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
Use the croinfo command options 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 that the specific disk occupies when it was installed on the system.
For more information about other options, see the croinfo(8) man page.
The following examples show how you can use other commands to identify and locate devices.
Example 44 Using the diskinfo CommandThis 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 c2t2d0Example 45 Using the prtconf Command
This example shows how to use the ptrconf command to display disk information.
