🎀 NAME 🎀

okay bestie, welcome to NVME-FEAT-LBA-RAN(1) — the NVMe Manual page for nvme-feat-lba-range-type — and it is literally here for one iconic job: Get and set lba range type feature. slay. 💅

✨ SYNOPSIS ✨

nvme [<global-options>] feat lba-range-type <device>
                        [--nsid=<nsid> | -n <nsid>] [--num=<num> | -N <num>]
                        [--types=<type-list,> | -t <type-list,>]
                        [--lbaros=<lbaro-list,> | -l <lbaro-list,>]
                        [--hlbars=<hlbar-list,>]
                        [--slbas=<slba-list,> | -s <slba-list,>]
                        [--nlbs=<nlb-list,> | -b <nlb-list,>]
                        [--guids=<guid-list,> | -g <guid-list,>]
                        [--sel=<select> | -S <select>] [--save]

🦋 DESCRIPTION 🦋

okay so this command is your get-and-set situation for the LBA range type feature. Get and set lba range type feature — that's the whole vibe, no cap.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1). choose your fighter.

If the character device is given, the --nsid option is mandatory, otherwise it will use the ns-id of the namespace for the block device you opened. For block devices, the ns-id used can be overridden with the same option.

🚨 bestie, note the mandatory bit: character device without --nsid is a no.

On success it returns 0, error code otherwise.

---

🎀 OPTIONS 🎀

• -n <nsid>, --nsid=<nsid> — Sends the command with the requested nsid. This is required for the character devices, or overrides the block nsid if given. The broadcast value 0xffffffff can also be given as all or -1.
• -N <num>, --num=<num> — zeroes based LBA ranges number.
• -t <type-list,>, --types=<type-list,> — LBA range type list.
• -l <type-list,>, --lbaros=<lbaro-list,> — LBA range overwriteable list.
• --hlbars=<hlbar-list,> — hide LBA range list.
• -s <slba-list,>, --slbas=<slba-list,> — starting LBA list.
• -b <nlb-list,>, --nlbs=<nlb-list,> — zeroes based logical blocks number list.
• -g <guid-list,>, --guids=<guid-list,> — unique identifier list. Only supported with __int128 available.
• -S <select>, --sel=<select> — The Select (SEL) field specifies which value of the attributes to return in the provided data:
  • 0 — current — Current
  • 1 — default — Default
  • 2 — saved — Saved
  • 3 — supported — Supported capabilities
• --save — Save the attribute so that it persists through all power states and resets.

---

🌈 GLOBAL OPTIONS 🌈

These 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.
• --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.
• --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.
• --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).
• -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.

🌸 EXAMPLES 🌸

• This one has the program issue a feat lba-range-type to get:

# nvme feat lba-range-type /dev/nvme0 -n 1

• This one has the program issue a ocp feat lba-range-type with LBA ranges to set:

# nvme feat lba-range-type /dev/nvme0n1 --num=1 -t 0,1 -l 0,1 -h 1,0 -b 7,7 -s 0,4096 -g 1234,5678
