Situation: We have an AlwaysOn High Availability group with 4 replicas (2 for DR) a listener and an FileShareWitness. I've been tasked with creating a set of instructions for patching all of the servers in the environment.
Problem: The plan has been based on Pinal Daves article (with some modifications). here
The problem is that when patching the FSW it switches back and forth between replicas.
A colleague has suggested removing the possible failover value from the ip (not from AOAG) to avoid the failover and then putting it back afterwards.
Please advise if this is good idea, or if there is a better way of stopping the AG replica from switching back and forth?
SQL is 2016 Enterprise SP1 running on WS2012R2 Datacenter 6.3 with Hypervisor
Any help will be much appreciated.
