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.
−e, −−eds
Request extended Data Structure: If this bit is set to a 1, then 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.
