nvme-fw-log − Send NVMe Firmware log page request, returns result and log
nvme
fw−log <device>
[−−raw−binary | −b]
[−−output−format=<fmt> | −o
<fmt>]
Retrieves the NVMe Firmware 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 f/w 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 or the raw buffer may be printed to stdout for another program to parse.
−b, −−raw−binary
Print the raw fw log buffer to stdout.
−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 firmware log page in a human readable format:
# nvme fw−log /dev/nvme0
• Print the log firmware to a file:
# nvme fw−log /dev/nvme0 −−raw−binary > fw_log.raw
It is probably a bad idea to not redirect stdout when using this mode.
