NVME-RPMB-INFO(1)                 NVMe Manual                NVME-RPMB-INFO(1)

NAME
       nvme-rpmb-info - Print RPMB support information for the controller

SYNOPSIS
       nvme [<global-options>] rpmb info <device>

DESCRIPTION
       For the NVMe device given, print information regarding supported RPMB
       targets, and access and total sizes, as reported in the RPMBS field of
       the Identify Controller data structure.

       The <device> parameter is mandatory and an NVMe character device (ex:
       /dev/nvme0) must be specified. If the given device does not support any
       RPMB targets, an error is printed instead.

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.

EXAMPLES
