nvme-disconnect-all1
Disconnect from all connected fabrics controllers.
Usage
nvme [<global-options>]
disconnect-all
[{--transport=<STR> | -t
<STR>}]
[--owner=<NAME>]
[--force]
Overview
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.
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.
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
