We have an AlwaysOn High Availability Group set for Asynchronous/Manual failover (it's required by client). It is SQL Server 2016 running on Windows Server 2012 R2. It is set up as a 2 node Windows Failover Cluster. We are required to do a monthly update
for Windows Update patching. As you know, the manual failover requires human intervention using Microsoft's Rolling Update solution. We'd like to automate those failover steps with power shell, code, batch files, or some other combination of implementations.
Do you think this is feasible? Is it best just to do it manually (using SSMS and Failover Cluster Manager) because there are too many "gotchas"? I didn't want to start down the road of writing some program to do this if someone
has already been down this road and ran into too many problems. Thanks!
