NAME
----
nvme-cmdset-ind-id-ns - Send NVMe I/O Command Set Independent Identify Namespace, return result and structure.

SYNOPSIS
--------
[verse]
'nvme cmdset-ind-id-ns' <device> [--namespace-id=<nsid> | -n <nsid>]
			[--raw-binary | -b] [--human-readable | -H]
			[--output-format=<fmt> | -o <fmt>] [--verbose | -v]

DESCRIPTION
-----------
For the NVMe device given, sends an I/O Command Set Independent 
identify namespace 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).
If the character device is given, the `'--namespace-id'` option is
mandatory, otherwise it will use the ns-id of the namespace for the block
device you opened. For block devices, the ns-id used can be overridden
with the same option.

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
-------
-n <nsid>::
--namespace-id=<nsid>::
	Retrieve the identify namespace structure for the given nsid. This
	is required for the character devices, or overrides the block nsid
	if given.

-b::
--raw-binary::
	Print the raw buffer to stdout. Structure is not parsed by
	program. This overrides the vendor specific and human readable 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
--------
* Has the program interpret the returned buffer and display the known
fields in a human readable format:
+
------------
# nvme cmdset-ind-id-ns /dev/nvme0n1
------------
+

* If using the character device or overriding namespace id:
+
------------
# nvme cmdset-ind-id-ns /dev/nvme0 -n 1
# nvme cmdset-ind-id-ns /dev/nvme0n1 -n 1
# nvme cmdset-ind-id-ns /dev/nvme0 --namespace-id=1
------------
+

* Have the program return the raw structure in binary:
+
------------
# nvme cmdset-ind-id-ns /dev/nvme0n1 --raw-binary > id_ns.raw
# nvme cmdset-ind-id-ns /dev/nvme0n1 -b > id_ns.raw
------------
+
It is probably a bad idea to not redirect stdout when using this mode.
