diskinfo(1M)diskinfo(1M)NAMEdiskinfo - describe characteristics of a disk device
The command determines whether the character special file named by
character_devicefile is associated with a SCSI or floppy disk drive.
If so, summarizes the disk's characteristics.
The command displays information about the following characteristics of
Vendor name Manufacturer of the drive (SCSI only)
Product ID Product identification number or ASCII name
Type Floppy or SCSI classification for the device
Disk Size of disk specified in bytes
Sector Specified as bytes per sector
Both the size of disk and bytes per sector represent formatted media.
The command recognizes the following options:
Return the size of the disk in 1024-byte sectors.
Display a verbose summary of all of the information
available from the device. For floppy drives, this
option has no effect.
SCSI disk devices return the following:
Vendor and product ID
Size (in bytes and in logical blocks)
Bytes per sector
SCSI conformance level data
Most of the diagnostic messages from are self-explanatory. However,
one diagnostic message deserves further clarification. If the command
fails to access the lunpath corresponding to a given special file, it
displays the following diagnostics data, which contains device identi‐
fication and capability information:
device type 127 (unknown); device is inaccessible

As of release 10.20 of HP-UX, certain IDE devices, CD-ROMs in particu‐
lar, will respond to inquiries as if they were SCSI devices. There‐
fore, the text "SCSI describe" in the output of the command does not
definitively mean that the disk is in fact a SCSI drive (especially in
the case of CD-ROMs). Use to check which type of INTERFACE node, SCSI
or IDE, the device's hardware path lies beneath, in order to defini‐
tively determine a drive's interface.
The command supports floppy and HP SCSI disk devices.
The SCSI specification provides for a wide variety of device-dependent
formats. For non-HP devices, may be unable to interpret all of the
data returned by the device. Refer to the drive operating manual
accompanying the unit for more information.
