NAME

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

SYNOPSIS

10       nvme wdc id-ctrl <device> [-v | --vendor-specific] [-b | --raw-binary]
11                               [-H | --human-readable]
12                               [-o <fmt> | --output-format=<fmt>]
13

DESCRIPTION

15       For the NVMe device given, sends an identify controller command and
16       provides the result and returned structure.
17
18       The <device> parameter is mandatory and may be either the NVMe
19       character device (ex: /dev/nvme0), or a namespace block device (ex:
20       /dev/nvme0n1).
21
22       This will only work on WDC devices supporting this feature. Results for
23       any other device are undefined.
24
25       On success, the structure may be returned in one of several ways
26       depending on the option flags; the structure may be parsed by the
27       program or the raw buffer may be printed to stdout.
28
29       If having the program decode the output for readability, this version
30       will decode WDC vendor unique portions of the structure.
31

OPTIONS

33       -b, --raw-binary
34           Print the raw buffer to stdout. Structure is not parsed by program.
35           This overrides the vendor specific and human readable options.
36
37       -v, --vendor-specific
38           In addition to parsing known fields, this option will dump the
39           vendor specific region of the structure in hex with ascii
40           interpretation.
41
42       -H, --human-readable
43           This option will parse and format many of the bit fields into
44           human-readable formats.
45
46       -o <format>, --output-format=<format>
47           Set the reporting format to normal, json, or binary. Only one
48           output format can be used at a time.
49

EXAMPLES

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