nvme-id-ns(1)
=============
NAME
----
nvme-list-ns - Send NVMe Identify List Namespaces, return result and structure
SYNOPSIS
--------
[verse]
'nvme list-ns' <device> [--namespace-id=<nsid> | -n <nsid>]
[--csi=<command_set_identifier> | -y <command_set_identifier>]
[--all | -a]
[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
[--timeout=<timeout> | -t <timeout>]
DESCRIPTION
-----------
For the NVMe device given, sends an identify command for namespace list
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 starting namespace in the list always begins with 0 unless the
`'--namespace-id'` option is given to override.
On success, the namespace array is printed for each index and nsid for
a valid nsid.
OPTIONS
-------
-n <nsid>::
--namespace-id=<nsid>::
Retrieve the identify list structure starting with the given nsid.
-y <command_set_identifier>::
--csi=<command_set_identifier>::
If this value is given, retrieve the identify list structure associated
with the specified I/O command set.
-a::
--all::
Retrieve the identify list structure for all namespaces in the
subsystem, whether attached or inactive.
-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.
-t <timeout>::
--timeout=<timeout>::
Override default timeout value. In milliseconds.
EXAMPLES
--------
* Print the namespaces present for zoned command set in JSON format
+
------------
# nvme list-ns /dev/nvme0 -y 2 -a -o json
------------
* Print the namespaces present for NVM Command Set in normal format
+
------------
# nvme list-ns /dev/nvme0
