💅 NVME-WDC-VS-FW-A(1), aka nvme-wdc-vs-fw-activate-history

okay so bestie, welcome to the manual page for NVME-WDC-VS-FW-A — it's the nvme-wdc-vs-fw-activate-history situation and honestly it's giving "niche but iconic" 💖 it runs an NVMe WDC vs-fw-activate-history Vendor Unique Command and returns the result. no cap, that's the whole vibe.

✨ NAME ✨

nvme-wdc-vs-fw-activate-history — Execute NVMe WDC vs-fw-activate-history Vendor Unique Command, return result 🎀

---

🌸 SYNOPSIS 🌸

nvme [<global-options>] wdc vs-fw-activate-history <device>

---

🦋 DESCRIPTION 🦋

so for the NVMe device you hand it, it reads a Vendor Unique WDC log page that returns the firmware activation history. literally that's it, that's the job 🫶

the <device> parameter is mandatory — not optional, not "eh maybe later", mandatory — and it has to be the NVMe character device (ex: /dev/nvme0).

⚠️ heads up: this will only work on WDC devices that support this feature. Results for any other device are undefined. so like, don't come crying to me if you point it at random hardware, it's giving chaos 💀

on success it returns 0, error code otherwise. slay.

🔥 FIRMWARE ACTIVATE HISTORY LOG PAGE DATA OUTPUT EXPLANATION 🔥

okay this is the part where the log page spills the tea about every field, so let's go field by field, no skips, periodt:

• Entry Number — The number of fw activate entry. The most recent 20 entries will be displayed. 👑 (yes, only the freshest 20, it's curated)
• Power on Hour — The time since the power on in hours:minutes:seconds.
• Power Cycle Count — The power cycle count that the firmware activation occurred.
• Current Firmware — The firmware level currently running on the SSD before the activation took place.
• New Firmware — The new firmware level running on the SSD after the activation took place. ✨ glow-up documented
• Slot Number — The slot that the firmware is being activated from.
• Commit Action Type — The commit action type associated with the firmware activation event.
• Result — The result of the firmware activation event. The output shall be in the format: Pass or Failed + error code.

💜 GLOBAL OPTIONS 💜

these are defined at the top-level nvme command and are available to this subcommand (yes, even the baby subcommands get the good stuff):

• --dry-run — Print the command that would be executed, but do not actually execute it. (all the plot, none of the consequences 🙈)
• --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. pick one, bestie, you can't have all of them 💅
• --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. (v2 is the main character, v1 is the nostalgia trip 🌈)
• --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. 👑
