# nvme-nvme-mi-send(1)

Send a NVMe-MI Send command to the specified device

## NAME

nvme-nvme-mi-send - Send a NVMe-MI Send command to the specified device

## SYNOPSIS

```
nvme [<global-options>] nvme-mi send <device>
                        [--opcode=<opcode> | -O <opcode>]
                        [--namespace-id=<nsid> | -n <nsid>]
                        [--data-len=<data-len> | -l <data-len>]
                        [--nmimt=<nmimt> | -m <nmimt>]
                        [--nmd0=<nmd0> | -0 <nmd0>]
                        [--nmd1=<nmd1> | -1 <nmd1>]
                        [--input-file=<file> | -i <file>]
```

## DESCRIPTION

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

The \<device\> 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

- \-O \<opcode\>, --opcode=\<opcode\>

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

- \-n \<nsid\>, --namespace-id=\<nsid\>

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

- \-l \<data-len\>, --data-len=\<data-len\>

  The data length for the buffer used for this command.

- \-m \<nmimt\>, --nmimt=\<nmimt\>

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

- \-0 \<nmd0\>, --nmd0=\<nmd0\>

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

- \-1 \<nmd1\>, --nmd1=\<nmd1\>

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

- \-i \<file\>, --input-file=\<file\>

  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

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

## 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
```
