NVME-SUBSYSTEM-RES(1) NVMe Manual NVME-SUBSYSTEM-RES(1)

nvme-subsystem-reset - Reset the nvme subsystem.

nvme [<global-options>] subsystem-reset <device>

Requests NVMe subsystem reset. The <device> param is mandatory and must be an NVMe character device (ex: /dev/nvme0).

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.
