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 C243x 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.
