## DESCRIPTION

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).

## OPTIONS

-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.
