NAME

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

SYNOPSIS

       nvme wdc id-ctrl <device> [--vendor-specific | -v] [--raw-binary | -b]
                               [--human-readable | -H]
                               [--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 WDC 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 WDC
       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:

               # nvme wdc id-ctrl /dev/nvme0
