# [DESCRIPTION](#DESCRIPTION)

Send a NVMe-MI Send command to the specified device, return results.

The &lt;device&gt; parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1).

On success it returns 0, error code otherwise.

The bare *nvme nvme-mi-send* form (without a space) still works as a deprecated alias and will be removed in a future major version. New scripts should use *nvme nvme-mi send* instead.

# [OPTIONS](#OPTIONS)

-O &lt;opcode&gt;, --opcode=&lt;opcode&gt;

The NVMe-MI opcode to send to the device in the command Required argument as this param is mandatory.

-n &lt;nsid&gt;, --namespace-id=&lt;nsid&gt;

The value for the ns-id in the command. The broadcast value 0xffffffff can also be given as *all* or *-1*.

-l &lt;data-len&gt;, --data-len=&lt;data-len&gt;

The data length for the buffer used for this command.

-m &lt;nmimt&gt;, --nmimt=&lt;nmimt&gt;

The value for the NVMe-MI message type in the command.

-0 &lt;nmd0&gt;, --nmd0=&lt;nmd0&gt;

The value for the NVMe management request dword 0 in the command.

-1 &lt;nmd1&gt;, --nmd1=&lt;nmd1&gt;

The value for the NVMe management request dword 1 in the command.

-i &lt;file&gt;, --input-file=&lt;file&gt;

If the command is a data-out (write) command, use this file to fill the buffer sent to the device. If no file is given, assumed to use STDIN.

# [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. Other versions are rejected.

--quiet

Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

--set-options=&lt;key=value&gt;\[,&lt;key=value&gt;...]

Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

--timeout=&lt;ms&gt;

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

# [EXAMPLES](#EXAMPLES)

•Has the program issue a nvme-mi-send to execute the VPD write.

```
# nvme nvme-mi send /dev/nvme0n1 -O 6 -m 1 -0 0 -1 0x100 -l 256 -i vpd.bin
```

# [NVME](#NVME)
