# [SYNOPSIS](#SYNOPSIS)

nvme [<global-options>] zns close-zone <device>


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


                                                [--start-lba=<LBA> | -s <LBA>]

# [DESCRIPTION](#DESCRIPTION)

For the NVMe device given, issues the Zone Management Send command with the "Close Zone" action. This will transition the zone to the closed state.

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).

# [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 close.

-a, --select-all

Select all zones for this action

# [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)

•Close all zones on namespace 1:

```
# nvme zns close-zone /dev/nvme0 -a -n 1
```
