💅 nvme-wdc-vs-telemetry-controller-option — bestie edition

okay so this is a page from the NVMe Manual for the command nvme-wdc-vs-telemetry-controller-option, and honestly? it's giving niche-but-iconic. it only applies to one very specific thing on one very specific kind of drive, and we're gonna walk through it together 🫶

✨ NAME ✨

nvme-wdc-vs-telemetry-controller-option — turns the controller initiated option of the telemetry log page off, on, or just checks where it's at. that's the whole vibe 💅

---

🌸 SYNOPSIS 🌸

nvme [<global-options>] wdc vs-telemetry-controller-option <device>
                        [--disable, -d] [--enable, -e] [--status, -s]

---

🦋 DESCRIPTION 🦋

so for the NVMe device you hand over, this sends the WDC Vendor Specific set feature command — and what that command does is disable, enable, or get the current status of the controller initiated option of the telemetry log page. three moods, one command, we love a multitasker ✨

the <device> parameter is mandatory and it's a NVMe character device — think something like /dev/nvme0. no device, no party 🙈

⚠️ real talk: this only works on WDC devices that actually support this feature. results for any other device are undefined — as in, don't come crying to me if you point it at a random drive. undefined is undefined, periodt 💀

🎀 OPTIONS 🎀

• -d, --disable — disables the controller initiated option of the telemetry log page. bye bye feature 👋
• -e, --enable — enables the controller initiated option of the telemetry log page. hello again feature 💖
• -s, --status — returns the current status (enabled or disabled) of the controller initiated option of the telemetry log page. she's just here to check in 🔍

---

👑 GLOBAL OPTIONS 👑

these are the options that live up at the top-level nvme command, and yes bestie, they're available to this subcommand too. iykyk 🌈

• --dry-run — prints the command that would be executed, but does not actually execute it. window shopping only 🛍️
• --no-ioctl-probing — disables probing for 64-bit IOCTL support.
• --no-retries — disables the retry logic on transient errors. one shot, one opportunity 🎯
• -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, json, or binary. only one output format may be used at a time, so pick a lane ✋
• --output-format-version=<version> — selects the output format version. version 1 uses the original field naming, while version 2 (the default) provides more consistent and script-friendly field names. other versions are rejected — no third options here 🚫
• --quiet — suppresses informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. shhh 🤫
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). patience is a virtue 🧘
• -v, --verbose — increases the level of detail in the output. may be specified multiple times to further increase verbosity. the more the messier, and we stan 📈

also important: these options can be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file — command line stays main character energy 👑
