# [NAME](#NAME)

nvme-zns-set-zone-desc - Set extended descriptor data for a zone

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] zns set-zone-desc <device>


                        [--namespace-id=<NUM> | -n <NUM>]


                        [--start-lba=<IONUM>, -s <IONUM>]


                        [--zrwaa | -r]


                        [--data=<FILE>, -d <FILE>]
```

# [DESCRIPTION](#DESCRIPTION)

For the NVMe device given, issues the Zone Management Send command with the Set Zone Descriptor Extensions action. The input will default to stdin. Alternatively, the data may come from a file that can be specified. The data length will automatically be calculated from the zns identify namespace.

# [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 manage send.

-r, --zrwaa

Allocate Zone Random Write Area to zone.

-d &lt;FILE&gt;, --data=&lt;FILE&gt;

Optional file for data (default stdin)

# [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)

•Write "hello world" into the zone descriptor for namespace 1’s first zone (requires device supports a large enough zone extended data)

```
# echo "hello world" | nvme zns set-zone-desc /dev/nvme0 -n 1 -s 0
```
