NAME
       sg_rmsn - sends a SCSI READ MEDIA SERIAL NUMBER command

SYNOPSIS
       sg_rmsn [--help] [--raw] [--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 origi‐
       nally 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.

       -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 num‐
       ber" 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.
