If you are to use the Continuous Access Journal Z pair for delta resync operation as the master
journal after a power supply error occurred at the primary storage system, first resynchronize
the pair and then execute I/O operation from the host.
After the delta resync operation (when pair status has changed to Duplex), the delta resync
