For the NVMe device given, issues the Zone Management Send command with the Set Zone Descriptor Extensions action. The input will default to stdin. Alternatively, the data may come from a file that can be specified. The data length will automatically be calculated from the zns identify namespace.
−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.
−r, −−zrwaa
Allocate Zone Random Write Area to zone.
−d <FILE, −data=<FILE>
Optional file for data (default stdin)
−t <timeout>, −−timeout=<timeout>
Override default timeout value. In milliseconds.
• 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 set−zone−desc /dev/nvme0 −n 1 −s 0
