+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, sends an identify controller command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+This will only work on Huawei devices supporting this feature\&. Results for any other device are undefined\&.
+.sp
+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\&.
+.sp
+If having the program decode the output for readability, this version will decode Huawei vendor unique portions of the structure\&.
+.SH "OPTIONS"
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&. This overrides the vendor specific and human readable options\&.
+.RE
+.PP
+\-v, \-\-vendor\-specific
+.RS 4
+In addition to parsing known fields, this option will dump the vendor specific region of the structure in hex with ascii interpretation\&.
+.RE
+.PP
+\-H, \-\-human\-readable
+.RS 4
+This option will parse and format many of the bit fields into human\-readable formats\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.

+=====================

+NAME
+----
+nvme-huawei-id-ctrl - Send NVMe Identify Controller, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme huawei id-ctrl' <device> [-v | --vendor-specific] [-b | --raw-binary]
+ [-o <fmt> | --output-format=<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 <format>::
+--output-format=<format>::
+ 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:
