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.
