nvme-rpmb-read-config(1)

Usage

nvme [<global-options>] rpmb read-config <device> [{--msgfile=<data-file> | -f <data-file>}]

Reads the 512 byte device configuration block from RPMB target 0 of the NVMe device.

If --msgfile is not given, a summary of the boot partition protection and lock state is printed to STDOUT instead of the raw configuration block.

The <device> parameter is mandatory and an NVMe character device (ex: /dev/nvme0) must be specified.

-f <data-file>, --msgfile=<data-file>: Name of the file the read configuration block is written to. If an existing file is given, data is appended to it. If not given, a summary is printed to STDOUT instead.

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.

-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.
