Displaying Disk Physical Locations

Language:

To display physical locations of disks, use the croinfo command which provides information about the chassis, receptacle, and occupant relative to the specific disk.

$ croinfo
D:devchassis-path                 t:occupant-type   c:occupant-compdev
-----------------------------------------------------  ------------------
/dev/chassis/SYS/HDD0/disk        disk              c2t0d0
/dev/chassis/SYS/HDD1/disk        disk              c2t1d0
/dev/chassis/SYS/HDD2/disk        disk              c2t2d0

You can use different options with the croinfo command to display information only about a specific disk.

croinfo –c disk displays information only about a specific disk. disk refers to the component listed under the c:occupant-compdev column.
croinfo –c disk –o cp displays the path which the specific disk occupies when it was installed on the system.

For other options, see the croinfo(1M) man page.

Note - The format command also provides physical device location information. See the sample output in Identifying Disks on a System.

Other commands display locations of devices as well. The following examples show how these commands are used to identify and locate devices.

Example 6-8 Using the diskinfo Command

This example assumes that you assigned the alias J4200@RACK10:U24-25 to the disk SUN-Storage-J4200.0905QAJ00E. For more information about disk aliases, see Obtaining Disk Information.

$ diskinfo
D:devchassis-path                                      c:occupant-compdev
-----------------------------------------------------  ------------------
/dev/chassis/J4200@RACK10:U24-25/SCSI_Device__0/disk   c2t0d0
/dev/chassis/J4200@RACK10:U24-25/SCSI_Device__1/disk   c2t1d0
/dev/chassis/J4200@RACK10:U24-25/SCSI_Device__2/disk   c2t2d0

Example 6-9 Using the prtconf Command

$ prtconf -l | more
