NVME-NVME-MI-SEND(1)

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.

-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.

--timeout=<ms>
    Set the timeout for the command in milliseconds.

-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). 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
