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

SYNOPSIS

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

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.

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.

-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.

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
