Note: The first time you power on your computer after you install a new controller, the BIOS
may display a configuration that doesn’t match your system’s configuration. This is normal.
Navigating the ARC Utility
All the tools within the ARC utility are menu-based and instructions for completing tasks
appear on-screen. Menus can be navigated using the arrows, Enter, Esc, and other keys on your
keyboard.
Using the ACU to Create and Manage Arrays

Managing Existing Arrays
To view or modify existing arrays, select Manage Arrays from the main ACU menu.
From the Manage Arrays menu, you can:
●
View the properties of an array.
Note: Failed drives are displayed in a different text color.
●
●
●
Assign or remove hot spares.
Delete an array.
Caution: Before deleting an array, back up the data to avoid permanently losing it.
!
Creating Bootable Arrays
Note: You may need to change the system BIOS to modify the boot order. For more
information, refer to your computer’s documentation.
The controller always uses the lowest numbered array as its bootable array.
To make an array bootable:
1
2
Select Manage Arrays from the main ACU menu.
Select the array that you want to make bootable, then press Ctrl+B.
Note: You cannot make an array bootable while it’s building, verifying, or rebuilding.
The array’s number changes to Array 00, which makes this array the controller’s boot
array.

Restart your computer.
Initializing Disk Drives
If a disk drive appears grayed-out (unavailable for use in a new array), it may need to be
initialized.
To begin initializing a disk drive, select Initialize Drives from the main ACU menu.
Caution: Do not initialize a disk drive that is part of an array. Initializing a disk drive that’s
part of an array may make the array unusable.

81
Secure Erasing Disk Drives
When you perform a secure erase on a disk drive, all data on that disk drive is completely and
irretrievably eradicated. Secure erase performs three distinct writing passes to the disk drive
being erased—it does not just write zeros.
Performing a secure erase takes up to six times longer than clearing (or zeroing) a disk drive.
You may want to perform a secure erase only on disk drives that contain confidential or
classified information.
Note: To erase (or zero) a disk drive with non-classified information, you may choose to format
less time than the secure erase option.
To begin a secure erase, select Secure Erase from the main ACU menu, then select Y (yes). To
return to the main ACU menu once the secure erase has begun, press Esc.
The selected disk drive(s) cannot be used until the erase is complete.
Stopping a Secure Erase
To stop a secure erase in progress:
1
2
In the main ACU window, select Secure Erase.
Select the disk drive being secure erased, then press Ctrl+Q.
The secure erase stops and the ACU returns to its main window.
Using the -Select Utility to Modify Controller Settings
Included in the ARC utility is a tool for modifying the settings of your controller and the disk
drives connected to it. This utility is called SerialSelect, SATASelect, or SCSISelect, depending on
what type of controller you have.
Opening a -Select Utility
To open a -Select utility, start the ARC utility (see page 79), select the -Select utility, then press
Enter.
Follow the on-screen instructions to modify the settings of your controller and connected disk
drives as required.
Applying Changes and Exiting
1
To exit a -Select utility, press Esc until you are prompted to exit.
If you modified any settings, you are prompted to save the changes before you exit.
Select Yes to exit, then press any key to restart your computer.
Any changes you made take effect after the computer restarts.

The ACU for DOS runs from a floppy disk which you can create using the RAID Installation
CD that came in your Adaptec RAID controller kit.
To create the ACU floppy disk:
1
Insert your RAID Installation CD into the CD drive, then browse to this file:
packages/firmware/controllermodel/acu.exe
Where controllermodel is the model number of your Adaptec RAID controller.
Insert a bootable floppy disk and copy the acu.exe file to it.

Running the ACU Using Scripts
To work in the ACU using scripts:
1
The computer boots to the DOS command line.
2
Type ACUon the command line, specify a script file, and specify either the /P or /R switches
listed in the following table. (Don’t specify both.)
You may also add one or both of the optional switches.
Note: Command line syntax is not case sensitive.
Switch
Description
/P <file>
Playback Mode—The ACU reads the contents of the specified script file and
creates arrays and configures channel settings based on the keywords
/R <file>
/L <file>
Record Mode—The ACU writes a RAID controller’s existing array configuration
to a specified script file, which lets you create the same configuration by
running the ACU in playback mode (/P switch) with the resulting script. See
(Optional) Log Filename Switch—If you include this switch, the ACU records
its activity and any errors it encounters in the log file. If you do not include this
switch, the ACU displays activity and errors on the screen.
The file is a standard MS-DOS file, which can include a drive, directory,
filename, and extension. Only the filename and extension (.log) are required. If
no drive or directory is specified, the file is placed in the same location as the
ACU executable.
/C <number> (Optional) Controller Number Switch—In systems with more than one
controller, this switch specifies which controller to change, where number is
the controller number. The default controller number is 0.
Note—The number assigned to a particular controller depends on the
controller’s physical PCI slot and the order in which your system scans its PCI
slots.
About Playback Mode
In this mode, the ACU reads the contents of the specified script file and creates arrays based on
the keywords specified in the script.
The syntax is ACU /P <file> where file is the name of the script file. The file parameter can
include a drive, directory, filename, and extension. If no drive or directory is specified, the file
is placed in the same location as the ACU executable.
Note: The script file syntax allows only one hot spare to be assigned to an array. Therefore,
when recording a RAID 10, the ACU can’t map hot spares assigned to the individual mirror sets
in the resulting script file. Instead, the ACU creates a single list for all hot spares assigned to
.

89
About Record Mode
Note: You can also create a script file manually (see the following section).
In Record Mode, the ACU writes a RAID controller’s existing array configuration to a specified
script file, which lets you create the same configuration by running the ACU in Playback Mode
(/P switch) with the resulting script.
You can only record one RAID controller at a time with Record Mode. Record multiple RAID
controllers separately using separate script files.
The syntax is ACU /R <file>where file is the name of the script file. The file parameter can
include a drive, directory, filename, and extension, but only the filename and extension are
required. If no drive or directory is specified, the file is placed in the same location as the ACU
executable.
The ACU supports only a subset of available array types. If it encounters an array it can’t
create, a warning displays (or is recorded in the log file, if the /L switch is used); no keywords
for that array are recorded in its script file.
When recording an array, the ACU always uses the default Wait setting (equivalent to
Wait=Yes) unless you edit the script file and include Wait=No in the array’s definition block.
Creating the Script File Manually
Script files contain blocks:
●
●
The syntax rules are:

Each keyword must start its own line.
Syntax is not case sensitive.

Array Keyword
Array is a required keyword, indicating the start of an array definition block. The syntax is
Array=<label>, where label is an optional alphanumeric string.
For example:
Array=MyData
Drives Keyword
Drives is a required keyword, specifying the devices to use in creating the array. There is no
default value.
A disk drive is identified by its channel number, ID (target), and LUN, separated by colons; for
example, 0:0:0or 0:1:0. Separate multiple disk drive identifiers with commas.
Prior to creating any new arrays, the ACU initializes any drives specified by the Drives
keyword. If a disk drive is specified in more than one array definition block in a script, it is
initialized only once.
Caution: Any disk drive specified within the script file is initialized, which destroys any
data on that disk drive.

For example:
Drives=0:0:0
Drives=0:0:0,0:1:0,0:2:0

91
End Keyword
End is a required keyword, indicating the end of the block.
HotspareDrives Keyword
Hotspare Drives is an optional keyword, specifying the hot spares to assign to the array. The
not specified, no hot spares are assigned to the array.
For example:
HotspareDrives=0:0:0,0:1:0
The same disk drive can be assigned to protect multiple arrays (as a pool spare). Once a pool
spare is used by a failed disk drive, however, it is no longer available to protect the other arrays
its assigned to.
This keyword does not verify that the available space on the specified hot spares is sufficient to
serve as failover for the array.
When assigning hot spares to a multilevel array, Hotspare Drives assigns all the hot spares in
the list to all arrays within the multilevel array.
InitializeAll Keyword
If you want the ACU to initialize all drives connected to the controller and delete any existing
arrays before any new arrays are created, even those that are not specified in any Drives
keyword definition, specify InitializeAll=Yes. Otherwise, the ACU initializes only those drives
specified by the Drives keyword.
Caution: Initializing a disk drive automatically deletes any existing arrays with that disk
drive as their member.
!
Possible values:
●
●
Yes—Initialize all drives.
No (default)—Do not initialize all drives; only those drives specified with the Drives
keyword are initialized.
For example:
Type=Volume
Type=RAID1
InitializeAll is a global keyword that you need to specify only once.
InitializeAll is always performed prior to array creation regardless of its position in the script.
If both InitializeAll=Yes and InitializeAll=No are specified in the same script file,
InitializeAll=Yes is always the overriding value.
If an array is deleted during a Build/Verify process, the process is automatically terminated.

Method Keyword
Method is an optional keyword, indicating which method to use when creating a redundant
(RAID 1, 5, and 10) array. Possible values:
●
●
●
Build (the default)—Perform a Build/Verify process on the array. Takes longer than Clear,
but allows you to begin using the array immediately.
Clear—Clear the array. Faster than a Build/Verify process, but you have to wait for the
operation to be completed before you can begin using the array.
Quick Init—Makes the array available immediately, but does not accomplish a Build/
Verify. Parity and mirror information is created as data is written to the disk drive (called
full-stripe write mode), which reduces overall array performance. Maximum performance
is achieved by starting and completing a Build/Verify.
For example:
Method=Build
ReadCache Keyword
ReadCache indicates whether the array uses read caching.
Possible values:
●
●
Yes (default)—Enable read caching.
No—Disable read caching.
For example:
ReadCache=Yes
Size Keyword
The Size keyword specifies the size of the array. Specify Maximum (the default) to create an
array using the maximum available space, based on the array type and drives selected.
Otherwise, specify the size as an integer or a decimal number, followed by the unit
keyword MB (megabytes), GB (gigabytes), or TB (terabytes).
Note: A unit keyword is required with a numeric size value. If no unit keyword is specified, the
ACU exits with an error.
For example:
Size=2.5GB
Size=300MB
Size=Maximum
StripeSize Keyword
The StripeSize keyword specifies the stripe size (in MB) written to each member of a striped
array (RAID 0, 5, or 10).
The possible values for StripeSize are 16, 32, 64, 128, 256, 512 and 1024 KB. Default is 256.
For example:
StripeSize=256

Appendix D: Using the Array Configuration Utility for DOS
●
93
Type Keyword
Type is a required keyword, indicating the array type. There is no default value. The possible
values: Volume, RAID0, RAID1, RAID5, RAID10, or RAID50.
Depending on the RAID levels supported by your RAID controller, additional possible values
are: RAID1E, RAID5EE, RAID6, RAID60.
Wait Keyword
Wait is an optional keyword that you can use to tell the ACU to allow the ACU to continue
while the Build/Verify or Clear completes in the background; specify Wait=No. Otherwise, the
ACU waits by default.
If the host is powered off before the Build/Verify or Clear process completes and is then
restarted, the process resumes without any user intervention.
For example:
Wait=Yes
Wait=No
WriteCache Keyword
The WriteCache keyword indicates whether write caching is used for this array if write caching
is supported for the system. Possible values are as follows:
●
●
Yes (default)—Enable the write cache.
No—Disable the write cache.
Setting an array’s WriteCache keyword to Yes might result in data loss or corruption during a
power failure.
For example:
WriteCache=Yes
Channel Definition Block Keywords—SCSI only
The channel definition block is optional. If used, it always begins with the keyword Channel and
ends with the keyword End. The channel definition block keywords are listed in this table.
Keyword
Channel
ControllerID
End
Description
Used to identify the channel.
Changes the SCSI ID of the controller.
Indicates the end of a channel definition block.
Channel Keyword
Channel is an optional keyword that begins a channel definition block and specifies the
channel number to which the channel keywords apply. Channels are numbered from zero to
the maximum number of channels on the controller minus one.
You can include multiple channel definition blocks within a script file, each beginning with a
channel keyword and value.
For example:
Channel=0

Appendix D: Using the Array Configuration Utility for DOS
●
94
ControllerID Keyword
ControllerID is an optional keyword to change the SCSI ID of the controller. Normally, the
SCSI controller is assigned SCSI ID 7 on each of its channels. You can specify any ID value
between 0 and 7.
Caution: Do not change the SCSI ID of the controller unless directed to do so by Adaptec
Technical Support.
!
For example:
ControllerID=7
End Keyword
End is a required keyword, indicating the end of the block.
ACU Error Codes
When the ACU detects an error, it reports the error and exits immediately. If a log file is
specified, the ACU writes the error code to the log file. Otherwise, it displays the error code on
the screen.
The possible error messages returned by the ACU are listed in this table.
Code Description

Sample Scripts
This MS-DOS command invokes the ACU and creates arrays on controller 1 based on the
array keywords defined in the script file A:\RAID.ACU. It also configures Channel 0 and saves
a log of the operation in the log file C:\RAID.LOG:
A:\> ACU /P A:\RAID.ACU /L C:\RAID.LOG /C1
Sample Scripts for SCSI and SAS Controllers
This sample script file is a sample RAID.ACU script as referred to in the ACU command above.
This script creates these arrays—a 500 MB single-disk volume, and a 2-GB two-disk drive
RAID 1 with a hot spare:
# Script to create volume, mirror, and RAID 5 arrays
# Create a 500MB volume labeled ‘MySystem’
Array=MySystem
Type=Volume
Size=500MB
Drives=0:0:0
End
# Create a 2GB mirror labeled ‘MyMirror’
Array=MyMirror
Type=RAID1
Size=2GB
# Use drives 1 and 2
Drives=0:1:0,0:2:0
# Disable write cache
WriteCache=No
# Assign 1 spare drive
HotspareDrives=0:3:0
End
This sample script file creates a maximum-size three-disk-drive RAID 5:
# Create a maximum size RAID 5 labeled ‘MyData’
Array=MyData
Type=RAID5
Size=Maximum
# Use the maximum stripe size
StripeSize=256
# Clear the array (don’t build/verify it)
Method=Clear
# Don’t wait for clear to complete
Wait=No
# Use drives 0, 1, 2
Drives=0:0:0, 0:1:0, 0:2:0

Using the Adaptec Flash Utility
E
In this appendix...
Before You Begin .................................................................................................................... 98
This chapter describes how to use the Adaptec Flash Utility (AFU), a text-based DOS utility
that you can use to update, save, or verify the RAID controller’s firmware BIOS and NVRAM.
Caution: Although the AFU contains safeguards to prevent you from accidentally damaging
your RAID controller’s flash contents, it is still important to use the AFU carefully and
!
correctly to avoid rendering your RAID controller inoperable.
Adaptec recommends that only advanced users familiar with working in DOS use the AFU.

System Requirements
●
MS–DOS version 5.0 or later.
Note: You can’t run the AFU from a DOS command prompt window under any version of
Windows.
●
At least 8 MB of extended memory.
Compatibility Notes
●
Supports HIMEM.SYS; compatible with other DOS drivers running under HIMEM.SYS
(for example, SMARTDRV.SYS and SETVER.SYS).
●
Does not support DOS extenders installed in memory, such as EMM386.SYS and
DOS4GW.
Before You Begin
1
Obtain the firmware (see the following section).
2
There are two ways to run the AFU:
1
2
Obtaining the Firmware
To obtain RAID controller firmware, go to:
●
The RAID Installation CD—Includes the AFU executable (AFU.exe) and a separate flash
image. The flash image may comprise multiple User Flash Image (UFI) files.
●
The Adaptec Web site—Download a new firmware file to get the most recent version of
AFU.

Appendix E: Using the Adaptec Flash Utility
●
99
Creating the Firmware Floppy Disks
Note: You will need at least two bootable MS-DOS floppy disks to complete this task.
You can’t create a bootable floppy disk using Windows 2000.
To create the firmware floppy disks:
1
Create a bootable MS–DOS floppy disk and copy these files to it:
●
AFU.exe
●
Axxxx01.ufi
where xxx is the model number of your controller.
Note: Most controller model numbers have a suffix (for example Adaptec 4800SAS). Check
that the .ufi file is the correct file for your controller before copying.
2
Create additional bootable MS–DOS floppy disks and copy each additional Axxxx0x.ufi
file to a separate floppy disk. (Some RAID controllers have two UFI files; some have four.
Each goes onto its own floppy disk.)
3
To use a menu-based AFU, see the following section.
Running the Menu-based AFU
To run the menu-based AFU:
1
Shut down your operating system and reboot to DOS from a bootable MS-DOS floppy
disk or from a DOS partition on a bootable drive. (You can use a disk drive connected to
the controller you are updating.)
2
3
At the DOS command prompt, type AFUwith no arguments.
The AFU’s main menu is displayed.
Select Select Controllers, then select the Adaptec RAID controller(s) to be flashed.
To update multiple RAID controllers in the same system, update the boot controller’s flash
first, restart the computer, then update the flash for the remaining controllers.
4
5
Select Select an Operation.
Choose the operation you want, then follow the on-screen instructions to complete the
task:
●
●
●
Update—Updates all the flash components on a RAID controller with the flash image
data from the UFI file.
Save—Reads the contents of a RAID controller’s flash components and saves the data
to a UFI file, which you can use to restore a RAID controller’s flash if required.
Verify—Reads the contents of a RAID controller’s flash components and compares it
to the contents of the specified UFI file.
●
●
Version—Displays version information about a RAID controller’s flash components.
List—Lists all supported RAID controllers detected on your system.

6
Complete the flash operation and restart your computer before trying to use the RAID
controller again. (You can not use your RAID controller while you are updating its flash.)
Running the AFU from the Command Line
To run the AFU from the command line:
1
Power off your computer, insert the first AFU floppy disk, then power on your computer.
If your computer isn’t set up to boot from the bootable floppy disk, enter the system setup
utility to change the setting.
2
you want.
Note: To find a controller number, type AFU LIST, then press Enter.
The AFU processes the command, prompts you to insert additional floppy disks as needed,
exits, and reports either success or an error message code.
AFU Commands
This section lists the available AFU commands.
List
Displays the AFU-supported RAID controllers installed on your computer. Also displays the ID
numbers assigned to each controller.
You don’t have to restart the computer after completing this command.
This example shows a typical system response to a LIST command:
A:\> AFU LIST
Adaptec Flash Utility V4.0-0 B5749
(c)Adaptec Inc. 1999–2005. All Rights Reserved.
Controllers Detected and Recognized:
Controller #0 (03:05:00) Adaptec Adaptec 2230SLP
Save
Saves the contents of a RAID controller’s flash in a UFI file. The name of the UFI file is based
on the controller type and can’t be changed.
You must restart the computer following a SAVE command.
The command syntax for the SAVE command is
AFU SAVE [/C<Controller ID>] [/D <UFI File Path>]
Download from Www.Somanuals.com. All Manuals Search And Download.
Appendix E: Using the Adaptec Flash Utility
●
101
These switches are available:
●
/C <Controller ID>—One or more RAID controller IDs representing the set of RAID
controllers on which to perform the specified command. The default is 0; if the computer
has multiple RAID controllers, the AFU defaults to controller 0 unless you specify
otherwise.
For example:
To specify a single RAID controller ID: /C 0
To specify multiple IDs separated by commas: /C 0,2
To indicate all RAID controllers: ALL
If you are using multiple RAID controllers, you must specify the controller you want by
using the /C switch; otherwise, the AFU displays an error message and exits.
●
/D <UFI File Path>—Specifies the path where the UFI files are located. If you do not
specify the /D switch, the AFU looks for (or creates) its UFI files in the default location.
You cannot specify the name of a UFI file, only its path. UFI filenames are predefined,
based on the RAID controller type.
In this example, the AFU saves flash contents from RAID controller 0 to a UFI file in the
current default drive and directory:
A:\> AFU SAVE /C 0
In this example, the AFU saves flash contents from Controller 1 to a UFI file in
C:\UFI_FILES:
A:\> AFU SAVE /C 1 /D C:\UFI_FILES
Update
Updates the flash components of one or more RAID controllers on your computer from the
flash image data in a UFI file. You must restart the computer following an UPDATE command.
The command syntax for the UPDATE command is:
AFU UPDATE [/C<Controller ID>] [/D <UFI File Path>]
This example shows a typical system response after an update.
A:\> AFU UPDATE /C 0
