nvme-nvm-id-ns(1)
=================
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>]
[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
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
-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 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.
