In this Document
Applies to:
SPARC T4-1 - Version Not Applicable and later
SPARC T3-1 - Version Not Applicable and later
Information in this document applies to any platform.
Purpose
Lists basic sas2ircu commands to monitor/create internal RAID volumes on T3/4 series systems.
Details
The T3 & T4 series systems no longer can access the raidctl utility that was included in Solaris. This tool must be downloaded & placed onto the customer's system from URL:
http://www.lsi.com/support/sun/
From this URL, choose left column link: SPARC T3 Series Platform Support , & then choose the proper server's download. It is recommended to rename this utility to sas2ircu (removing the version indication) & place this utility in /usr/sbin. Explorer will eventually be able to use this utility to obtain internal RAID volume information. Help information can be obtained by entering the command with no parameters:

SAS2IRCU: No command specified.
sas2ircu <controller #> <command> <parameters> ...
where <controller #> is:
Number between 0 and 255
where <command> is:
DISPLAY - display controller, volume and physical device info
LIST - Lists all available LSI adapters (does not need ctlr #>
CREATE - create an IR volume
DELETE - Delete entire RAID configuration on the selected controller
DELETEVOLUME - Delete a specific RAID Volume on the selected controller
HOTSPARE - make drive a hot spare
STATUS - display current volume status info
CONSTCHK - Start Consistency Check operation on the specified IR Volume
ACTIVATE - Activate an Inactive IR volume
LOCATE - Locate a disk drive on an enclosure
LOGIR - Upload or Clear IR Log data
BOOTIR - Select an IR Boot Volume as primary boot device
BOOTENCL - Select an Enclosure/Bay as primary boot device
where <parameters> are:
Command specific values; enter "sas2ircu <controller #> <command>"
to get command specific help
Obtain info about existing Volumes:
Information provided in the T3 server's admin guide should indicate which controller(s) can be configured with disks. In the examples below, a Netra T3-1 has all disks on controller 1 (first parameter). Volume status can be obtained by the following command:
# sas2ircu 1 status

Create a mirror volume:
The following example indicates how to create a RAID volume with 2 unused disks (slots 2 & 3 from above). First, check the status of the controller:
# ./sas2ircu-6.250.02.00 1 status
LSI Corporation SAS2 IR Configuration Utility.
Version 6.250.02.00 (2010.06.30)
Copyright (c) 2009-2010 LSI Corporation. All rights reserved.
SAS2IRCU: there are no IR volumes on the controller!
SAS2IRCU: Error executing command STATUS.
Next, create a mirror (RAID 1) on controller 1, slots 2 & 3 as indicated in the "sas2ircu display" command above:
# ./sas2ircu-6.250.02.00 1 create raid1 MAX 1:2 1:3
