I.5 Method of Specification With a Volume Device Name


I.5 Method of Specification With a Volume Device Name
This specification method uses the volume device name of a built-in hardware RAID to specify the boot device. The volume device name is assigned to each volume configured in the RAID.
You can use this method when specifying a built-in hardware RAID as a boot device.
To find the volume device name of the boot disk, execute the probe-scsi-all command on OpenBoot PROM, and check the VolumeDeviceName value.
{0} ok probe-scsi-all

Volume device name
In XCP 2070 and earlier, VolumeDeviceName may not be output. In this case, execute the show-volumes command, which will output a volume WWID. Replace the first WWID character with "3" to get the volume device name.

Boot Device Notation
<Device path of the SAS controller>/disk@wXXXXXXXX,Y:Z
Here, specify the volume device name for the XXXXXXXX after "disk@w". Furthermore, specify the logical unit number (LUN) and slice number of the built-in hardware RAID, for Y and Z, respectively.
Note - You can omit the logical unit number (LUN) and slice number. If omitted, LUN "0" and slice number "a" are assumed specified. If a built-in hardware RAID is used as a boot device, LUN "0" and slice number "a" are specified, so these numbers have the same values as when omitted. Therefore, in the use example, the notation is in a form that omits the LUN and slice number.
Use Example
Specify the following, where "3eb2fdbd4c32058f" is the volume device name of the boot device.
{0} ok boot /pci@8000/pci@4/pci@0/pci@0/scsi@0/disk@w3eb2fdbd4c32058f
