NVME-FEAT-TEMP-TH(1)

💅 nvme-feat-temp-thresh(1) — the NVMe Manual, bestie edition

okay so picture this: it's nvme-feat-temp-thresh(1), straight out of the NVMe Manual, and it's here to get and set the temperature threshold feature. that's the whole vibe. let's go ✨

---

🦋 SYNOPSIS

nvme [<global-options>] feat temp-thresh <device>
                        [--tmpth=<tmpth> | -t <tmpth>] [--thsel=<thsel>]
                        [--sel=<select> | -S <select>] [--save | -s]

🌸 DESCRIPTION

Get and set temperature threshold feature. that's it, that's the plot 💖

The <device> parameter is mandatory, no cap — you literally cannot skip it. it can be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1). either one is valid, pick your fighter 🫶

here's the tea on how it behaves:

• If you pass the setting options (--tmpth or --thsel), the command will update the temperature threshold configuration for the device. so it's a write moment 👑
• If you omit those options, it retrieves and displays the current configuration. read-only era, we love a chill one 🌈

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

---

✨ OPTIONS ✨

• -t <tmpth>, --tmpth=<tmpth> — Temperature Threshold. gives the threshold temperature value in Kelvin (yes, Kelvin, we're being scientific today 🧚).
• --thsel=<thsel> — Threshold Type Select. says which type of threshold you mean (e.g., over-temperature threshold or under-temperature threshold). very "pick a lane" of it 💅
• -S <select>, --sel=<select> — Select (SEL): this 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
• -s, --save — Save the attribute so that it persists through all power states and resets. it really said "i'm staying" 💀🫶

---

👑 GLOBAL OPTIONS

these are defined at the top-level nvme command and are available to this subcommand too. shared custody, iconic:

• --dry-run — Print the command that would be executed, but do not actually execute it. window shopping only 🛍️
• --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 — don't be greedy 🙈
• --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. ngl, v2 is the main character 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 clock-watching allowed ⏳
• -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity. stack it, queen 📚

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, every single time 💅

🎀 EXAMPLES

• Has the program issue a feat temp-thresh to get the current configuration — the "just looking" example:

# nvme feat temp-thresh /dev/nvme0

• Has the program issue a feat temp-thresh to set the over-temperature threshold to 310 Kelvin — the "we're committing" example:

# nvme feat temp-thresh /dev/nvme0 --tmpth=310 --thsel=0 --save
