14.2.12 Specifying a Hardware RAID Volume as a Boot Device
This section describes how to specify a hardware RAID volume as a boot-device.
For details on specifying a boot device, see "Appendix I How to Specify the Boot Device."
  1. Select the device and display its volume information.
    Check the WWID of the RAID volume.
  1. The following is an example of the SPARC M10. Check the WWID of the RAID volume.
{0} ok select /pci@8000/pci@4/pci@0/pci@0/scsi@0
{0} ok show-volumes
Volume 0 Target 11e Type RAID1 (Mirroring)

  1. Specify the RAID volume that was confirmed in step 1 as the boot device.
    Follow the rules below when specifying the RAID volume.
    a. Replace the number "0" at the beginning of the WWID of the RAID volume with "3".
    Since the WWID of the RAID volume that was confirmed in Step 1 is "0c233a838262c6c5," it becomes "3c233a838262c6c5."

    b. To the WWID of the RAID volume in step 2a, (the one in which you replaced a digit), add "disk@w" to the beginning of it, and append ",0:a" to its end.

    c. Specify the full pathname of the RAID boot device as the argument to the setenv boot-device command below. The full pathname is the device path selected in step 1, "/pci@8000/pci@4/pci@0/pci@0/scsi@0/", followed by the RAID boot device name from step 2b, "disk@w3c233a838262c6c5,0:a".
{0} ok setenv boot-device /pci@8000/pci@4/pci@0/pci@0/scsi@0/disk@w3c233a838262c6c5,0:a
