# [DESCRIPTION](#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 &lt;device&gt; 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](#OPTIONS)

-n &lt;NUM&gt;, --namespace-id=&lt;NUM&gt;

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 &lt;lba&gt;, --start-lba=&lt;lba&gt;

The starting LBA of the zone to begin the report

-d &lt;NUM&gt;, --descs=&lt;NUM&gt;

The number of descriptors to request in the report.

-S &lt;NUM&gt;, --state=&lt;NUM&gt;

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.

# [GLOBAL OPTIONS](#GLOBAL_OPTIONS)

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

Select the output format version. Version *1* uses the original field naming, while version *2* (default) provides more consistent and script-friendly field names.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds.

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.

# [EXAMPLES](#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
```
