    When you down a system, the service group fails over and then it gets autodisabled.  When the downed system comes back, VCS is the very last thing to start (i.e rc script is S99) and when it starts it probes all the resources and this can take a minute and then it autoenables servicegroup once all resources are probed successfully.

    So your issue is probably than you are downing the box too soon after it comes up, before the probes have finished - so you need to check this with "hastatus -sum" before downing the box.

Mike,

The test in question is when we pull the power on the active box and not a service group failure. Once power is restored to the system, the same action is performed on the second system (the one that was failover too) without any checking of the system that went out. They are expecting it to failover to the original system again.
