To combat this, I wrote some code to only clear faulted 
non-infrastructure resources.  On my clusters, application failures are 
usually transient and you're better off trying to restart rather than 
failover to other node.

This code snippet is a little old and after looking at it, I found a bug 
wherein if you do have a faulted infrastructure resource you should 
probably execute an hagrp -switch.

if ($WhyOnlining eq "FAULT") {
     # Find any faulted resources...
     foreach $res ( @{VCS::Trigger::FaultedResources($SG, $System)} ) {
         # ...and verify they are a non-infrastructure resource...
         unless (VCS::Trigger::InfrastructureResource($res)) {
             # ...and clear the fault
             VCS::Trigger::ClearFault($res, $System);
         }
     }
}
..
VCS::Trigger::OnlineNoPre($SG, $System);
