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.
