# [NAME](#NAME)

nvme-rpmb-write-config - Write the RPMB device configuration block

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] rpmb write-config <device>


                        [--msgfile=<data-file> | -f <data-file>]


                        [--msg=<data> | -d <data>]


                        [--keyfile=<key-file> | -g <key-file>]


                        [--key=<key> | -k <key>]
```

# [DESCRIPTION](#DESCRIPTION)

Writes 512 bytes of device configuration block data to RPMB target 0 of the NVMe device, authenticated with the key previously programmed with *nvme rpmb program-key*.

The &lt;device&gt; parameter is mandatory and an NVMe character device (ex: /dev/nvme0) must be specified.

# [OPTIONS](#OPTIONS)

-k &lt;key&gt;, --key=&lt;key&gt;, -g &lt;key-file&gt;, --keyfile=&lt;key-file&gt;

Authentication key previously programmed with *nvme rpmb program-key* for target 0. The key can be specified on the command line using --key or -k, or read from a file using --keyfile or -g.

-f &lt;data-file&gt;, --msgfile=&lt;data-file&gt;

Name of the file the configuration block data is read from.

-d &lt;data&gt;, --msg=&lt;data&gt;

Provides the configuration block data directly on the command line, instead of reading it from a file.

# [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.

# [EXAMPLES](#EXAMPLES)

•Write configuration data block from config.bin file

```
# nvme rpmb write-config /dev/nvme0 -f config.bin -k 'SecretKey'
```

# [NVME](#NVME)

Part of the nvme-user suite
