Good afternoon, all!
Working on validating an SQL HA setup. We have two SQL 2016 servers riding on Server 2012 R2 instances in VMware. The master server and the witness share are on one subnet, and the second server (with no witness) is on a second subnet in a remote datacenter.
I did some updates to the master server and rebooted; the cluster seems to have responded correctly and failed the primary replica database over to the second server. However, this will require a manual failback once the desired primary server comes back online. Is there a setting or a method to get an automatic failback? We would like this to happen to avoid problems with the application. Failing this, can this AlwaysOn be configured with both DB servers as peers? So that whichever server responds the transaction will replicate to the other one and automatically resolve any concurrency problems?
Thanks for looking!
