Table 5-117PERSISTENT RESERVATION OUT Parameter List-Field Descriptions

Data Field	Description
	This field contains an 8-byte token that is provided by the application client to the device server
	to identify which initiator is the source of the PERSISTENT RESERVATION OUT command.
Reservation Key	The device server verifies that the Reservation Key in the PERSISTENT RESERVATION OUT
	command matches the Reservation Key that is registered for the initiator from which the com-
	mand is received. If there is no match, the device server returns a RESERVATION CONFLICT
	status. The Reservation Key of the initiator is valid for all Service action and Scope values.
	This field contains information needed for 3 service actions: the Register service action, the Pre-
	empt service action, and the Pre-empt & Clear service action. The Service Action Reservation Key
	is ignored for all other service actions.
	For the Register service action, the Service Action Reservation Key field contains the new Reser-
Service Action	vation Key to be registered.
Reservation Key	For the Pre-empt and the Pre-empt & Clear service actions, the Service Action Reservation Key
	contains the reservation key of the persistent reservations that are being pre-empted. For the Pre-
	empt and the Pre-empt & Clear actions, any failure of the Service Action Reservation Key to
	match any registered keys results in the device server returning a RESERVATION CONFLICT
	status.
	If the Scope is an Extent reservation, this field contains the Logical Block Address of the extent
	and the Extent Length field (bytes 22 – 23) contain the number of blocks in the extent.
Scope-Specific	If the Scope signifies an Element reservation, the Scope-Specific Address field contains the Ele-
Address	ment Address, zero-filled in the most significant bytes to fit the field; the Extent Length is set to 0.
	If the Service action is Register or Clear, or if the Scope is a Logical Unit reservation, both the
	Scope-Specific Address and Extent Length fields are set to 0.
	Activate Persist Through Power Loss. This bit is valid only for Register service actions; it is ig-
	nored for all other types of service actions.
	Support for APTPL set to 1 is optional. If a device server that does not support APTPL receives a
	1 in that bit in a Register service action, it returns a CHECK CONDITION status, with the sense
APTPL	key set to ILLEGAL REQUEST and additional sense data set to INVALID FIELD IN PARAM-
	ETER LIST.
	If the last valid APTPL bit value received by the device server is 0, the loss of power in the target
	releases any persistent reservations and removes all reservation keys. If the last valid APTPL bit
	value is 1, the logical unit retains all persistent reservations and all reservation keys for all initia-
	tors even if power is lost and later returned. The most recently received valid APTPL value from
	any initiator governs the logical unit’s behavior in the event of a power loss.
