SYNOPSIS

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

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.

   -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 <fmt>, --output-format=<fmt>
       Set the reporting format to normal, json or binary. Only one output format can be used at a time.

   -v, --verbose
       Increase the information detail in the output.

   -t <timeout>, --timeout=<timeout>
       Override default timeout value. In milliseconds.
