💖 NVME-SED-UNLOCK(1) 💖

okay so bestie, this is a page from the NVMe Manual and it's literally all about nvme-sed-unlock — the little icon that unlocks a SED Opal Device 🎀 ngl it's short but it ATE.

✨ NAME ✨

nvme-sed-unlock — unlock a SED Opal device 🦋

🌸 SYNOPSIS 🌸

nvme [<global-options>] sed unlock
                        [--read-only | -r]
                        [--ask-key | -k]
                        <device>

💅 DESCRIPTION 💅

Unlocks the NVMe device you hand it. That's the whole vibe. You point at <device>, it unlocks 💫

🔥 OPTIONS 🔥

• -r, --read-only — sets the locking range to read-only. like, it's unlocked but it's giving "look, don't touch" 💀
• -k, --ask-key — prompts you for the SED authentication key. yes queen, type it in 🫶

👑 GLOBAL OPTIONS 👑

bestie these are defined up at the top-level nvme command, but they're available to this subcommand too, so don't forget they exist:

• --dry-run — prints the command that would be executed, but does not actually execute it. all the fantasy, none of the consequences 🙈
• --no-ioctl-probing — disables probing for 64-bit IOCTL support.
• --no-retries — disables the retry logic on transient errors. one shot, no second chances 😭
• -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. only one output format at a time, so pick your fave ✨
• --output-format-version=<version> — selects 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 — no gatecrashing 💅
• --quiet — suppresses informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. she's quiet but she's still watching 👀
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). time is fake ⭐
• -v, --verbose — increases the level of detail in the output. may be specified multiple times to further increase verbosity. say it with me: more -v = more tea 🍓

heads up bestie: these options can also be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file. flags stay winning 👑
