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	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.

       -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  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.
