SG_RMSN(8) SG3_UTILS SG_RMSN(8) 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 re- sponse. 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 con- tain 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 ac- tion is to print the serial number out in ASCII-HEX with ASCII char- acters to the right. All error messages are sent to stderr. -R, --readonly opens the DEVICE read-only rather than read-write which is the de- fault. 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 re- sponse and its VPD pages (see sg_vpd). The relevant VPD pages are the "de- vice 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 num- ber" 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. AUTHORS Written by Douglas Gilbert.
