+NAME
+----
+nvme-resv-report - Send NVMe Reservation Report, parse the result
+
+SYNOPSIS
+--------
+[verse]
+'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>]
+
+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 <format>::
+--output-format=<format>::
+ Set the reporting format to 'normal', 'json', or
+ 'binary'. Only one output format can be used at a time.
