sas2ircu Might Fail to Create a RAID Volume (15788910)

When you use the sas2ircu command within Oracle Solaris to create a RAID volume, the command might report that volume creation has failed. For example:

# ./sas2ircu 0 create raid0 max 1:0 1:1 1:2 my-RAID0

You are about to create an IR volume.
 
WARNING: Proceeding with this operation may cause data loss or data
 corruption. Are you sure you want to proceed (YES/NO)? yes
 
WARNING: This is your last chance to abort this operation. Do you wish 
 to abort (YES/NO)? no 
Please wait, may take up to a minute...

SAS2IRCU: Volume creation failed. 
SAS2IRCU: Error executing command CREATE 
# 

If you retype the sas2ircu command at the Oracle Solaris prompt, the command will fail. The sas2ircu command will state that the wrong number of disks have been provided, since they had already been committed to a volume. For example:

# ./sas2ircu 0 create raid0 max 1:0 1:1 1:2 my-RAID0

SAS2IRCU: Number of drives specified is higher than number of drives 
available to create a RAID volume! 
SAS2IRCU: Error executing command CREATE. 
# 

After the initial failure of the sas2ircu command, other disk utility commands, such as format, might show disk members of the volume marked as drive not available. The format command might appear to hang and will require that you type Ctrl-C to abort the command. For example:

# format
Searching for disks...done

Ctrl-C

Workaround: Reboot the system to restore the volume to a working state.

# reboot

Alternatively, you can use one of the other available methods to create the volume, instead of the sas2ircu command.

  • Create a volume under Oracle Solaris with the raidconfig command. The Oracle Hardware Management Pack includes the raidconfig command.

    You can download the Oracle Hardware Management Pack software at:

    https://support.oracle.com

    You can read and download documentation for the version of Oracle Hardware Management Pack you are using at:

    http://www.oracle.com/goto/OHMP/docs

  • Create a volume at the OpenBoot prompt with the FCode-based RAID utility commands.

    For instructions on using the FCode-based RAID utility commands, refer to the SPARC and Netra SPARC T5 Series Servers Administration Guide.
