SHOW DISKS displays the following information on
all available physical disks:
- Disk number
- Enclosure bus number and ID
- Disk size
- UNIT created on the disk
- Disks assigned as spares
Note:
- SHOW DISK <disk_n> can be used to see
information of a particular disk,
where disk_n is the disk number. Disks
are identified by their corresponding
SCSI bus and SCSI IDs for all the controllers.
For SAS controllers, internally connected
disks are numbered based on their bay numbers
and externally connected disks are numbered
based on combination of their box number
and bay number as
"disk_n" = box Number *100 + bay number".
Examples
For SAS controllers, the output of
SHOW DISK command is as follows:

For all other controllers, the output of
SHOW DISK command is as follows:
