SYNOPSIS

nvme [<global-options>] micron vs-smart-add-log <device> -f <json|normal>

DESCRIPTION

This command prints NAND information (Total bytes written, Bad block count and Erase failures etc) for the given micron device if its of 2200 model controller. For OCP complaint controllers this command print extended SMART health data along with NAND information (if available)

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

The -f option controls the displayed output data format based on the option value. If the option value is json (which is enabled by default), output data is printed in JSON format. If option value is normal the output is displayed in non-JSON format.

This will only work on Micron devices devices of model numbers 54XX and OCP complaint controllers. Support for new devices may be added subsequently.

OPTIONS

-f <json|normal>

Controls the format of displayed output.

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.

--timeout=<ms>

Set the timeout for the command in milliseconds.

-v
--verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

EXAMPLES

  • Retrieve NAND/extended SMART data and display in json format 

    # nvme micron vs-nand-stats /dev/nvme0

* Retrieve NAND/extended SMART data and display in non-json format
+

# nvme micron vs-nand-stats /dev/nvme0 -f normal
