Sun Cluster 3.1 Concepts Guide

Failover Services

Failover is the process by which the cluster automatically relocates a service from a failed primary node to a designated secondary node. With failover, Sun Cluster software provides high availability.

When a failover occurs, clients might see a brief interruption in service and might need to reconnect after the failover has finished. However, clients are not aware of the physical server that provides the service.
