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 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.

output the usage message then exit.
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.
increase the level of verbosity, (i.e. debug output).
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.
