"HP IR volume" on your server is a HW raid configured, raid1 configuration, to the OS level is only one device as disk presented,
and that is a HP- IR volume.

IR = integrated RAID (mirror), built on the internal SAS controller, try

# sasmgr get_info -D /dev/sasd0 -q raid

to see the details.

Hi vasnath,

If Integrated RAID volume is configured on rx2660, rx3600, and rx6600 from the controller and you perform one of the following actions:

â Update the adapter firmware offline using sasflash.efi.
â Boot to an HP-UX or Ignite-UX disk containing the sasd driver from one of the following
releases, which download firmware version 1.23.33 to the adapter during boot:
â ¦B.11.23.0712
â ¦B.11.31.0712
