Abstract
A recovery leg in a Star or Star-A configured data replication system is maintained in a pseudo-active RCVY mode in which personalities of corresponding replicas of a mirror are set to R1 on both sides of the recovery leg, capture cycles are performed, and transmit cycles are discarded. During a recovery operation, tracks are marked for resynchronization in the proper direction and resynchronization is performed if the source side data is not the most recent. Group-level personalities of the replica on the target side of the recovery leg are then set to R2 (the target side multi-session consistency software instance converts the capture cycles to restore cycles, converts the transmit cycles to receive cycles, and swaps the cycle tags between the receive and restore cycles). The RCVY mode and multi-session consistency software instances accelerate transition from RCVY mode to normal operation on the recovery leg.
