SG_RMSN

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 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.
