Failover processing in storage server system utilizes policies for managing
fault tolerance (FT) and high availability (HA) configurations. The approach encapsulates
the knowledge of failover recovery between components within a storage server and
between storage server systems. This knowledge includes information about what
components are participating in a Failover Set, how they are configured for failover,
what is the Fail-Stop policy, and what are the steps to perform when "failing-over"
a component.
