# nvme-micron-id-ctrl(1)

Send NVMe Identify Controller with Micron vendor-specific fields

## NAME

nvme-micron-id-ctrl - Send NVMe Identify Controller with Micron vendor-specific fields

## SYNOPSIS

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

## DESCRIPTION

For the NVMe device given, sends an identify controller command and provides the result with Micron vendor-specific fields decoded.

The \<device\> parameter is mandatory and may 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 Micron-specific fields:

PMS (Power Measurement Support)

Bit 21 of CTRATT (Controller Attributes). Indicates whether the controller supports power measurement.

IPMSR (Interval Power Measurement Sample Rate)

Located at bytes 392-393 in the Identify Controller reserved area. Specifies the sample rate for interval power measurement.

MSMT (Maximum Stop Measurement Time)

Located at bytes 394-395 in the Identify Controller reserved area. 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.

- \--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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## 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
```
