Always testing I am. Here is what happens when I am connected to the web gui (OA and VC) at the same time as the VCSU :
I then go to the standby OA's web gui (becasue I do not have access to the real thing right now), I transition it to active and wait for it to reload. During all this time I cannot ping the current Active OA's ip until it is in transitionned to Standy.
