NAME
       nvme-resv-report - Send NVMe Reservation Report, parse the result

SYNOPSIS
       nvme [<global-options>] resv report <device>
                               [--namespace-id=<nsid> | -n <nsid>]
                               [--numd=<num-dwords> | -d <num-dwords>]
                               [--eds | -e]
                               [--raw-binary | -b]

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).

       The bare nvme resv-report form (without a space) still works as a
       deprecated alias and will be removed in a future major version. New
       scripts should use nvme resv report instead.

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.

GLOBAL OPTIONS
       The following options are defined at the top-level nvme command and are
       available to this subcommand:

       --dry-run
           Print the command that would be executed, but do not actually
           execute it.

       --no-ioctl-probing
           Disable probing for 64-bit IOCTL support.

       --no-retries
           Disable retry logic on transient errors.

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

       --output-format-version=<version>
           Select the output format version. Version 1 uses the original field
           naming, while version 2 (default) provides more consistent and
           script-friendly field names.

       --timeout=<ms>
           Set the timeout for the command in milliseconds.

       -v, --verbose
           Increase the level of detail in the output. May be specified
           multiple times to further increase verbosity.

       These options can also be set as machine-wide defaults in
       nvme-cli.conf(5). A command-line flag always overrides the file.
