SAS-2 Integrated RAID Configuration Utility (SAS2IRCU) User Guide 
November 2012
Commands
The following restrictions and defaults apply when you create Integrated RAID volumes and hot spare disks:
 All disks that are part of a volume, including hot spares for that volume, must be connected to the same LSI SAS-2
controller.
 The supported RAID levels are RAID 0, RAID 1, RAID 1E, or RAID 10.
 The maximum and minimum disk drives per RAID level are as follows:
— RAID 0: Max = 10; Min = 2.
— RAID 1: Max = 2; Min = 2.
— RAID 1E: Max = 10; Min = 3.
— RAID 10: Max = 10; Min = 3.
 You can create a maximum of two Integrated RAID volumes per LSI SAS-2 controller.
 You can create one or two hot spare disks per controller. For more information about hot spare disks, see
Section
3.6 , HOTSPARE .
 Each LSI SAS-2 controller supports a maximum of 14 physical disks for the RAID volumes and hot spares.
 SAS2IRCU does not allow you to create an Integrated RAID volume that combines SAS and SATA hard disk drives.
 SAS2IRCU does not allow you to create an Integrated RAID volume that combines solid-state drives (SSDs) and
hard disk drives.
 SAS2IRCU supports disk drives with 512-byte sectors and disk drives with 4-KB sectors. However, an Integrated
RAID volume must use all 512-byte-sector drives or all 4-KB-sector drives. You cannot combine the two types of
drives in a single Integrated RAID volume.
3.2.1 Command Line
sas2ircu <controller_#> create <volume_type> <size> {<Enclosure:Bay>}
[VolumeName] [noprompt]
3.2.2 Parameters

<controller_#> – The index of the controller for the newly created volume.
 <volume_type> – Volume type for the new volume. Valid values are RAID0, RAID1, RAID10, or RAID1E.
 <size> – Size of the RAID volume in MB, or MAX for the maximum size available.
 <Enclosure:Bay> – The Enclosure:Bay value of the disk drive for the new RAID volume. Determine these
values from the output of the DISPLAY command. DOS does not support addressing by Enclosure:Bay.

[VolumeName] – A user-specified string to identify the volume.
 [noprompt] – This optional parameter prevents warnings and prompts from appearing while the command is
running.
3.2.3 Program Return Value
0x00 SUCCESS: Command completed successfully.
0x01 FAILURE: Bad command-line arguments or operational failure.
0x02 ADAPTER_NOT_FOUND: Cannot find specified adapter.
NOTE Some operating systems do not fully support 4-KB-sector drives. Refer to the documentation for
the operating system you are using.
