NAME

nvme-ocp-clear-fw-activate-history - Clear the OCP Firmware Update History Log

SYNOPSIS

nvme [<global-options>] ocp clear-fw-activate-history <device>


                        [--no-uuid | -n]

DESCRIPTION

For the NVMe device given, Clear OCP Firmware Update History Log.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1).

This command with no option added, will try to automatically detect the parameters of the command. This will work successfully or fail gracefully for devices supporting UUID for Vendor Specific Information (NVMe 1.4 or later, OCP 2.0 requires NVMe 1.4b). For devices that do not support OCP 2.0 the command will fail gracefully, unless the --no-uuid option is provided.

For OCP 1.0 devices (before NVMe 1.4) the --no-uuid option is required. When --no-uuid option is provided, results for devices before NVMe 1.4 without OCP support are undefined.

On success it returns 0, error code otherwise.

OPTIONS

-n, --no-uuid

Do not try to automatically detect UUID index for this command (required for old OCP 1.0 support)

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.
