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.
