NVME-DISCONNECT-AL(1) NVMe Manual NVME-DISCONNECT-AL(1)

# [NAME](#NAME)

nvme-disconnect-all - Disconnect from all connected Fabrics controllers.

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] disconnect-all


                        [--transport=<STR> | -t <STR>]


                        [--owner=<NAME>]


                        [--force]
```

# [DESCRIPTION](#DESCRIPTION)

Disconnects and removes NVMe over Fabrics controllers. The default behavior is ownership-aware: only controllers with no entry in the ownership registry are disconnected. Controllers registered to an orchestrator (e.g. nvme-stas, nbft) are left untouched.

Use --owner to target a specific orchestrator’s controllers, or --force to disconnect all controllers regardless of ownership. --force and --owner are mutually exclusive. When either flag is used interactively a confirmation prompt is shown; non-interactive invocations proceed without prompting.

See the documentation for the [nvme-disconnect(1)](/man/os/nvme-cli/nvme-disconnect.1) command for further background.

# [OPTIONS](#OPTIONS)

-t &lt;STR&gt;, --transport=&lt;STR&gt;

Limit disconnection to controllers using the specified transport (e.g. tcp, rdma, fc).

--owner=&lt;NAME&gt;

Disconnect only controllers owned by NAME in the registry. Requires interactive confirmation when stdin is a terminal.

--force

Disconnect all controllers regardless of ownership. Requires interactive confirmation when stdin is a terminal.

# [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)

•Disconnect all unowned controllers (safe default):

```
# nvme disconnect-all
```

•Disconnect all controllers owned by nvme-stas:

```
# nvme disconnect-all --owner stas
```

•Disconnect all controllers regardless of ownership:

```
# nvme disconnect-all --force
```
