🎀 nvme-sed-initialize(1) 🎀

okay so this is the nvme-sed-initialize(1) page from the NVMe Manual, and it’s literally your cheat sheet for prepping a SED Opal device so locking can happen. bestie, it’s giving small command, big security vibes 💅✨

✨ NAME ✨

nvme-sed-initialize — Initialize a SED Opal Device for locking. periodt 💖

🌸 SYNOPSIS 🌸

nvme [<global-options>] sed initialize [ --read-only, -r ] <device>

💖 DESCRIPTION 💖

Initialize the NVMe device given to allow SED Opal locking. That’s the whole mission, bestie — you hand over the NVMe device, and it gets initialized so SED Opal locking is allowed. No cap. 🦋

🦋 OPTIONS 🦋

  • -r, --read-only — Set locking range to read-only. Lowkey important, highkey simple 💅

👑 GLOBAL OPTIONS 👑

The following options are defined at the top-level nvme command and are available to this subcommand:

  • --dry-run — Print the command that would be executed, but do not actually execute it. Rehearsal mode, but make it Unix 🎀
  • --no-ioctl-probing — Disable probing for 64-bit IOCTL support. 🧚
  • --no-retries — Disable retry logic on transient errors. 💀
  • -o <fmt>, --output-format=<fmt> — Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time. Pick one vibe, please ✨
  • --output-format-version=<version> — Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names. Other versions are rejected. 🫶
  • --quiet — Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level. Shhh, but not in a sketchy way 🙈
  • --set-options=<key=value>[,<key=value>...] — Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir. 🔥
  • --timeout=<ms> — Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). Patience is a virtue, apparently ⭐
  • -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity. Say more, bestie 💬

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file. Rules are rules, but flags win 💚

🌈 EXAMPLES 🌈

nvme sed initialize /dev/nvme5n1

That’s the example, and it ate 💅🍓
