How does VCS cluster work?
VCS continuously monitors and communicates events between clusters. In the event of a system or application failure, VCS fails over the Oracle service group to another system in the same cluster. If the entire cluster fails, VCS fails over the service group to the remote cluster, which is part of the global cluster.

When a system is down to a single heartbeat connection, VCS can no longer discriminate between the loss of a system and the loss of a network connection. This situation is referred to as jeopardy. If the system loses the last interconnect link, VCS places the service groups running on the system in autodisabled state.
How do I stop VCS clustering locally?

Where to find the VCS engine and agent logs?
The VCS engine and agent logs are normally found under /var/VRTSvcs/log. The name of the engine log is “engine_A.log.” Each agent log is named for its resource type. As an example, the agent log for DiskGroup agent is “DiskGroup_A.txt.” For the IP agent, the log file is “IP_A.log.”
