Synopsis
nvme resv-report <device> [–namespace-id=<nsid> | -n <nsid>]
[–numd=<num-dwords> | -d <num-dwords>]
[-b | –raw-binary]
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.
-b, –raw-binary
- Print the raw buffer to stdout. Structure is not parsed by program.
