SAS2 BIOS Configuration Utility
The LSI™ SAS2 BIOS Configuration Utility is used to configure one or two Integrated
Mirroring, Integrated Mirroring and Striping, and Integrated Mirroring Enhanced volumes
on each SAS2 controller.
The utilility can also be used to configure one mirrored volume and one Integrated
Striping volume on the same controller, up to a maximum of fourteen physical disk
drives for the two volumes. This includes up to two optional hot spare disks for the
mirrored volume(s).
7-1 Starting the LSI SAS2 BIOS Configuration Utility
Use the following procedure for bringing up the SAS2 BIOS Configuration Utility:
1. Boot the system.
2. Start the SAS2 BIOS Configuration Utility by pressing C

Please wait, invoking SAS Configuration Utility...
If the message below appears
WARNING: You cannot combine both SATA and SAS physical disks in the same
volume. All disks in the same volume must be either SATA (with extended
command set support) or SAS (with SMART support).
However you can create one volume made up of SAS disks and one volume of
SATA disks on the same controller.
NOTE: You must use 512-byte block disks that are not removable media for the
LSI SAS2 BIOS Configuration Utility.
NOTE: You need two disks for Integrated Mirroring volumes, three to ten disks
for Integrated Mirroring Enhanced volumes and four to ten even numbered
disks for Integrated Mirroring and Striping volumes.
NOTE: It is recommended that you create global hot spare disks for all mirrored
volumes for your data protection. Failed mirrored volumes are rebuilt by the
Integrated RAID firmware using these global hot spares to make the data safe.
If one of a pair of mirrored volumes fails on a SAS2 controller, then either of
them can use the global hot spares.
