Cause: Between RHEL 6.1 and RHEL 6.2, a regression occurred that resulted in the Intel Modular and IF MIB fencing agents being removed from the list of devices for which users could configure new instances.
Consequence: Users could not create a new instance of an Intel Modular or IF MIB fencing device. They would still have been able to make changes to existing entries.
Fix: The Intel Modular and IF MIB fencing device entries have been added back to the list of fence devices.
Result: Users are again able to create new instances of Intel Modular and IF MIB fencing devices.
