                        [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

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​.

-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​.

-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​.

-o <fmt>, --output-format=<fmt>

Set the reporting format to normal, json or binary​. Only one output format can be used at a time​.

-v,  --verbose

Increase the information detail in the output​.

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