Finding Out the Disk Model Number and Other Information
Finding Out the Disk Model Number and
Other Information
The diskinfo command displays useful information about a disk.
Execute it specifying the disk's character device special file. For example,
/usr/sbin/diskinfo /dev/rdsk/c1t2d0
SCSI describe of /dev/rdsk/c1t2d0:
vendor: HP
product id: C3010M1
type: direct access
size: 1956086 Kbytes
bytes per sector: 512
SCSI disks can be further identified by the product ID field. The number
displayed does not correspond to the HP model number of the disk, but
rather to an "inquiry response" derived from querying the disk firmware
itself using a SCSI inquiry command. The inquiry response often
resembles a product number or product number family. (For example,
disks C243 x and C2440 all report C2430D.)
If you have a disk hardware problem and are working with an HP service
engineer, reporting the inquiry response gives him or her with useful
information such as firmware revision, disk mechanism, form factor, and
capacity.
