nvme-error-log(1)
=================
NAME
----
nvme-error-log - Send NVME Error log page request, return result and log
SYNOPSIS
--------
[verse]
'nvme error-log' <device> [--log-entries=<entries> | -e <entries>]
[--raw-binary | -b]
[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
DESCRIPTION
-----------
Retrieves NVMe Error 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 error 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
-------
-e <entries>::
--log-entries=<entries>::
Specifies how many log entries the program should request from
the device. This must be at least one, and shouldn't exceed the
device's capabilities. Defaults to 64 log entries.
-b::
--raw-binary::
Print the raw error 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
--------
* Get the error log and print it in a human readable format:
+
------------
# nvme error-log /dev/nvme0
------------
+
* Print the raw output to a file:
+
------------
# nvme error-log /dev/nvme0 --raw-binary > error_log.raw
------------
+
It is probably a bad idea to not redirect stdout when using this mode.
