NAME

       nvme-primary-ctrl-caps - Send identify Primary Controller Caps, return result and structure

SYNOPSIS

       nvme primary-ctrl-caps <device> [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

DESCRIPTION

       For the NVMe device given, sends an identify primary Controller caps 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.

OPTIONS

       -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.

       -v, --verbose
           Increase the information detail in the output.

EXAMPLES

       •   Get Primary Ctrl Caps of the device in default format

               # nvme primary-ctrl-caps /dev/nvme0

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

               # nvme primary-ctrl-caps /dev/nvme0 --human-readable
               # nvme primary-ctrl-caps /dev/nvme0 -H
