NVME-WDC-VS-NAND-STATS(1)

okay bestie, welcome to the NVME-WDC-VS-NAND manual page — aka all about nvme-wdc-vs-nand-stats — and it's literally here to send a WDC vendor unique command and hand you back NAND stats 🦋✨

💖 NAME 💖

nvme-wdc-vs-nand-stats — send the NVMe WDC vs-nand-stats Vendor Unique Command, return result. That's the whole name, bestie 💅

🎀 SYNOPSIS 🎀

nvme [<global-options>] wdc vs-nand-stats <device>

🌸 DESCRIPTION 🌸

For the NVMe device you give it, this sends a Vendor Unique WDC vs-nand-stats command and outputs the NAND statistics. The --output-format option will format the output exactly as specified, no cap 💅

The <device> parameter is mandatory — like, required required — and may be either the NVMe character device (ex: /dev/nvme0).

This will only work on WDC devices supporting this feature. Results for any other device are undefined — and bestie, undefined is giving “do not test your luck” energy 💀

On success it returns the NAND statistics, error code otherwise. That's the deal 😭

💅 OPTIONS 💅

🌍 GLOBAL OPTIONS 🌍

These are defined at the top-level nvme command and are available to this subcommand, bestie:

• --dry-run — print the command that would be executed, but do not actually execute it. It's giving “look but don't touch” ✨
• --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 — every single time 💅

cute sign-off from the footer: it only gives the manual name NVME-WDC-VS-NAND() — no extra source/version or date info to spill — so that's the whole footer vibe, byeee 🫶🎀
