nvme-endurance-log − Send NVMe Endurance log page request, returns result and log
nvme
endurance−log <device>
[−−group−id=<group> | −g
<group>]
[−−output−format=<fmt> | −o
<fmt>]
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.
−g <group>, −−group−id=<group>
The endurance group identifier.
−o <format>, −−output−format=<format>
Set the reporting format to normal, json, or binary. Only one output format can be used at a time.
• 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.
