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

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).

       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 Intel vendor unique
       portions of the structure.

Examples

       •   Has the program interpret the returned buffer and display the known fields in a human readable
           format:

               # nvme intel id-ctrl /dev/nvme0

Name

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

Nvme

       Part of the nvme-user suite

NVMe                                               02/16/2025                               NVME-INTEL-ID-CTR(1)

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.

Synopsis

nvmeintelid-ctrl <device> [--vendor-specific | -v] [--raw-binary | -b]
