🌸 NAME 🌸

nvme-feat-err-recovery — Get and set error recovery feature.

✨ SYNOPSIS ✨

nvme [<global-options>] feat err-recovery <device>
                        [--nsid=<nsid> | -n <nsid>]
                        [--tler=<tler> | -t <tler>]
                        [--dulbe | -d]
                        [--sel=<select> | -S <select>] [--save | -s]

💖 DESCRIPTION 💖

Get and set the error recovery feature. That's the whole vibe. 💅

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

If any of the setting options (--tler or --dulbe) are specified, the command will update the error recovery configuration for the specified namespace. If neither option is specified, it will retrieve and display the current configuration. So it's like: set it or get it, choose your main character moment. ✨

On success it returns 0, error code otherwise. periodt.

🎀 OPTIONS 🎀

• -n <nsid>, --nsid=<nsid> — Sends the command with the requested nsid. This is required for character devices, or overrides the block nsid if given. The broadcast value 0xffffffff can also be given as all or -1.
• -t <tler>, --tler=<tler> — Time limited error recovery value. Indicates the limited retry time in 100 millisecond units.
• -d, --dulbe — Deallocated or unwritten logical block error enable.
• -S <select>, --sel=<select> — Select (SEL): This field specifies which value of the attributes to return in the provided data:
  • 0 — Name: current; Description: Current
  • 1 — Name: default; Description: Default
  • 2 — Name: saved; Description: Saved
  • 3 — Name: supported; Description: Supported capabilities
• -s, --save — Save the attribute so that it persists through all power states and resets.

🦋 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.
• --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. no cap. 👑

🌈 EXAMPLES 🌈

• Has the program issue a feat err-recovery to get the current configuration:

# nvme feat err-recovery /dev/nvme0n1

• Has the program issue a feat err-recovery to set tler and dulbe parameters:

# nvme feat err-recovery /dev/nvme0n1 --tler=10 --dulbe
