NAME

       sg_rmsn - sends a 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 manda-
       tory 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.
