The lowest failover priority integer value indicates the highest rank. For instance, when MC01=0 1 MC02=1 2 MC00=99 are defined on MC00 this indicates the failover priority order is "MC01 MC02 MC00'. In this case the TaskManager on MC00 runs "Suspend duty in Failover" Tasks when

1. MC00 is not Failed or
2. when MC01 and MC02 are Failed.

Three Master Controllers in a single synchronization pool with:

1. MC00 and MC01 both own Failover Tasks.
2. MC02 is not owning any Failover Tasks.
3. MC00 and MC01 take over Failover Tasks from each other when the other is in Failover or down.
4. MC02 has to take over Failover Tasks from MC00 and MC01 when MC00 and MC01 are down or failed over.

Each MC that is not in Failover mode can become top MC for Failover Tasks owned by other MCs as soon as no recent heartbeats (5 minutes threshold) are received from higher ordered remote MCs.
