NAME
nvme-log-endurance - Send NVMe Endurance log page request, returns result and log
SYNOPSIS
nvme [<global-options>] log endurance <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. 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). A command-line flag always overrides the file.
EXAMPLES
• Print the Endurance log page in a human readable format:
# nvme log endurance /dev/nvme0
• Print the raw Endurance log to a file:
# nvme log endurance /dev/nvme0 --output=binary > endurance_log.raw
It is probably a bad idea to not redirect stdout when using this mode.
