# nvme-disconnect-all(1) Manual Page

## 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) 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.

--timeout=<ms>

  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). 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
