19.7 BUILDING A BACKUP SERVER

The relationship between the management server (the primary server) and the managed node is extended to other servers that will have responsibility for the node in the event of a primary server failure. The backup server should be installed following the standard OpenView Management server procedure.

19.7.1 OpenView Failover Concepts

If a failover or takeover becomes necessary it means that the primary server where the node normally sends its messages is no longer available to receive information from its managed nodes. A surrogate server must assume responsibility for the nodes. When the primary server is available, it must resume responsibility for the managed nodes. Therefore, both servers including the primary and all secondary servers must maintain consistent configurations to minimize the time it takes to failover and failback.
