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).

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.
