       nvme resv-register <device> [--namespace-id=<nsid> | -n <nsid>]
                                     [--crkey=<crkey> | -c <crkey>]
                                     [--nrkey=<nrkey> | -k <nrkey>]
                                     [--rrega=<rrega> | -r <rrega>]
                                     [--cptpl=<cptpl> | -p <cptpl>]
                                     [--iekey | -i]

DESCRIPTION

       The Reservation Register command is used to register, unregister, or replace a reservation
       key.

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’.

       -k <nrkey>, --nrkey=<nrkey>
           New Reservation Key: If the Reservation Register Action is 000b (i.e., Register
           Reservation Key) or 010b (i.e., Replace Reservation Key), then this field contains the
           new reservation key associated with the host. For all other Reservation Register
           Action values, this field is reserved.

       -p <cptpl>, --cptpl=<cptpl>
           Change Persist Through Power Loss State: This field allows the Persist Through Power
           Loss state associated with the namespace to be modified as a side effect of processing
           this command.

       -a <rrega>, --rrega=<rrega>

           performed by the command.

       -i, --iekey
           Ignore Existing Key: If this bit is set to a 1, then the Current Reservation Key
           (CRKEY) check is disabled and the command shall succeed regardless of the CRKEY field
           value.

           Indicator option, defaults to 0.
