We have a 2 server SQL 2012 cluster (Active/Passive). When we first built this about 2+ years ago, the failover from one node to the other would only take around 20 to 30 seconds worst case.
Now it seems after 2 years of use and a whole bunch of sql updates/patches it's taking upwards of 6 minutes to fail over to the other node and during that time apps are not able to connect to sql at all.
I was wondering if anyone else has experienced something similar and found a solution to speed up the failover back into the 20 second range? thanks
