8.13.5.1 Scope, Type
The Scope and the Type are applied in the process for the Reserve, Release, and Preempted and Abort
service action but they are ignored in the process for the Register service action because they are not
used.

The Reservation Key is verified in each service action process. If the initiator which registered a key is
different from the initiator requesting PERSISTENT RESERVATION OUT command, the drive returns a
RESERVATION CONFLICT status.
