SG_RMSN(8)                                    SG3_UTILS                                   SG_RMSN(8)

NAME
       sg_rmsn - send SCSI READ MEDIA SERIAL NUMBER command

SYNOPSIS
       sg_rmsn [--help] [--raw] [--readonly] [--verbose] [--version] DEVICE

DESCRIPTION
       Send a SCSI READ MEDIA SERIAL NUMBER command to DEVICE and outputs the response.

       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.

OPTIONS
       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 access.

       -v, --verbose
              increase the level of verbosity, (i.e. debug output).

       -V, --version
              print the version string and then exit.

NOTES
       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.

EXIT STATUS
       The  exit  status  of  sg_rmsn is 0 when it is successful. Otherwise see the sg3_utils(8) man
       page.
