NVME-MICRON-ID-CT(1)

💖 NAME 💖

okay so bestie, welcome to the nvme-micron-id-ctrl(1) page — it's giving “send NVMe Identify Controller with Micron vendor-specific fields,” and yes that's literally the whole vibe. 💅

✨ SYNOPSIS ✨

nvme [<global-options>] micron id-ctrl <device>

🌸 DESCRIPTION 🌸

So for the NVMe device you give it, this sends an identify controller command and gives you the result with the Micron vendor-specific fields decoded. slay. ✨

The <device> parameter is mandatory — no cap, you gotta pass it — and it can be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

This command extends the standard Identify Controller output with these Micron-specific fields:

• PMS (Power Measurement Support) — Bit 21 of CTRATT (Controller Attributes). It indicates whether the controller supports power measurement.
• IPMSR (Interval Power Measurement Sample Rate) — Located at bytes 392-393 in the Identify Controller reserved area. It specifies the sample rate for interval power measurement.
• MSMT (Maximum Stop Measurement Time) — Located at bytes 394-395 in the Identify Controller reserved area. It specifies the maximum time to stop power measurement.

💅 OPTIONS 💅

🫶 GLOBAL OPTIONS 🫶

The following options are defined at the top-level nvme command and are available to this subcommand:

• --dry-run — Print the command that would be executed, but do not actually execute it. literally just peek, 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 — pick one, bestie, you can't have all four. 🎀
• --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 — nope, not those. 🙈
• --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 — yes, you can stack it. 💜

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

🦋 EXAMPLES 🦋

• Display Identify Controller in human-readable format:

# nvme micron id-ctrl /dev/nvme0

• Display Identify Controller in JSON format:

# nvme micron id-ctrl /dev/nvme0 -o json
