sg_rmsn - send SCSI READ MEDIA SERIAL NUMBER command
] [ --version
Send a SCSI READ MEDIA SERIAL NUMBER command to DEVICE
and outputs the
This command is described in SPC-3 found at www.t10.org . It was originally
added to SPC-3 in revision 11 (2003/2/12). It is not an mandatory command and
the author has not seen any SCSI devices that support it.
Arguments to long options are mandatory for short options as well.
- -h, --help
- output the usage message then exit.
- -r, --raw
- sends the serial number (if found) to stdout. This output
may contain non-printable characters (e.g. the serial number is padded
with NULLs at the end so its length is a multiple of 4). The default
action is to print the serial number out in ASCII-HEX with ASCII
characters to the right. All error messages are sent to stderr.
- -R, --readonly
- opens the DEVICE read-only rather than read-write which is
the default. The Linux sg driver needs read-write access for the SCSI READ
MEDIA SERIAL NUMBER command but other access methods may require read-only
- -v, --verbose
- increase the level of verbosity, (i.e. debug output).
- -V, --version
- print the version string and then exit.
Device identification information is also found in a standard INQUIRY response
and its VPD pages (see sg_vpd). The relevant VPD pages are the "device
identification page" (VPD page 0x83) and the "unit serial
number" page (VPD page 0x80).
The MMC-4 command set for CD/DVD/HD-DVD/BD drives has a "media serial
number" feature (0x109) [and a "logical unit serial number"
feature]. These can be viewed with sg_get_config.
The exit status of sg_rmsn is 0 when it is successful. Otherwise see the
sg3_utils(8) man page.
