We have a Active/Passive configuration and on Saturday, we had alarms that the replication partner was not reachable. So i click on the console of the primary server and it said "Network card is not accessible do you have some form of power saving enable, I am dazed and confused"

Ok so the network card had died in the primary server, so i deleted the binding between the servers and created a new bond with spare network cards that where in the servers. Recreated the partnership, recreated replication tasks but they would not start, i cleared the metadata but nothing would work, i even delete and recreated the destination volumes. It just kept saying already part of a replication task. So I built a new server and migrated the data across. What else could I have done to get this working correctly?
