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
