💅 nvme-fdp-update — Reclaim Unit Handle Update 🎀

Okay so bestie, welcome to nvme-fdp-update, a page straight out of the NVMe Manual, and honestly? It's a little niche but it slaps. The way this one works is you point your placement identifiers at a whole different Reclaim Unit that the namespace you picked can actually reach. Main character energy for your storage, fr fr. ✨

---

🌸 SYNOPSIS 🌸

nvme [<global-options>] fdp update <device>
                        [--namespace-id=<NUM> | -n <NUM>]
                        [--pids=<NUM,> | -p <NUM,>]

Like, <device> is the star of the show, and the rest are the little accessories that make the fit complete. 💅

🦋 DESCRIPTION 🦋

So for the NVMe device you hand over, this updates the Placement Identifiers you give it so they reference a different Reclaim Unit — one that the namespace you specify can actually access. Basically you're re-pointing your identifiers at new digs. No cap. 🔥

---

✨ OPTIONS ✨

• -n <NUM>, --namespace-id=<NUM> — the namespace identifier, iykyk. Also, the broadcast value 0xffffffff can be handed over as either all or -1, so you've got options (literally).
• -p <NUM,>, --pids=<NUM,> — a comma-separated list of the placement identifiers you want to update. One, or a whole lil squad of them. 🫶

🌈 GLOBAL OPTIONS 🌈

These ones live up at the top-level nvme command, but they're totally available to this subcommand too — like the cool older siblings who let you sit with them. 👑

• --dry-run — prints the command that would be executed but doesn't actually run it. Bestie, it's a dress rehearsal, not the real performance. 🎀
• --no-ioctl-probing — disables probing for 64-bit IOCTL support.
• --no-retries — turns off 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, bestie — pick a lane. ✨
• --output-format-version=<version> — selects the output format version. Version 1 uses the original field naming, while version 2 (that's the default) gives you more consistent and script-friendly field names. Any other versions get rejected, periodt. 🙈
• --quiet — suppresses informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level. It's giving "shush but not that shush." 🤫
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. The supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir. Mix and match, key=value style. 💜
• --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits with no time limit at all (0xffffffff). Patience is a vibe. 🧚
• -v, --verbose — increases the level of detail in the output. You can specify it multiple times to crank the verbosity even further. Go off, honestly. 🔥

Also important: these options can be set as machine-wide defaults in nvme-cli.conf(5). And a command-line flag always overrides the file — CLI stays winning, no cap. 👑

And that's the whole page, bestie! Huge shoutout to the NVMe Manual — this one's from the NVMe source, version-dated 10/30/2026, and it's the NVME-FDP-UPDATE(1) page. Go forth and update those Reclaim Unit Handles. Slay. 💖🦋🌸
