nvme-effects-log(1)
===================

NAME
----
nvme-effects-log - Send NVMe Command Effects log page request, returns result
and log

SYNOPSIS
--------
[verse]
'nvme effects-log' <device> [--human-readable | -H] [--raw-binary | -b]
			[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
			[--timeout=<timeout> | -t <timeout>]

DESCRIPTION
-----------
Retrieves the NVMe Command Effects log page from an NVMe device and provides
the returned structure.

The <device> parameter is mandatory and should be the NVMe character
device (ex: /dev/nvme0).

On success, the returned command effects log structure will be printed
for each command that is supported.

OPTIONS
-------

-H::
--human-readable::
	This option will parse and format many of the bit fields into a
	human-readable format.

-b::
--raw-binary::
	This option will print the raw buffer to stdout. Structure is not
	parsed by program. This overrides the human-readable option.

-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.

-t <timeout>::
--timeout=<timeout>::
	Override default timeout value. In milliseconds.

EXAMPLES
--------
* Print the effects log page in a human readable format:
+
------------
# nvme effects-log /dev/nvme0
------------
+

* Have the program return the raw structure in binary:
+
------------
# nvme effects-log /dev/nvme0 --raw-binary > effects_log.raw
# nvme effects-log /dev/nvme0 -b > effects_log.raw
------------
