SAS BIOS features
The SAS BIOS is the bootable ROM code that manages SAS hardware resources. It is specific to a family
of SAS controllers and processors. The SAS BIOS integrates with a standard system BIOS, extending the
standard disk-service routine provided through INT13h.
During initialization, the SAS BIOS determines if the system BIOS has already installed other hard disks,
such as an IDE drive. If other drives are already installed, the SAS BIOS maps any SAS or SATA drives it
finds behind these drives. Otherwise, the SAS BIOS installs drives starting with the system boot drive, and
then the system boots from a drive controlled by the SAS BIOS.
The SAS BIOS supports the BIOS boot specification (BBS). If the system supports the BBS, use the system
BIOS setup menu to select the boot order and drive order. In the system BIOS setup, the Boot Connection
Devices menu lists the available boot options. Select the device and boot order. Exit to continue the boot
process.
Starting the SAS BIOS configuration utility
SAS BIOS 6.xx, with the SAS BIOS configuration utility, enables you to change the default configuration
of SAS host adapters. The default configuration might need to be changed if the adapter conflicts with
other devices or if system performance needs optimization.
The version number of the SAS BIOS appears during boot. If the configuration utility is available, the
following message also appears:
Press F8 to start LSI Logic Configuration Utility...
The exact key sequence required to start the utility might vary for different versions of the utility.
This message remains on the screen for 5 seconds, giving you time to start the utility. If you start the utility,
the screen displays the following message:
Please wait, invoking LSI Logic Configuration Utility...
After a pause, the SAS BIOS configuration utility opens.
The following messages might appear during the boot process:
•Adapter removed from boot order!
This message appears when an adapter was removed from the system or was relocated behind a
PCI bridge.
•Adapter configuration may have changed, reconfiguration is suggested!

SAS BIOS configuration utility 10
This message appears when the information in the NVRAM is invalid.
•Updating adapter list!
This message appears when fewer than four adapters are in the boot-order list, and more adapters
exist than are shown.
The SAS BIOS configuration utility can detect devices that the SAS BIOS cannot control (for example, tape
drives and scanners). However, the configuration utility can still be used to modify certain parameters for
these devices.
Configuration utility screens
All SAS BIOS configuration utility screens contain the following areas, starting at the top of the screen:
•Header—Identifies the utility and version number.

Performing configuration tasks
Creating a RAID 0 volume
In a RAID 0 volume, data is striped across multiple disk drives, combining the drives into one logical
volume. This procedure maximizes storage capacity and performance.
When selecting drives for the RAID 0 volume, remember the following limitations:
•Every drive in the volume must be the same type, either SAS or SATA.
•Each drive must have 512-byte blocks.
•Drives with removable media are not supported.
•The volume must have at least two drives but no more than eight drives.
•RAID 0 volumes cannot have hot-spare drives, so data is unprotected against drive failure.
To create a RAID 0 volume:
1. On the Adapter List screen, select an adapter.
2. On the Adapter Properties screen, select RAID Properties.
oIf the adapter has a configured volume, the View Array screen appears. Press the Ckey to create
a new volume.
oIf the adapter does not yet have a configured volume, the Select New Array Type screen
appears.
3. On the Select New Array Type screen, select Create RAID 0 Volume.
The Create New Array screen appears. This screen lists the drives that you can use to create the
RAID 0 volume.
4. Identify a drive that you want to use in the RAID volume, and then move the cursor to the RAID Disk
column for that drive.

SAS BIOS configuration utility 18
5. Press the +key, –key, or spacebar.
The No in the RAID Disk field changes to Yes, and the value in the Array Size field changes to
reflect the new size of the volume.
6. Repeat steps 4 and 5 for each drive that you want to use in the RAID volume.
7. Confirm that the configuration of the RAID volume is exactly as you want it. You cannot change the
configuration after the utility has created the array.
8. Press the Ckey.
9. Select Save changes.
The configuration utility pauses while it creates the array. When array creation is complete, the
Adapter Properties screen appears.
10. (Optional) To set this RAID 0 volume as the boot volume, select the SAS Topology option on the
Adapter Properties screen and then, on the SAS Topology screen, set the boot volume. For more
information, see "Selecting a boot disk (on page 21)."
Creating a RAID 1 volume
In a RAID 1 volume, data is mirrored from one disk drive to another one. This procedure increases
reliability by providing protection against the failure of a single drive.
You can provide additional protection by configuring a RAID 1 volume with a hot spare. If a drive fails in
such a configuration, data that was on the failed drive is rebuilt to the hot spare from the mirrored drive.
When selecting drives for the RAID 1 volume, remember the following limitations:
•Every drive in the volume must be the same type, either SAS or SATA.
•Each drive must have 512-byte blocks.
•Drives with removable media are not supported.
•A RAID 1 volume must have two drives (three if you use a hot spare).
To create a RAID 1 volume:
1. On the Adapter List screen, select an adapter.
2. On the Adapter Properties screen, select RAID Properties.
oIf the adapter has a configured volume, the View Array screen appears. Press the Ckey to create
a new volume.
oIf the adapter does not yet have a configured volume, the Select New Array Type screen
appears.
3. On the Select New Array Type screen, select Create RAID 1 Volume.
The Create New Array screen appears. This screen lists the drives that you can use to create the
RAID 1 volume.
4. Identify a drive that you want to use in the RAID volume, and then move the cursor to the RAID Disk
column for that drive.
5. Press the +key, –key, or spacebar.
The No in the RAID Disk field changes to Yes, and the value in the Array Size field changes to
reflect the new size of the volume.
When you add the first drive, the utility prompts you to keep any existing data on that drive or
overwrite it.

SAS BIOS configuration utility 19
oTo keep existing data, press the Mkey.
oTo overwrite existing data, press the Dkey.
6. (Optional) To add a hot spare, move the cursor to the Hot Spr column and press the +key, –key, or
spacebar.
An adapter can have only one hot spare, which generally acts as a global hot spare for all volumes
on the adapter. However, if you configure an adapter with one SAS RAID 1 volume, one SATA RAID
1 volume, and a SAS drive as the hot spare, the hot spare is available only for the SAS volume.
7. Press the Ckey.
8. Select Save Changes.
The configuration utility pauses while it creates the array. When array creation is complete, the utility
displays the Adapter Properties screen.
9. (Optional) To set this RAID 1 volume as the boot volume, select the SAS Topology option on the
Adapter Properties screen and then, on the SAS Topology screen, set the boot volume. For more
information, see "Selecting a boot disk (on page 21)."
Viewing RAID volume properties
1. On the Adapter List screen, select an adapter.
2. On the Adapter Properties screen, select RAID Properties. The View Array screen is displayed,
showing the properties of the first volume on the adapter.
3. If the adapter has more than one volume configured, view the properties of the next array by
pressing Alt+N.
Managing an array
1. On the Adapter List screen, select an adapter.
2. On the Adapter Properties screen, select RAID Properties.
3. On the View Array screen, select Manage Array.
The Manage Array screen appears, displaying the following options:
oManage Hot Spare ("Managing hot spares" on page 19)
oSynchronize Array ("Synchronizing an array" on page 20)
oActivate Array ("Activating an array" on page 20)
oDelete Array ("Deleting an array" on page 20)
4. Select an option from the list, and follow the prompts that are presented for that option on the screen
that appears.
Managing hot spares
The Manage Hot Spare screen enables you to add hot spares to RAID 1 volumes and to remove hot
spares. An adapter can have only one hot spare, which generally acts as a global hot spare for all RAID
1 volumes on the adapter. However, if you configure an adapter with one SAS RAID 1 volume, one SATA
RAID 1 volume, and a SAS drive as the hot spare, the hot spare is available only for the SAS volume.
To add or remove a hot spare:
1. On the Manage Array screen, select Manage Hot Spare.

SAS BIOS configuration utility 20
2. Perform one of the following actions:
oTo remove a hot spare, move the cursor to the hot spare and then press the +key, –key, or
spacebar.
oTo add a hot spare, move the cursor to a suitable disk in the list and then press the +key, -key,
or space bar. (A drive can be used as a hot spare only if it is a valid RAID drive. For information
about the limitations, see "Creating a RAID 1 volume (on page 18)".)
3. Press the Ckey.
4. Select Save changes.
5. Exit the Manage Hot Spare screen to enable the changes.
The configuration utility pauses while the hot-spare configuration is changed.
Synchronizing an array
When a RAID 1 volume is synchronized, the data on the secondary drive of the mirror is updated by
copying changed data from the primary drive.
To start a synchronization, select Synchronize Array on the Manage Array screen, and then press Y. (To
cancel a synchronization, press N.)
Activating an array
An array becomes inactive if, for example, it is removed from one controller or computer and moved to
another one. The Activate Array option enables an inactive array that has been added to a system to be
reactivated. This option is only available when the selected array is currently inactive.
To activate an array, select Activate Array on the Manage Array screen, and then press Y. (To cancel the
activation, press N.)
After a pause the array becomes active.
Deleting an array
CAUTION: To avoid loss of data, back up all data before deleting the array.
To delete an array, select Delete Array on the Manage Array screen, and then press Y. (To cancel the
deletion, press N).
When a volume has been deleted, it cannot be recovered. When a RAID 1 volume is deleted, the data is
preserved on the primary disk. The master boot records of other disks in the array are deleted. For other
RAID types, the master boot records of all disks are deleted.
Moving an array
When you remove an array and install it into another system (or reinstall it into the same system), the
array is initially inactive and must be reactivated ("Activating an array" on page 20). If the moved or
reinstalled volume is the boot volume, the system displays a non-system disk message when it is restarted
because it cannot boot until the array is reactivated. To get the system to boot:
1. Restart the system.
