The "Reservation Key" field contains an 8-byte value provided by the application client to the device server to identify the initiator that is the source of the PERSISTENT RESERVE OUT command. The device server shall verify that the "Reservation Key" field in a PERSISTENT RESERVE OUT command matches the registered reservation key for the initiator from which the task was received, except for:

a)the REGISTER AND IGNORE EXISTING KEY service action where the "Reservation Key" field shall be ignored; and

b)the REGISTER service action for an unregistered initiator which shall have a reservation key value of zero.

Except as noted above, when a PERSISTENT RESERVE OUT command specifies a "Reservation Key" field other than the reservation key registered for the initiator the device server shall return a RESERVATION CONFLICT status. Except as noted above, the reservation key of the initiator shall be verified to be correct regardless of the "Service Action" and "Scope" field values.

The "Service Action Reservation Key" field contains information needed for four service actions; the REGISTER, REGISTER AND IGNORE EXISTING KEY, PREEMPT, and PREEMPT AND ABORT service actions. For the REGISTER and REGISTER AND IGNORE EXISTING KEY service action, the "Service Action Reservation Key" field contains the new reservation key to be registered. For the PREEMPT and PREEMPT AND ABORT service actions, the "Service Action Reservation Key" field contains the reservation key of the persistent reservations that are being preempted. The "Service Action Reservation Key" field is ignored for all other service actions.
