If it finds that the primary server has recovered, the switchimmediately restores the communication with the primary server instead ofcommunicating with the secondary server, and at the same time restores the status ofthe primary server to active while keeping the status of the secondary serverunchanged.When both the primary and secondary servers are in active or block state, the switchsends messages only to the primary server.
