                        [--namespace-id=<nsid> | -n <nsid>]
                        [--crkey=<crkey> | -c <crkey>]
                        [--rtype=<rtype> | -t <rtype>]

DESCRIPTION

The Reservation Release command is used to release or clear a reservation held on a namespace.

OPTIONS

-n <nsid>
--namespace-id=<nsid>

Override the nsid field. If using the admin character device, this parameter is required.

-c <crkey>
--crkey=<crkey>

Current Reservation Key: If the Reservation Register Action is 001b (i.e., Unregister Reservation Key) or 010b (i.e., Replace Reservation Key), then this field contains the current reservation key associated with the host. For all other Reservation Register Action values, this field is reserved. The controller ignores the value of this field when the Ignore Existing Key (IEKEY) bit is set to ‘1’.

-t <rtype>
--rtype=<rtype>

Reservation Type: This field specifies the type of reservation to be created.
