SYNOPSIS

nvme nvme-mi-send <device> [--opcode=<opcode> | -o <opcode>]
                             [--namespace-id=<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.

OPTIONS

-o <opcode>
--opcode=<opcode>

The NVMe-MI opcode to send to the device in the command

-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.

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
