# [DESCRIPTION](#DESCRIPTION)

For the NVMe device given, sends the nvme namespace detach command for the provided namespace identifier, detaching to the provided list of controller identifiers.

# [OPTIONS](#OPTIONS)

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

The namespace identifier to detach.

-c &lt;ctrl-list,&gt;, --controllers=&lt;ctrl-list,&gt;

The comma separated list of controller identifiers to detach the namespace from.

# [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.
