Quantum ATL SuperLoader Software Interface Guide
The following table illustrates which fields are set by the
application client and interpreted by the device server for each
Service and Scope value.
Scope-Specific
Address
Ignored.
APTPL
Activate Persist Through Power Loss. This bit is valid only for Register and
Register and Ignore Existing Key service actions; it is ignored for all other
types of service actions.
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 initiators 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.
