SYNOPSIS

nvme [<global-options>] endurance-log <device>
                        [--group-id=<group> | -g <group>]

DESCRIPTION

Retrieves the NVMe Endurance log page from an NVMe device and provides the returned structure.

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

On success, the returned endurance log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format, the raw buffer may be printed to stdout for another program to parse, or reported in json format.

OPTIONS

-g <group>
--group-id=<group>

The endurance group identifier.

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

  • Print the Endurance log page in a human readable format: 

    # nvme endurance-log /dev/nvme0

  • Print the raw Endurance log to a file: 

    # nvme endurance-log /dev/nvme0 --output=binary > endurance_log.raw

    It is probably a bad idea to not redirect stdout when using this mode.
