The Veritas High Availability Engine (HAD) may terminate unexpectedly when performing a group failover operation on a group containing an agent that logs messages directly into the Engine_A.log. For example, the Hitachi True Copy (HTC) or SRDF agents.
This could cause a failover to not happen as expected. For example, in the case of a failover due to a node failure, the Service Group may come back online on the original node rather than move to the target node.
