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

Part of the nvme−user suite.
