# nvme-disconnect-all(1)

Disconnect from all connected Fabrics controllers.

## NAME

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

## SYNOPSIS

```
nvme [<global-options>] disconnect-all
                        [--transport=<STR> | -t <STR>]
                        [--owner=<NAME>]
                        [--force]
```

## 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)](/nvme-disconnect/1.md) command for further background.

## OPTIONS

- \-t \<STR\>, --transport=\<STR\>

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

- \--owner=\<NAME\>

  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

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 \<fmt\>, --output-format=\<fmt\>

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

- \--output-format-version=\<version\>

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

- \--quiet

  Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

- \--set-options=\<key=value\>\[,\<key=value\>...\]

  Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

- \--timeout=\<ms\>

  Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

- \-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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## 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
```
