NAME
----
nvme-nvm-id-ns - Send NVMe Identify NVM Command Set specific Namespace data structure, display structure

SYNOPSIS
--------
[verse]
'nvme nvm-id-ns' <device> [--uuid-index=<uuid-index> | -U <uuid_index>]
			[--namespace-id=<NUM> | -n <NUM>]
			[-v | --verbose]
			[--output-format=<fmt> | -o <fmt>]

DESCRIPTION
-----------
Identify NVM Command Set specific Namespace data structure for the specified
NSID for the NVM Command Set specified in the CSI field.

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
-------
-n <NUM>::
--namespace-id=<NUM>::
	Use the provided namespace id for the command. If not provided, the
	namespace id of the block device will be used. If the command is issued
	to a non-block device, the parameter is required.

-U <uuid-index>::
--uuid-index=<uuid-index>::
	UUID Index of the feature

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

-o <format>::
--output-format=<format>::
              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 nvm-id-ns /dev/nvme0n1
------------
+

* If using the character device or overriding namespace id:
+
------------
# nvme nvm-id-ns /dev/nvme0 -n 1
# nvme nvm-id-ns /dev/nvme0n1 -n 1
# nvme nvm-id-ns /dev/nvme0 --namespace-id=1
------------
+
* Have the program return the raw structure in binary:
+
------------
# nvme nvm-id-ns /dev/nvme0n1 -o binary > id_ns.raw
# nvme nvm-id-ns /dev/nvme0n1 --output-format=binary > id_ns.raw
------------
+
It is probably a bad idea to not redirect stdout when using this mode.

* Alternatively you may want to send the data to another program that
can parse the raw buffer.
