NAME
----
nvme-fw-log - Send NVMe Firmware log page request, returns result and log

SYNOPSIS
--------
[verse]
'nvme fw-log' <device> [--raw-binary | -b]
			[--output-format=<fmt> | -o <fmt>] [--verbose | -v]

DESCRIPTION
-----------
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.

OPTIONS
-------
-b::
--raw-binary::
	Print the raw fw log buffer to stdout.

-o <fmt>::
--output-format=<fmt>::
	Set the reporting format to 'normal', 'json' or 'binary'. Only one
	output format can be used at a time.

-v::
--verbose::
	Increase the information detail in the output.

EXAMPLES
--------
* 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.
