In this configuration both server - server A and server B - are primary server that protect active ClearCase components. Each server operates as a backup server for its cluster members.
Server A as primary server protects shared storage array for views and registry. Server B makes the backup.
Server B protects VOB as primary server, while server is it backup.
LifeKeeper monitors server functions and ClearCase processes and takes automated recovery action in case of failure. Client connections are seamlessly routed between nodes as needed to ensure constant availability of ClearCase operations to end-users.
