## 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.
