========================
NAME
----
nvme-zns-report-zones - Retrieve and display the Report Zones data structure
SYNOPSIS
--------
[verse]
'nvme zns report-zones' <device> [--namespace-id=<NUM> | -n <NUM>]
[--start-lba=<IONUM> | -s <IONUM>]
[--descs=<NUM> | -d <NUM>]
[--state=<NUM> | -S <NUM>]
[--extended | -e]
[--partial | -p]
[--verbose | -v]
[--output-format=<fmt> | -o <fmt>]
DESCRIPTION
-----------
For the NVMe device given, sends the Zone Management Receive command with the
Zone Receive Action set to either Report Zones or Extended Report Zones,
depending on the 'extended' option.
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 data structure returned by the device will be decoded and
displayed in one of several ways.
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.
-s <lba>::
--start-lba=<lba>::
The starting LBA of the zone to begin the report
-d <NUM>::
--descs=<NUM>::
The number of descriptors to request in the report.
-S <NUM>::
--state=<NUM>::
The state of zones to request in the report. Known values include:
+
[]
|=================
|Value|Definition
|0|List all zones (default)
|1|Empty State
|2|Implicitly Opened State
|3|Explicitly Opened State
|4|Closed State
|5|Full State
|6|Read Only State
|7|Offline State
|=================
-e::
--extended::
Request to use the Extended Report Zones option. The extended data is
not decoded.
-p::
--partial::
If set, the device will return the number of zones that match the state
rather than the number of zones returned in the report.
-v::
--verbose::
Increase the information detail in the output.
-o <fmt>::
--output-format=<fmt>::
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 report for 16 zones, and display the known
fields in a human readable format:
+
------------
# nvme zns report-zones /dev/nvme0 -n 1 -d 16
------------
+
* Show the output in json format with extra details
+
------------
# nvme zns report-zones /dev/nvme0 -n 1 -d 16 -o json
