NAME

6       nvme-huawei-id-ctrl - Send NVMe Identify Controller, return result and
7       structure
8

SYNOPSIS

10       nvme huawei id-ctrl <device> [-v | --vendor-specific] [-b | --raw-binary]
11                               [-o <fmt> | --output-format=<fmt>]
12

DESCRIPTION

14       For the NVMe device given, sends an identify controller command and
15       provides the result and 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       This will only work on Huawei devices supporting this feature. Results
22       for any other device are undefined.
23
24       On success, the structure may be returned in one of several ways
25       depending on the option flags; the structure may be parsed by the
26       program or the raw buffer may be printed to stdout.
27
28       If having the program decode the output for readability, this version
29       will decode Huawei vendor unique portions of the structure.
30

OPTIONS

32       -b, --raw-binary
33           Print the raw buffer to stdout. Structure is not parsed by program.
34           This overrides the vendor specific and human readable options.
35
36       -v, --vendor-specific
37           In addition to parsing known fields, this option will dump the
38           vendor specific region of the structure in hex with ascii
39           interpretation.
40
41       -H, --human-readable
42           This option will parse and format many of the bit fields into
43           human-readable formats.
44
45       -o <format>, --output-format=<format>
46           Set the reporting format to normal, json, or binary. Only one
47           output format can be used at a time.
48

EXAMPLES

50       •   Has the program interpret the returned buffer and display the known
51           fields in a human readable format:
52
53               # nvme huawei id-ctrl /dev/nvme0
