Supported RAID Types  
RAID is an acronym for either Redundant Array of Independent  
Disks or Redundant Array of Inexpensive Disks. The goal of RAID  
is to provide higher capacity, performance and/ or reliability from  
combinations of disk drives than it is practical to achieve with a  
single drive.

Introduction  
Adaptec RAID controllers support the following types of array:  
RAID-0  
A RAID-0 is created by striping data across two or more disk  
drives. Simple striping like this creates no redundancy to protect  
the data, but by sharing the load equally across multiple drives, it  
does provide the best read and write performance of any RAID  
type.

RAID-1  
A RAID-1 must contain only two disk drives. All data stored on the  
array is written to both drives. This duplication, or mirroring, of  
the data provides redundancy, ensuring that if one drive fails no  
data loss will occur.

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
The cost of this redundancy is inefficient use of capacity, because  
all data is written to both drives, only half of the total capacity is  
available.  
RAID-1 offers no write performance advantage over a single drive,  
but read performance benefits from being able to share the load  
between two drives.  
RAID-5  
A minimum of three drives is required to create a RAID-5. Like a  
RAID-0, data is striped across the drives, however in the case of a  
RAID-5, the capacity of one drive is used to store parity  
information. The controller generates this parity data every time  
data is written to the array, and it is distributed in stripes across all  
the drives.  
In the event of a drive failure, the contents of the failed drive can be  
rebuilt from the data and parity on the remaining drives.

Using parity minimizes the capacity cost of redundancy. Since only  
one drive is used to store parity, the worst case of a three-drive  
RAID-5 only loses one third of the total capacity, for arrays with  
more drives the lost capacity is smaller.  
RAID-5 write performance is limited by the need to generate parity  
data for every write. Read performance is good because the load is  
spread equally across all the drives.

Introduction  
RAID-10  
A RAID-10 is an example of a dual-level array and is created by  
using two or more equal-sized RAID-1s to create a RAID-0.

Second-Level Arrays  
The top level RAID-0 shares the load among the second level  
RAID-1s, improving both read and write performance. Since  
second level arrays are RAID-1, only half the total capacity of the  
drives in the array is available.

Second-Level Arrays  
The top level RAID-0 shares the load among the second-level  
RAID-5s, improving both read and write performance. The second  
level RAID-5s use of parity provides efficient redundancy.  
Simple Volume  
A simple volume consists of a single disk drive.  
Spanned Volume  
A spanned volume is created by joining two or more disk drives.  
The drives do not have to be of equal capacity and are connected  
end-to-end. A spanned volume offers no redundancy and no  
performance advantage over a single drive.

Introduction  
RAID Volume  
A RAID volume is created by joining two or more single-level  
arrays of the same RAID type. Unlike dual-level arrays, the arrays  
in a RAID volume do not have to be of equal capacity. In direct  
contrast to dual-level arrays, the second-level arrays in a RAID  
volume are not striped together, instead they are connected end-to-  
end.  
Features  
Optimized Disk Utilization  
For simplicity the explanations of the various types of array above  
describe the arrays in terms of complete drives. Typically arrays  
use the same size drives, or if drives of varying capacities are used,  
the capacity used on each drive is limited to that of lowest capacity  
drive.  
For example, a RAID-1 constructed using one 18G and one 9G  
drive will only use half of the capacity of the larger drive and the  
array will be limited to 9G.  
Adaptecs Optimized Disk Utilization feature allows arrays to be  
created using portion of drives. These sections of drives are known  
as segments and are created automatically during the array  
creation process.  
Within a given array each segment will be the same size, but the  
segment size does not have to equal the capacity of the smallest  
drive.  
Any unused capacity on drives is known as available space, and  
can be used in another array or arrays.  
Adaptec RAID controllers use a small segment at the beginning of  
each drive connected to them to store information about the drives  
and arrays attached to the controller. This area is known as the  
RAID signature.  
Array Reconfiguration  
Adaptec RAID controllers support modifying existing arrays by  
expansion, migration from one array type to another and changing  
the stripe size.

See Chapter 3, Adaptec Storage Manager-Browser Edition, for  
instructions on modifying arrays.  
Some operating systems, for example Windows XP, Windows  
2000, Windows NT and Novell Netware, support Online Capacity  
Expansion (OCE). That is, on completion of an array expansion, the  
additional capacity can be used without rebooting the system.  
Refer to your operating system documentation for instructions on  
using the additional capacity.  
Drive Enclosures  
Adaptec RAID controllers support drive enclosures that include  
either SES or SAF-TE enclosure management hardware.  
Hot Spares  
A hot spare is a drive that is reserved to replace a failing drive in a  
redundant array. In the event of drive failure, the hot spare will  
replace the failing drive and the array will be rebuilt.  
Adaptec RAID controllers support two types of hot spares:  
Global—protects every array that the drive has enough  
available capacity to protect.  
Dedicated—protects only the array that it has been assigned to  
protect.

Introduction  
Automatic Rebuild On Replacement  
Adaptec RAID controllers support a feature known as Automatic  
rebuild on replacement. This may be useful in the event of a drive  
failure if no hot spare is available and the failing drive is in an SES  
or SAF-TE enabled drive enclosure.  
When this feature is enabled (default) a rebuild of any redundant  
array that the failed drive was a member of will be triggered  
automatically by simply removing the failure drive and replacing it  
with a new drive.  
SCSI Devices Supported  
In addition to SCSI hard disk drives, Adaptec RAID controllers  
support a wide range of SCSI devices, from CD-ROMs and tape  
drives to scanners and removable media drives.  
Supported Controllers  
The majority of this chapter and all the other documentation  
supplied with your controller describes the capabilities of the  
RAID controllers listed in the left column of Table 1-2. Adaptec  
Storage Manager-Browser Edition also supports other Adaptec  
RAID controllers provided the RAID management software  
supplied with those cards, Adaptec Storage Manager or Adaptec  
Storage Manager Pro is already installed on the system.

The Adaptec RAID Configuration Utility (ARC) is an embedded  
BIOS utility that includes an Array Configuration Utility (ACU)  
that allows the creation, configuration, and management of arrays.  
Also included are SCSISelect which supports changing SCSI device  
and controller settings, and Disk Utilities to low-level format or  
verify disk media.  
Adaptec also provides a standalone utility to create, configure, and  
manage arrays from an MS-DOS prompt. This utility is called  
Array Configuration Utility (ACU) for MS-DOS and it is described  
in the Adaptec SCSI RAID Software Reference Guide. This chapter  
describes only the functionality of the BIOS-based ACU.  
To run ARC, when prompted by the following message during the  
system boot process press Ctrl+A :

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
The Adaptec SCSI RAID Controller menu appears, presenting the  
following options:  
Array Configuration Utility  
SCSISelect Utility  
Disk Utilities  
To select an option from this menu or from any of the menus  
within ARC, move the cursor to the option with the Up/Down  
arrow keys and press Enter. In some cases, selecting an option  
displays another menu. You can return to the previous menu at  
any time by pressing Esc.  
The following sections discuss each of these menu options.  
Using the Array Configuration Utility  
The Array Configuration Utility (ACU) enables you to manage,  
create, and delete arrays from the controllers BIOS. You can also  
initialize and rescan drives.  
You can use the ACU to create a bootable array for the system. We  
recommend that you configure the system to boot from an array  
instead of from a single disk to take advantage of the redundancy  
and performance features of arrays. For details on creating a  
bootable array, see Deleting Arrays on page 2-4.  
Note: If you are changing the configuration of a system that is  
already in use on a network, log all users off the system and  
shut it down in an orderly manner before you start the ACU.  
Managing Arrays  
Use the Manage Arrays option to view array properties and  
members, make an array the boot array, manage failover  
assignments, and delete arrays. The following sections describe  
these operations in greater detail.  
Viewing Array Properties  
To view the properties of an existing array:

2 From the ARC menu, select Array Configuration Utility.  
3 From the ACU menu, select Manage Arrays.  
4 From the List of Arrays dialog box, select the array you want to  
view information on and press Enter.  
The Array Properties dialog box appears, showing detailed  
information on the array. The physical disks associated with the  
array are displayed here, except in the case of dual-level arrays  
(RAID 10 and RAID 50, for example). For dual-level arrays,  
highlight the displayed member and press Enter to display the  
second level. Press Enter again to display the physical disks  
associated with the array.  
Note: A failed drive is displayed in a different text color.  
5 Press Esc to return to the previous menu.  
Making an Array Bootable  
You can make an array bootable so that the system boots from the  
array instead of from a stand-alone (single) disk.  
To make an array bootable:  
1 At the BIOS prompt, press Ctrl+A.  
2 From the ARC menu, select Array Configuration Utility.  
3 From the ACU menu, select Manage Arrays.  
4 Select the array you want to make bootable and type Ctrl+B.  
This changes the selected arrays number to 00, making it the  
controllers boot array.  
5 Reboot the system.  
If you are booting from the controller, bear in mind the following:  
If the controller is not a boot device, you can disable its runtime  
BIOS, see page 2-11. When the BIOS is disabled it will not  
occupy any of the expansion ROM region of the systems  
memory map. This may be useful if there are several cards with  
an expansion ROM (BIOS) in the system.

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
You cannot make a non-00 array bootable if the array is in a  
build/ verify or reconfiguration process.  
Caution: The controller always uses the lowest numbered  
!
array as its bootable array. If you delete array 00 for any  
reason, the next lowest numbered array will become the  
bootable array. Use the Ctrl+B option to mark the correct  
array as the bootable array (by making it array 00).  
If you want to boot from a stand-alone (single) disk drive, first  
create a volume on that disk.  
The system BIOS provides additional tools to modify the boot  
order. For more information, refer to your system documentation.  
Deleting Arrays  
Caution: Back up the data on an array before you delete it. All  
data on the array is lost when you delete the array. Deleted  
!
arrays cannot be restored.  
To delete an existing array:  
1 At the BIOS prompt, press Ctrl+A.  
2 From the ARC menu, select Array Configuration Utility.  
3 From the ACU menu, select Manage Arrays.  
4 Select the array you wish to delete and press Delete.  
5 In the Array Properties dialog box, press Delete again and  
press Enter. The following prompt is displayed:  
Warning!! Deleting will erase all data from the  
array.  
Do you still want to continue? (Yes/No):  
6 Press Yes to delete the array or No to return to the previous  
menu. At the Array Properties dialog box, select Delete again  
and press Enter.

Creating Arrays  
Before creating arrays, make sure the disks for the array are  
connected and installed in your system (or enclosure). Note that  
any disks with MS-DOS partitions, disks with no usable space, or  
disks that are uninitialized appear dimmed and cannot be used for  
creating a new array. For information on how to initialize a disk  
drive, see page 2-9.  
To create an array:  
1 Shut down and reboot the system.  
2 At the BIOS prompt, press Ctrl+A.  
3 From the ARC menu, select Array Configuration Utility.  
4 From the ACU menu, select Create Array.  
5 Use the Left/Right arrow keys to select a channel.  
6 Select the disks for the new array and press Insert. ACU  
displays the largest usable space available for each disk. You  
can use available space from multiple disks for the new array.  
Note: Consult Table 2-1 on page 2-7 for the maximum  
number of drives that can be used for each RAID level.  
To deselect any disk, highlight the disk and press Delete.  
Note: ACU cannot reliably find disks or enclosures that  
were powered up after system power-up.  
7 Press Enter when all disks for the new array are selected. The  
Array Properties menu displays.  
If you install a controller into a system that has been powered  
down, on startup the BIOS will announce the detected  
configuration changes. If the controller does not consider these  
changes risky it will present a confirmation prompt and will auto-  
confirm if there has been no operator input in 30 seconds. If the  
controller considers that the changes are risky, you will be  
prompted for further action.

array size and select MB (megabytes), GB (gigabytes), or TB  
(terabytes) from the drop-down list. If the available space from  
the selected segments is greater than the size specified, the  
remaining space will be available for use in other arrays.

4 Select the desired stripe size. The allowable stripe sizes are 16,  
32, and 64 KB (the default). For RAID 50 arrays, 64 KB is the  
only stripe size supported by ACU. The default stripe size gives  
the best overall performance in most network environments.  
5 Specify whether you want to enable read caching for the array.  
This option should always be enabled to optimize performance,  
unless your application is doing completely random reads,  
which is unlikely.  
6 Specify if you want to enable write caching for the array.  
Note: By design, some controllers do not allow the use of  
write caching. In such cases, the controller will not activate  
write caching, regardless of the write cache setting. If this  
is the case a message will be displayed that tells you the  
settings have been recorded but have no effect.  
Write caching options (if supported) consist of the following:  
Enable when protected—If supported, enables the write  
cache only when a battery is present and the batterys charge  
status is OK.  
Enable always—If supported, enables the write cache even  
if no battery is present or the batterys charge status is not  
OK. Note that setting an arrays write cache property to  
Enablealwaysmight result in data loss or corruption if  
power to the controller is lost when no battery is present or  
the battery loses its charge.  
Disable—Disables use of the write cache.

Initializing Disk Drives  
If an installed disk does not appear in the disk selection list for  
creating a new array or if it appears grayed out, you may have to  
initialize it before you can use it as part of an array.  
Caution: Initializing a disk overwrites the partition table on  
!
the disk and makes any data on the disk inaccessible. If the  
drive is used in an array, you may not be able to use the array  
again. Do not initialize a disk that is part of a boot array. The  
boot array is lowest numbered array (normally 00) in the List  
of Arrays dialog box.  
See Viewing Array Properties on page 2-2 for information on  
determining which disks are associated with a particular  
array.  
To initialize drives:  
1 At the BIOS prompt, press Ctrl+A.  
2 From the ARC menu, select Array Configuration Utility.  
3 Select Initialize Drives.  
4 Use the Right/Left arrow keys to select a channel.  
5 Use the up and down arrow keys to highlight the disk you wish  
to initialize and press Insert.  
6 Repeat step 5 until all the drives to be initialized are selected.  
7 Press Enter.  
8 Read the warning message and ensure that you have selected  
the correct disk drives to initialize. Type Y to continue.

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
If Runtime BIOS is enabled and the BBS Support and Array-  
based BBS Support options are disabled, the controller  
BIOS is enabled and will post the lowest numbered array  
(typically 00) on the first controller found as a legacy Int13h  
bootable hard disk drive.  
The default is Enabled.  
Automatic rebuild on replacement — If enabled, this option  
lets you replace a failed drive in the same enclosure slot in a  
RAID 1, RAID 5, RAID 10 or RAID 50. Then the BIOS  
recognizes that the failed drive has been replaced, initializes  
the new disk, and immediately initiates a failover. Note that  
this option is supported only for disks in SAF-TE enclosures  
or backplanes.  
The default is Enabled.  
Array Background Consistency Check — If enabled, this  
option forces the controller to constantly check all portions  
of disks used by all arrays to see if the disks can return data  
from the blocks. On a fully-redundant RAID 5 with no bad  
segments, the controller repairs any data that cannot be  
read.  
The default is Disabled.  
BBS Support — If the Runtime BIOS option and this option  
are enabled and the Array-based BBS Support option is  
disabled, the lowest numbered array on each controller is  
posted as a BBS (BIOS Boot Specification) device.  
The default is Enabled.  
Array-based BBS Support — If Runtime BIOS, BBS  
Support and this option are all enabled, the lowest  
numbered three devices (typically 00, 01 and 02) on each  
controller in the system are posted as BBS devices.  
In a BBS-enabled system with two controllers installed, and  
at least three arrays on each controller, if Array based BBS  
support is enabled the “Hard drive boot order menu” will  
include six entries for arrays connected to the two RAID  
controllers.

5 The Select SCSI Channel menu is displayed. Select the  
appropriate channel from this menu.  
You can modify the following SCSI Channel Interface  
Definitions:  
Controller SCSI Channel ID — Sets the controllers SCSI  
ID. We recommend that you leave the controller set to SCSI  
ID 7, which gives it the highest priority on the SCSI channel.  
SCSI Parity Checking — Determines whether the controller  
verifies the accuracy of data transfer on the SCSI channel.  
You should disable SCSI Parity Checking on the controller  
and all SCSI devices if any SCSI device supported by the  
controller does not support SCSI parity; otherwise, leave it  
enabled. Most SCSI devices do support SCSI parity. If you  
are not sure whether a device supports SCSI parity, consult  
the documentation for the device.  
Controller SCSI Channel Termination — Sets termination  
on the controller card. We recommend that you leave the  
default setting of Auto Mode.  
SCSI Device Configuration — For information about these  
options, see the section, SCSI Device Configuration Options.  
SCSI Device Configuration Options  
The SCSI device settings allow you to configure certain parameters  
for each device on the SCSI channel. To configure settings for a  
specific device, you must know the SCSI ID assigned to that device.  
If you are not sure of the SCSI ID, see Using the Disk Utilities on  
page 2-15.  
Maximum Transfer Rate — Determines the maximum data  
transfer rate that the SCSI channel supports. The maximum  
effective data transfer rate is doubled when Initiate Wide  
Negotiation is set to Yes and 16-bit devices are attached. (Initiate  
Wide Negotiation has no effect with 8-bit devices.)  
Enable Disconnection — Determines whether the SCSI channel  
allows the SCSI device to disconnect from the SCSI channel  
(sometimes called Disconnect/ Reconnect or Reselection). This  
option should be enabled for maximum performance. The  
default is yes.

Using Adaptec RAID Configuration  
Initiate Wide Negotiation — Determines whether the SCSI  
channel attempts 16-bit data transfer instead of 8-bit data  
transfer. The effective data transfer rate is doubled when 16-bit  
data transfer is used. The default is yes.  
QAS — Determines whether QAS (Quick Arbitration and  
Selection) is used to eliminate overhead and speed up data  
transfers on the SCSI bus. The default is yes.  
Packetized — Determines whether SCSI packetization  
(encapsulation) is used to reduce overhead and speed data  
transfer. The packetized SCSI protocol provides a method for  
transferring command and status information at the maximum  
rate. The default is yes.  
Using the Disk Utilities  
The BIOS-based Disk Utilities enable you to low-level format or  
verify the disk media of your SCSI hard disks.  
To access the disk utilities:  
1 When you turn on or reboot your system, press Ctrl+A to access  
the Adaptec RAID Configuration (ARC) utilities when  
prompted by the following message:  
Press <Ctrl><A> for Adaptec RAID Configuration Utility  
2 If multiple controllers are installed, select the controller you  
want to configure and press Enter.  
3 From the ARC menu, select Disk Utilities.  
4 Select the desired channel and press Enter.  
After the option is selected, a list of all SCSI IDs and the devices  
at each ID is displayed. After selecting a specific ID and device,  
a small menu appears, displaying the following options:  
Format Disk—Performs a low-level format on a hard disk  
drive. Each hard disk drive must be low-level formatted  
before you can use your operating systems partitioning and  
file preparation utilities, such as MS-DOS Fdisk and Format.  
Most SCSI disk devices are preformatted at the factory and  
do not need to be formatted again. The Format Disk option  
is compatible with the vast majority of SCSI disk drives.

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
The controller should not be powered off or rebooted during  
a disk format. Doing so may render the disk unusable until  
the format is manually restarted and completed.  
Caution: A low-level format destroys all data on the  
!
drive. Be sure to back up your data before performing  
this operation. Once started, you cannot abort a low-  
level format.  
Verify Disk Media — Scans the media of a disk drive for  
defects. If the utility finds bad blocks on the media, it  
prompts you to reassign them. If you select yes, the utility  
remaps the recoverable defects and no longer uses those  
blocks. You can press Esc at any time to abort the utility.

About Adaptec Storage Manager  
Adaptec Storage Manager - Browser Edition is a web-based  
application that supports managing storage either locally (at the  
system in which the storage controller is installed), or remotely  
(from another system).  
Any system containing an Adaptec storage controller that has  
Windows or Linux and a supported browser installed can be  
managed locally. Supported browsers are:  
Windows  
Internet Explorer (IE) 5.0 or later  
Netscape 6 or later  
Linux  
Adaptec-supplied and installed version of Mozilla  
Netscape 6 or later  
These same Windows and Linux systems can also be managed  
remotely. This can be achieved in two ways:  
Installing Adaptec Storage Manager on the remote system.  
Directing the browser on the remote system to the system you  
want to manage.  
Note: If you want to manage from a Linux system it is  
recommended that you install Adaptec Storage Manager on  
the remote system and use the Adaptec-supplied version of  
Mozilla as the browser.  
For Unix and NetWare installations, Adaptec Storage Manager can  
only be used to manage the system remotely. Local management is  
supported using the CLI.  
The following explanation of the software architecture will help  
you understand the possible configurations and determine which  
one is most appropriate for your application. Installation  
instructions are included in the Adaptec SCSI RAID Installation  
Guide supplied on the same CD as this document.

Adaptec Storage Manager-Browser Edition  
Adaptec Storage Manager - Browser Edition consists of the three  
major components:  
A supported web browser, which should already be installed  
on the system.  
The Adaptec web service which supplies content displayed on  
the web browser.  
An Adaptec-supplied storage agent.  
For a locally managed system, all three components will be  
installed on the same system.  
To support the remote management configurations described  
below, all components must be installed on systems that have a  
TCP/ IP connection through which the other component(s) can be  
accessed.  
All communication uses Secure-HTTP (S-HTTP) or SSL protocols  
to encrypt all data transmitted and ensure security. Connection  
over an Ethernet network, a corporate WAN, or VPN are  
supported.  
Several remote management configurations are possible:  
The browser will always be on a remote system.  
The storage agent will always be installed on the system with  
the storage controller installed.  
The web service can be installed on the same remote system as  
the browser, the system with the storage controller installed on  
a third system.  
The storage agent is supplied for all supported operating systems,  
while the web service is available only for Windows and Linux. In  
order for Adaptec Storage Manager - Browser Edition to manage  
storage on a UNIX or NetWare system, the storage agent must  
communicate with the Adaptec web service on a separate  
Windows or Linux system.  
In this configuration, the Windows or Linux system can either be  
used to manage the RAID controller, or act as a server  
communicating with a supported browser on a third system.

Understanding Adaptec Storage Manager  
Shown below is an example of a typical Adaptec Storage Manager  
screen.  
.
Note: Depending on your operating system, browser, and  
color scheme you may notice some differences between this  
illustration and your screen.  
At the top of the Adaptec Storage Manager screen is the header  
frame. In this area is the name of the system that you are currently  
connected to and a number of buttons that perform various actions  
or open additional windows.  
The action buttons are Logout and Rescan. Selecting Logout will  
end your session and return you to the Login screen.  
Use the Rescan button to have Adaptec Storage Manager re-read  
the configuration of the system. Typically, when a rescan is  
required, it will occur automatically, for example, after an array is  
created.  
It is possible for the system configuration to change without  
Adaptec Storage Manager being notified. For example, drives  
inserted/ removed from a non-intelligent enclosure or an enclosure  
powered on after you logged in to Adaptec Storage Manager.  
The remaining buttons: Events, Options, Help, Properties, and  
Tasks open additional windows that provide more detailed  
information, allow you to perform actions or change settings on a  
specific aspect of your storage subsystem.

button to compress the  
information displayed for this controller. Controller information  
and device views are repeated for each additional Adaptec storage  
controller in the system.  
Select the controller by clicking anywhere on the controller  
information. When the controller is selected, the Events, Properties  
and Tasks buttons change from blue to amber, indicating that  
clicking any of them will bring up an additional window with  
information and options specific to this controller.

If you position the cursor over a device or button a pop-up tool tip  
appears. For buttons, the tips contain helpful information about the  
function of the button, while for devices they display additional  
information.  
Physical Devices  
The Physical Devices view displays information about the drives  
and enclosures attached to the Adaptec storage controller. The  
devices are shown organized by the channel that they are  
connected to and shown in numerical order.  
The display for each channel includes information on maximum  
speed capability, the number of the channel on the controller, and  
the number of devices found (excluding the SCSI controller).

At the top of the Physical Devices view, grouped to the right of  
View, are three view selection buttons  
. These buttons  
select how Adaptec Storage Manager displays the physical devices  
connected to this controller.  
Hot Spares  
Click the Hot Spare button  
to configure a drive or drives  
as hot spares. Hot spare drives are assigned to protect redundant  
arrays in the event of a drive failure. If a drive fails in a redundant  
array protected by a hot spare, the array will be rebuilt using the  
hot spare to replace the failing drive.  
A hot spare can be assigned to protect a single array or all the  
arrays on the controller.  
Changing How Drives are Displayed  
When Adaptec Storage Manager is loaded, the Physical Devices  
view will default to display a condensed view of the controller  
configuration which hides detailed information about the drives.  
More information is available by either positioning the mouse  
pointer over the device or clicking on the arrowhead to the left of a  
row of devices.  
The selected display mode button will appear in a lighter shade of  
blue than the other two buttons. The default display is the Text

Adaptec Storage Manager is loaded, the display is the same in all  
three modes.  
If you change the display mode by selecting one of the other view  
buttons, a yellow arrow will flash to the left of any devices where  
the current condensed display prevents Adaptec Storage Manager

displays a bar for each drive, with the largest capacity drive  
full-length and the other drives proportional to the drive capacity,  
relative to the largest drive.  
Any part of a drive used in an array is shown as a gray segment  
within the bar. Selecting any gray segment will highlight it in  
amber and, in the Logical Devices view, highlight the array of  
which this segment is a member.  
In either the Full Size Capacity View or the Relative Size Capacity  
View, a small portion at the end of the drive is shown in dark gray.  
The segment at the end of the drive may vary in size from drive to  
drive because, in addition to the RAID signature, the controller  
also limits the usable capacity of each drive to increments of 100  
MB.  
This is done because hard disk drives of apparently the same  
capacity from different manufacturers, or even different models  
from the same manufacturer, actually vary slightly in the true  
capacity available. Although, in normal operation this is not an  
issue, it can be when assigning hot spares or replacing a failed  
drive.  
If the controller used the maximum capacity of each drive and a  
hot spare or replacement drive was just a few megabytes smaller, it  
would not be able to replace the failed drive. By rounding drive  
capacities down to the nearest 100 MB, this possibility is effectively  
eliminated.

For detailed instructions on using these buttons, see the sections  
Creating Arrays on page 3-12, Deleting Arrays on page 3-17, and  
Modifying Arrays on page 3-17.  
The main area of the Logical Devices view is used to display the  
arrays on this controller. It defaults to a condensed view of top  
level arrays. For information on top and second-level arrays, refer  
to Supported RAID Types on page 1-2.  
Note: The Options button allows you to display second-level  
arrays if you prefer.  
In this condensed view, the RAID level of each device as well as  
whether it is protected by a hot spare, is visible.  
If a global hot spare exists, all arrays that the hot spare is large  
enough to protect will show as protected.  
In the expanded view, the icons for the arrays are arranged  
vertically and alongside them are the capacity, name and type of  
array.  
Selecting an array by clicking on it will highlight the following in  
amber:  
All the drives or segments that form the array in the Physical  
Devices view.

Logical Devices view.  
The Events, Properties, and Tasks buttons in the header frame.  
This indicates that selecting any of these three buttons will  
bring up an additional window with information and options  
specific to that array.  
Creating Arrays  
Before you use Adaptec Storage Manager to create an array, make  
sure that you understand the different types of arrays supported,  
as described in Supported RAID Types on page 1-2, and the type of  
arrays that are most appropriate for your application.  
Click Create to open the Create Array wizard. This wizard offers  
the following options:  
Create arrays using default settings.  
Expand the wizard by clicking on Advanced to see additional  
options and customize settings.  
Using the default settings will create an array of the largest  
possible capacity on the selected drives, use the default cache  
setting and, if appropriate, the default stripe size.  
To create an array using default settings:  
1 Open the Create Array wizard by clicking Create for the  
controller on which you want to create an array.  
2 Select the type of array you want to create in Step 1 of 3 in the  
Create Array wizard. Then click Next to move to Step 2 of 3.  
3 Click the drives you want to include in the array. Selected  
drives will display an amber check mark. When you have  
completed your selection click Next to move to Step 3.  
Note: The check marks will flash until you have selected  
enough drives to create this type of array.

4 Now you can accept the default name for the new array or enter  
one of your choice. The name you choose must be unique, and  
can be up to 15 standard ASCII characters in length.  
5 When you click Finish, the system will create the new array.  
Advanced Options  
Creating an array by clicking Advanced in the Create Array wizard  
follows the same basic process as the previous instructions, but at  
each step there are additional options for you to use.  
Step 1 of 3 in the Advanced area of the Create Array wizard offers  
the following additional options:  
Spanned Volumes and RAID Volumes—As described in  
Chapter 1, Introduction, a spanned volume concatenates segments  
from two or more drives to form a volume, while a RAID volume  
concatenates two or more arrays of the same type.  
Enable or Disable Write Caching—When write caching is  
enabled, the controller stores the data in cache memory on the  
controller and will accept another write to this array as soon as  
the data from the previous write is safely stored in the  
controllers memory.  
Since writing data to memory is much faster than writing it to  
the drives, enabling write caching can significantly improve  
performance. All data stored in the cache will be written to the  
drives when it is most efficient for the controller.  
On controllers fitted with a battery, the additional choice  
“Enable when protected by battery” is available. Choosing this  
option will enable write caching whenever the battery is  
operating correctly, and in the event of a power failure the  
battery will protect the data currently in cache.  
Caution: Default setting for write cache is enabled. This  
setting provides the best performance, but in the event of  
!
power failure there is a risk of data loss.  
3-13

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
Enable Or Disable Read Caching—When enabled, the  
controller will monitor read accesses to this array to try to  
predict where future reads may occur. If it detects a pattern, the  
data that seems most likely to be read next will be preloaded  
into the controllers cache memory. Since reading data from  
memory on the controller is much faster than reading it from  
the drives, this can have a significant impact on performance.  
This setting defaults to Enabled.  
Step 2 of 3 in the Advanced area of the Create Array wizard offers  
the following additional options:  
Limit Array Capacity—This option allows you to choose the  
capacity of the array you are creating. The default is to make the  
array the largest possible size with the drives selected. To create  
multiple arrays on a single set of drives you must use this  
option to limit the size of, at a minimum, the first array.  
For example, if you have two 18 GB drives, and you wish to use  
them to create two 9 GB RAID-1s, you would use this option to  
restrict the size of the first array you create.  
Note: A RAID-1 uses two drives to create a mirror; that is  
all data written to a RAID-1 is written to both drives  
limiting the capacity of the array to the capacity of the  
smaller drives.  
Stripe Size—For a RAID-0, 5, 10 or 50 where data is striped  
across multiple drives, stripe size determines how much data is  
written on each drive for a given stripe.  
Note: The default stripe size has been chosen to maximize  
performance for most typical applications. Changing the  
stripe size is likely to adversely affect performance.

Adaptec Storage Manager-Browser Edition  
For arrays which need to be initialized such as RAID-1 and  
RAID-5, advanced options allow you to select which method is  
used to initialize the array and set the priority of the initialization  
task.  
Step 3 in the Advanced area of the Create Array wizard offers the  
following initialization options:  
Build—For a RAID-1, the data from the primary or master  
drive is copied to the secondary or slave drive. For a RAID-5,  
correct parity is generated for the entire array.  
The advantages of building an array are that the array is  
immediately available for use, and that when the build is  
complete, the array operates at maximum performance. The  
disadvantages are that building takes some time, for a large  
array possibly many hours, and performance is impacted until  
the build completes.  
Clear—In this case, the contents of all the drives are cleared.  
The advantages of clearing an array are that the process is much  
faster than building and when completed, the array operates at  
maximum performance. The disadvantage is that the array is  
not accessible until the clear completes.  
Quick—In this case the array is immediately available. The  
advantage of quick initialization is that the array is immediately  
available with no on-going build. The disadvantage is that the  
write performance of a RAID-5 or RAID-50 initialized in this  
way is impacted until a Verify with fix Task is run on the array.  
Initialization Priority—This drop-down list allows you to  
adjust the priority of the initialization task. The default setting  
is high, and initialization will complete as fast as possible. The  
other options are medium and low. Depending on what other  
tasks are running on the controller, selecting either of these  
options may cause the initialization to take significantly longer.

About Adaptec Storage Manager Notifier  
Service  
Adaptec Storage Manager - Browser Edition includes a notifier  
service that enables controller events to be added to the system  
event log. This service can notify users, through e-mail, of  
controller events.  
When you install Adaptec Storage Manager on a system equipped  
with an Adaptec Advanced RAID controller, the notifier service is  
installed and configured to log all events to the system event log.  
The default installation has email event notification disabled.  
Notifier Service Event Levels

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
Introducing the Command Line Interface  
To configure and manage components running on the controller,  
Adaptec provides an easy-to-use graphical user interface (GUI)  
called Adaptec Storage Manager as well as a command line  
interface (CLI).  
The CLI provides an alternative to Adaptec Storage Manager.  
Through the CLI, you can perform most of the storage  
management tasks that you can perform with Adaptec Storage  
Manager and, in addition, some tasks not available in the GUI. To  
automate testing or array creation in a production environment,  
the CLI enables you to use CLI commands in Windows command  
scripts and UNIX/ Linux shell scripts.  
This chapter describes briefly some of the commands available in  
the CLI. For a full description of all the CLI commands see the  
Adaptec SCSI RAID Software Reference Guide.  
Accessing the Command Line Interface  
You can execute the command line interface (CLI):  
From the Windows XP, Windows 2000 or Windows NT Start  
button  
Note: The following procedure assumes that you accepted  
the default location for the software during installation.  
To access the CLI from the Windows XP(basic disk only),  
Windows 2000(basic disk only) or Windows NT Start button:  
1 Click the Start button and move the mouse cursor to  
Programs. Click on Programs.  
2 Move the mouse cursor to SMBE. The Adaptec program  
group will display.  
3 Move the mouse cursor to the CLI icon. Click on CLI.  
From the NetWare server console  
To access the CLI from the NetWare server console, type  
aaccliat the prompt. When the system displays the CLI>  
prompt, which indicates that you can now use CLI commands.

Using the Command Line Interface  
From the UNIX/ Linux prompt  
To access the CLI from the UNIX/ Linux prompt, display a  
window and type aaccliin any directory. When the system  
displays the CLI> prompt, you can use CLI commands. For the  
commands to work in any directory, the path in the startup file  
(.loginor .cshrc) must include the directory where the  
software is installed. See your UNIX/ Linux documentation for  
information on setting up directory paths in the .loginand  
.cshrcfiles.  
Terminology

4-4  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
Using the Command Line Interface  
Before you can work with arrays, you must have previously  
opened the controller. In addition, you must have initialized your  
disk(s) to prepare for array operations.  
The minimum size of an array is 10 MB.  
Before creating any array, use the disk show spacecommand  
to display information about your disks. In the following example,  
the Usage column indicates Free for each disk, which means that  
the space on each disk consists of available space.  
AAC0> disk show space  
Executing: disk show space

After creating an array, use the container listcommand to  
display information about the array. In the following example, the  
Num Label column indicates the array ID 0 and the array label  
Venus. The Type column indicates a Volume set. The Total Size  
column indicates that the array is 100 MB.

Creating a Volume Set  
To create a volume set, use the container create volume  
command. In the following example, the volume set 0 is created on  
SCSI device (2,01,0) from 100MB (megabytes) of available space.  
The arrays raw cache is enabled, and the label Venus is specified.  
AAC0> container create volume /cache=TRUE /label=Venus  
((2,01,0), 100M)  
Executing: container create volume /cache=TRUE /  
label=Venus ((CHANNEL=2,ID=1,LUN=0),104,857,600)

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
Creating a RAID 0  
When creating a RAID 0, you need to determine the stripe size that  
is most suitable for your environment. The stripe sizeattribute  
indicates the number of bytes in a stripe, the amount of data  
written to a segment before the I/ O data stream switches to the  
next segment in the stripe. The stripe size can be 16 KB, 32 KB, or  
64 KB. The default stripe size is 32 KB. Note that you can use the  
container reconfigurecommand at a later time to change the  
stripe size.  
To create a RAID 0, use the container create stripe  
command. In the following example, the stripe set 0 is created on  
SCSI device (2,01,0) from 100 MB of available space. The arrays  
raw cache is enabled, and the label Mars is specified.  
AAC0> container create stripe /cache=TRUE /label=Mars  
((2,01,0), 100M)  
Executing: container create stripe /cache=TRUE /  
label="Mars" ((CHANNEL=2,ID=1,LUN=0),104,857,600 )  
container 0 created  
Creating a RAID 1  
To create a RAID 1, use the container create new_mirror  
command. In the following example, a RAID 1 is created on SCSI  
devices (2,2,0), and (2,3,0) using 100 M of available space from each  
SCSI device.  
AAC0> container create new_mirror ((2,2,0), 100M)  
(2,3,0)  
Executing: container create new_mirror  
((CHANNEL=2,ID=2,LUN=0),104,857,600 )  
(CHANNEL=2,ID=3,LUN=0)

Using the Command Line Interface  
Creating a RAID 5  
When creating a RAID 5, you need to determine the stripe size that  
is most suitable for your environment. See Creating a RAID 0 for  
more information about determining the appropriate stripe size for  
your environment.  
To recreate the data of a failed disk in a RAID 5, you use a form of  
redundancy called parity. When you set up parity, you initialize  
the parity stripes by using a scrubbing switch (/scrub=TRUE).  
Parity is set up in the background, and the disks are available  
immediately.  
The /scrubswitch is not available in UNIX/ Linux. For UNIX/  
Linux, the RAID 5 is always created by building.  
To create a RAID 5, use the container create raid5  
command. In the following example, a RAID 5 is created on SCSI  
devices (2,1,0), (2,2,0), and (2,3,0) using 100 M of available space  
from each SCSI device. The /stripe_size switch specifies that each  
stripe is 64 K in size.  
AAC0> container create raid5 /stripe_size=64K ((2,1,0),  
100M) (2,2,0) (2,3,0)  
Executing: container create raid5 /stripe_size=65,536  
((CHANNEL=2,ID=1,LUN=0),104,857,600)  
(CHANNEL=2,ID=2,LUN=0) (CHANNEL=2,ID=3,LUN=0)  
Deleting Arrays  
To delete an array, use the container deletecommand. In the  
following example, array 0 is deleted.  
AAC0> container delete 0  
Executing: container delete 0  
After running the container deletecommand, use the  
container listcommand to verify that the array was deleted.  
In the following example, no arrays are found on the controller.  
AAC0> container list  
Executing: container list  
No containers found.

Adaptec SCSI RAID 2120S/2200S Software User’s Guide  
Enabling Spares  
A spare disk (also called a “hot spare”) is a disk that you configure  
to recover data from a failed segment/ disk in a redundant array.  
To assign one or more spare disks for a single array, use the  
container set failovercommand. To assign one or more  
spare disks for all arrays, use the container set  
global_failovercommand. The main characteristic of these  
commands is that you must “manually” assign the spare disk to  
one or more arrays. In fact, you might consider the previously  
described spare mechanism as “manually set spare.”  
Note: RAID 1, 5 10 and 50 use the spare assignment if a disk  
fails. (RAID 1, 5, 10 and 50 are often referred to as redundant  
arrays).  
Automatic rebuild on replacement allows you to replace a failed  
disk with a replacement disk. The controller automatically assigns  
the disk you insert as a hotspare without your having to first assign  
it manually using the container set failoveror  
container set global_failovercommand.  
See the Adaptec SCSI RAID Software Reference Guide for more  
information on the containersetfailoverand container  
setglobal_failovercommands.  
Caution: The controller deletes any data on the replacement  
!
disk when automatic rebuild on replacement is enabled and  
you remove the failed disk and insert the replacement disk in  
the failed disks slot.  
Note: The automatic spare feature works only with disks that  
reside in an SAF-TE or SES enabled enclosure.  
Through the CLI, you can:  
Display a controllers automatic rebuild on replacement status  
Enable automatic rebuild on replacement

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Using the Command Line Interface  
To display a controllers automatic rebuild on replacement status,  
use the controller show automatic_failovercommand.  
In the following example, rebuild on replacement is indicated as  
DISABLED.  
AAC0> controller show automatic_failover  
Executing: controller show automatic_failover  
Automatic failover DISABLED  
To enable automatic spare, use the controller set  
automatic_failovercommand with the /failover switch, as in  
the following example:  
AAC0> controller set automatic_failover  
/failover_enabled=TRUE  
Executing: controller set automatic_failover  
/failover_enabled=TRUE  
After running the controller set automatic_failover  
command, use the controller show automatic_failover  
command to verify that automatic rebuild on replacement has been  
enabled. If necessary, you can now replace a failed disk with a  
replacement disk.  
Displaying Controller Information

Container (Array) Commands  
Before working with arrays, you must have previously opened the  
controller. In addition, you must have initialized your disk(s) to  
prepare for array operations.  
The following commands are used to display, create, and manage  
arrays.  
Command Summary:  
container add_level {container}  
Creates a multilevel volume array which contains the array  
as its only element.  
Parameters  
{container}—ID of the array to convert to a multilevel  
volume.  
container clear [/always{=boolean}]  
[/wait{=boolean}] {container}  
Clears the array.  
Parameters  
{container}—ID of the array to clear.  
Switches  
/always—Specifies whether to clear the array even if it has  
data on it. The default is FALSE, meaning that the command  
clears the array only if it has no data on it. All user files must  
be closed; the /alwaysswitch cannot override this  
restriction.  
/wait—Specifies whether to clear the array synchronously  
and not return the command prompt until the clear array  
task completes. The default is FALSE, meaning that the  
command clears the array asynchronously and the  
command prompt returns immediately.
