💖 SG_RMSN(8) — SG3_UTILS bestie edition 💖

okay so this is the SG3_UTILS manual page for sg_rmsn(8), and we're gonna make it make sense together 🫶

NAME 🌸

sg_rmsn — send the SCSI READ MEDIA SERIAL NUMBER command, bestie 💅

SYNOPSIS ✨

sg_rmsn [--help] [--raw] [--readonly] [--verbose] [--version] DEVICE

DESCRIPTION 🦋

So like, sg_rmsn sends a SCSI READ MEDIA SERIAL NUMBER command to DEVICE and outputs the response. That's the whole main character energy of this page 💖

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 a mandatory command, and ngl the author has not seen any SCSI devices that support it 😭💀

OPTIONS 💅

Arguments to long options are mandatory for short options as well. periodt.

  • -h, --help — output the usage message then exit. cute and helpful 🎀
  • -r, --raw — sends the serial number (if found) to stdout. Heads up bestie: 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. slay that raw output 🌈
  • -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. lowkey important 🫶
  • -v, --verbose — increase the level of verbosity, (i.e. debug output). it's giving “tell me everything” energy 🔥
  • -V, --version — print the version string and then exit. iconic lil version check 👑

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). iykyk 💜

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. obsessed with all these serial number side quests fr fr 🍓

EXIT STATUS 🎀

The exit status of sg_rmsn is 0 when it is successful. Otherwise see the sg3_utils(8) man page. vibe check passed = 0 💖
