Hard/Severe failure on a synchronized primary controller triggers a switchover to the backup controller. The I/O modules associated with the controller force their outputs to safe values. If capable, the failed controller reboots into the FAIL state and captures diagnostic data which may contain internal state events that occurred prior to a failure. The Ctools utility can be used to retrieve the diagnostic data. 

Hard/Severe failure on a backup controller causes a loss-of-synchronization. The Primary controller continues operation, but enters the 'Not synchronized' state. If the redundant controller pair was not synchronized when the fault occurred, then the failed controller reboots into the FAIL state, if capable. No further synchronization will occur and no switchover occurs.
