I have 3 Node cluster
Server1(primary) / Server2(replica) located in Chicago.
Server3(replica) Located in out of region.
I have 10 databases part of AG1 group.
Server1 to Server2 replication is Sync but to Server3 is ASYNC. I want to simulate a dr test where network links are going to be broken gracefully and ungracefull (2 scenarios
Scenario 1(gracefull network broken)
obviously the data movement has stopped. databases in AG1 group are required to read/write.
question1: how do I simulate network outage? I was thinking of stopping the cluster network resource - not sure if that possible.
question2: dbs in AG1 group are required to be in read/write state. what are my options for doing this and when Dr test is completed - during fallback - how do I reesrtablish AG data movement as those dBS were opened up for readwrite?/ I am guessing I need to remove the replica and re-add it?
Thanks!
