nvme zns zone-mgmt-send <device> [--namespace-id=<NUM> | -n <NUM>]
                        [--start-lba=<IONUM>, -s <IONUM>] [--zsaso, -o]
                        [--select-all, -a] [--zsa=<NUM>, -z <NUM>]
                        [--data-len=<IONUM>, -l <IONUM>]
                        [--data=<FILE>, -d <FILE>]
                        [--timeout=<timeout> | -t <timeout>]

For the NVMe device given, issues the Zone Management Send command with the requested send action​. If the send requires additional data, you may specify the data length​. If data is required, the input will default to stdin​. Alternatively, the data may come from a file that can be specified​.

-n <NUM>, --namespace-id=<NUM>

Use the provided namespace id for the command​. If not provided, the namespace id of the block device will be used​. If the command is issued to a non-block device, the parameter is required​.

-s <lba>, --start-lba=<lba>

The starting LBA of the zone to manage send​.

-l <NUM>, --data-len=<NUM>

Send data buffer length

-o,  --zsaso

Zone Send Action Specific Option

-a,  --select-all

Send command to all zones

-z <NUM>, --zsa=<NUM>

Zone send action​.

-l <IONUM>, --data-len=<IONUM>

Buffer length if data required

-d <FILE>, --data=<FILE>

Optional file for data (default stdin)

-t <timeout>, --timeout=<timeout>

Override default timeout value​. In milliseconds​.

• Send a zone management command with action set to 1 (close zone) to namespace 1’s first zone:

  # nvme zns zone-mgmt-send /dev/nvme0 -n 1 -s 0 -z 1

• Write "hello world" into the zone descriptor for namespace 1’s first zone (requires device supports a large enough zone extended data)

  # echo "hello world" | nvme zns zone-mgmt-send /dev/nvme0 -n 1 -s 0 -z 0x10
