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 /pci@8000/pci@4/pci@0/pci@0/scsi@0 FCode Version 1.00.56, MPT Version 2.00, Firmware Version 13.00.54.00 Target 11e Volume 0 Unit 0 Disk LSI Logical Volume 3000 10485760 Blocks, 5368 MB VolumeDeviceName 3eb2fdbd4c32058f VolumeWWID 0eb2fdbd4c32058f 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.
{0} ok select /pci@8000/pci@4/pci@0/pci@0/scsi@0 {0} ok show-volumes Volume 0 Target 11e Type RAID1 (Mirroring) Name raid1-volume WWID 0eb2fdbd4c32058f WWID of the RAID volume Optimal Enabled Data Scrub In Progress 2 Members 1169920000 Blocks, 598 GB Disk 1 Primary Optimal Target a TOSHIBA MBF2300RC 3706 Disk 0 Secondary Optimal Target b TOSHIBA MBF2300RC 3706 {0} ok |
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 |
