The Reservation Report command returns a Reservation Status data structure to host memory that describes the registration and reservation status of a namespace.

The size of the Reservation Status data structure is a function of the number of controllers in the NVM Subsystem that are associated with hosts that are registrants of the namespace (i.e., there is a Registered Controller data structure for each such controller).

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

Retrieve the reservation report structure for the given nsid. This is required for the character devices, or overrides the block nsid if given.

-d <num-dwords>, --numd=<num-dwords>

Specify the number of Dwords of the Reservation Status structure to transfer. Defaults to 4k.

-c <cdw11>, --cdw11=<cdw11>

The value for command dword 11. Setting bit 0 specifies that the controller returns the Extended Data Structure.

-b, --raw-binary

Print the raw buffer to stdout. Structure is not parsed by program.

-o <format>, --output-format=<format>

Set the reporting format to normal, json, or binary. Only one output format can be used at a time.
