NAME

6       nvme-fw-log - Send NVMe Firmware log page request, returns result and
7       log
8

SYNOPSIS

10       nvme fw-log <device> [--raw-binary | -b]
11                               [--output-format=<fmt> | -o <fmt>]
12

DESCRIPTION

14       Retrieves the NVMe Firmware log page from an NVMe device and provides
15       the returned structure.
16
17       The <device> parameter is mandatory and may be either the NVMe
18       character device (ex: /dev/nvme0), or a namespace block device (ex:
19       /dev/nvme0n1).
20
21       On success, the returned f/w log structure may be returned in one of
22       several ways depending on the option flags; the structure may parsed by
23       the program and printed in a readable format or the raw buffer may be
24       printed to stdout for another program to parse.
25

OPTIONS

27       -b, --raw-binary
28           Print the raw fw log buffer to stdout.
29
30       -o <format>, --output-format=<format>
31           Set the reporting format to normal, json, or binary. Only one
32           output format can be used at a time.
33

EXAMPLES

35       •   Print the firmware log page in a human readable format:
36
37               # nvme fw-log /dev/nvme0
38
39       •   Print the log firmware to a file:
40
41               # nvme fw-log /dev/nvme0 --raw-binary > fw_log.raw
42
43           It is probably a bad idea to not redirect stdout when using this
44           mode.
