sg_rmsn − sends a SCSI READ MEDIA SERIAL NUMBER command
sg_rmsn [−−help] [−−raw] [−−verbose] [−−version] DEVICE
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.
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.
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 CDs and DVDs has a "media serial number" feature (0x109) [and a "logical unit serial number" feature]. These can be viewed with sg_get_config.
The exit status of sg_rmsn is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
