I have 3 servers in my Exchange 2013 deployment with 2 being the primary database holders for my 2 active databases and the 3rd server being a failover for either. One of my databases is now activating itself on the failover even after I manually activate it back on its primary holding server.
I am not seeing any events or warnings that would cause this so I am somewhat perplexed as to why the DAG is shifting it off to the failover. I have verified that the activation preference numbers for the database on the 2 servers is set correctly and that there is not an issue with low hard drive space.
