nvme resv-report <device> [--namespace-id=<nsid> | -n <nsid>]
                        [--numd=<num-dwords> | -d <num-dwords>]
                        [-b | --raw-binary]
                        [-o <fmt> | --output-format=<fmt>]


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.
-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.
