If the key specified in the Reservation key field is already registered but the initiator which registered the key is different from the initiator requesting the command, the drive returns RESERVATION CONFLICT status. If persistent reservation that is being attempted conflicts with persistent reservation that is held, the drive returns a RESERVATION CONFLICT status. The established persistent reservation applies to all commands received after the successful completion of the command. Release This service action may conflict with a successfully established persistent reservation. If the initiator requesting the command has not previously performed a Register service action, the command is rejected with a status of RESERVATION CONFLICT status. If the key specified in the Reservation key field is already registered but the initiator which registered the key is different from the initiator requesting the command, the drive returns a RESERVATION CONFLICT status. The drive returns GOOD status when a key specified in Reservation key field is not found. When the key is found but the scope is different from the registered scope or the type is different from the registered type, the command is rejected with CHECK CONDITION status. The sense key is set to ILLEGAL REQUEST and the additional sense data is set to INVALID RELEASE OF ACTIVE PERSISTENT RESERVATION. Preempt and Abort This service action does not conflict with a successfully established persistent reservation. If the initiator requesting the command has not previously performed a Register service action, the command is rejected with a status of RESERVATION CONFLICT. If the key specified in the Reservation key field is already registered but the initiator which registered the key is different from the initiator requesting the command, the drive returns a RESERVATION CONFLICT status. Even if the key specified in the Service Action Reservation key field is not registered, the drive makes new persistent reservation without preempting if it does not conflict with an existing persistent reservation. When the key is registered but reservation for the key is nothing yet and the new persistent reservation does not conflict with an existing persistent reservation, the drive makes new persistent reservation and clears the key and all commands from the initiator which was registered the key. When the key specified in the Service Action Reservation Key is cleared even if a reservation for the key is nothing yet, the drive makes UNIT ATTENTION condition for the initiator which was registered the key. The sense key is set to UNIT ATTENTION and the additional sense data is set to RESERVATION PREEMPTED. When PERSISTENT RESERVATION OUT command with this service action completes successfully, the Generation counter is incremented. Register and Ignore Existing Key This service action does not conflict with a successfully established persistent reservation. The key specified in the Reservation Key field is ignored, and a key specified in the Service Action Reservation Key is registered as new key, regardless of whether or not a key has been already registered.
