Recover
Recover changes the primary Remote Copy groups on the target system to secondary groups and then starts and synchronizes all groups. Recover does not return the configuration to a prefailover state. To start data synchronization and immediately return to a prefailover state, perform a restore.
A recover operation:
Reverses the direction of replication.
Synchronizes the delta changes from the target to the source storage system for a Remote Copy group.
Changes the Remote Copy group Source role to Secondary-Rev.
Prevents hosts connected to the source system from having write access on the LUNs that are associated with the virtual volumes in the Remote Copy group.
