nvme-disconnect-all(1)

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. 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). A command-line flag always overrides the file.
