To facilitate disk identification, assign aliases to the disks. Use the following command:
# fmadm add-alias chassis-name.chassis-serial alias-id
You can set a naming standard so that the alias name maps to a specific disk's chassis name and chassis serial number. The following example maps the disk with chassis name SUN-Storage-J4200 and serial number 0905QAJ00E to an alias.
# fmadm add-alias SUN-Storage-J4200.0905QAJ00E J4200@RACK10:U24-25
For more information about assigning aliases to disks, see the fmadm(1M) man page.
