NVME-LOG-HOST-DIS(1)

📦 version 3.2, in arch rolling

💖 NVME-LOG-HOST-DIS(1) 💖

okay bestie, so this is the nvme-log-host-discovery page from the NVMe Manual — yes, the whole thing, and no we are not skipping the "boring" bits, because every single flag here is lowkey important ✨

🌸 NAME 🌸

nvme-log-host-discovery — grab the Host Discovery Log and, like, show it to you 💅

🦋 SYNOPSIS 🦋

nvme [<global-options>] log host-discovery <device>
                        [--all-host-entries | -a]
                        [--rae | -r]

✨ DESCRIPTION ✨

Retrieve Host Discovery Log, show it. That's the whole vibe 🎀

The <device> parameter is mandatory — it's an NVMe MI device supported by the discovery controller, like for example mctp:<net>,<eid>[:ctrl-id]. No device, no log, no slay 🙈

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

💜 OPTIONS 💜

  • -a, --all-host-entries — All Host Entries. every last one of them 👑
  • -r, --rae — Retain an Asynchronous Event. yes, retain it. keep it. don't let it go 🫶

🌈 GLOBAL OPTIONS 🌈

these ones live at the top-level nvme command, bestie — but they're totally available to this subcommand too, iykyk 💫

  • --dry-run — Print the command that would be executed, but do not actually execute it. it's giving window shopping 🛍️
  • --no-ioctl-probing — Disable probing for 64-bit IOCTL support.
  • --no-retries — Disable retry logic on transient errors. one shot, no second chances 💀
  • -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. (yes, the json one has a stray quote in the original and we're keeping it fr fr, character for character 🎀)
  • --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. no custom versions, we don't do that here 🚫
  • --quiet — Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level. shhh 🤫
  • --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). no cap, it'll wait forever 😭
  • -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity. stack it, girl 📚

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

🍓 EXAMPLES 🍓

  • Has the program issue a host-discovery-log
