This section describes how to translate from a known UNIX logical device name such as c0t11d0s0 to a disk slot number (0 through 5).
This example assumes a known UNIX logical device name of c0t11d0s0.
Determine the UNIX physical device name from the UNIX logical device name.
Use the ls -l command to display the link for the logical device name in the /dev/dsk directory:
% ls -l /dev/dsk/c0t11d0s0 lrwxrwxrwx 1 root root 41 Nov 24 10:41 /dev/dsk/c0t11d0s0 -> ../../devices/pci@1f,4000/scsi@3/sd@b,0:a
The resulting output shows the UNIX physical device name associated with the logical device name. In this case, the corresponding physical device name is /pci@1f,4000/scsi@3/sd@b.
Determine the disk slot number using the prtconf command.
Substitute the string disk@ for sd@ in the physical device name determined in Step 1. The result in this example is /pci@1f,4000/scsi@3/disk@b.
Use the grep command to find this name in the output of the prtconf command:
% prtconf -vp | grep /pci@1f,4000/scsi@3/disk@b disk4: '/pci@1f,4000/scsi@3/disk@b,0' disk-slot4: '/pci@1f,4000/scsi@3/disk@b'
The resulting output indicates the corresponding disk slot number. In this example, the disk slot number is 4.
If the output does not provide a slot number, the device is either a removable media device (CD-ROM or tape drive) or an external device.
