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

# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#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 &lt;device&gt; 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](#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 &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

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=&lt;ms&gt;

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)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.
