nvme-huawei-id-ctrl - Send NVMe Identify Controller, return result and structure
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'nvme huawei id-ctrl' <device> [--vendor-specific | -v] [--raw-binary | -b]
|
|
[--output-format=<fmt> | -o <fmt>]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
For the NVMe device given, sends an identify controller command and
|
|
provides the result and 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).
|
|
|
|
This will only work on Huawei devices supporting this feature.
|
|
Results for any other device are undefined.
|
|
|
|
On success, the structure may be returned in one of several ways depending
|
|
on the option flags; the structure may be parsed by the program or the
|
|
raw buffer may be printed to stdout.
|
|
|
|
If having the program decode the output for readability, this version
|
|
will decode Huawei vendor unique portions of the structure.
|
|
|
|
OPTIONS
|
|
-------
|
|
-b::
|
|
--raw-binary::
|
|
Print the raw buffer to stdout. Structure is not parsed by
|
|
program. This overrides the vendor specific and human readable options.
|
|
|
|
-v::
|
|
--vendor-specific::
|
|
In addition to parsing known fields, this option will dump
|
|
the vendor specific region of the structure in hex with ascii
|
|
interpretation.
|
|
|
|
-H::
|
|
--human-readable::
|
|
This option will parse and format many of the bit fields
|
|
into human-readable formats.
|
|
|
|
-o <fmt>::
|
|
--output-format=<fmt>::
|
|
Set the reporting format to 'normal', 'json', or
|
|
'binary'. Only one output format can be used at a time.
|
|
|
|
EXAMPLES
|
|
--------
|
|
* Has the program interpret the returned buffer and display the known
|
|
fields in a human readable format:
