Check out the preonline_ipc trigger in the /opt/VRTSvcs/bin/sample_triggers directory. Copy this to the triggers directory, rename it preonline. Then turn on the attribute for preonline in the service groups. You can read thru the trigger, essentially it looks to see if there is an ip address in the SG, if so it pings for it, if it is up somewhere, SG does not come up. If it does not get a response, it checks to see if the system is isolated. If it is isolated (NICs down) then it does not bring up the SG.
The only option for panic that I know of is when you reconnect after an event like you experience, but that is too late.
