SharePoint 2013 App Server Failover
Posted on 2014-03-24
In the process of fail over testing of a new farm, my App servers seem to fail over correctly when I cleanly shut a server down (OS Shutdown).
However, when I test for fail over simply by disabling the network connection (via V Sphere), fail over does not work.
To clarify. I am testing fail over simply by using search. When I shutdown one of the two servers, search still produces results and the same when the other app server is cleanly shutdown.
While both servers are running, if I disconnect one from the network, I receive no results and the ULS log show a "Query time out error".
So the question, why does this happen and how can it be avoided? If anyone can shed some light on this it would be greatly appreciated.
