How VCS handles resource faults

This section describes the process VCS uses to determine the course of action when a resource faults.

VCS behavior when an online resource faults

In the following example, a resource in an online state is reported as being offline without being commanded by the agent to go offline.

If the Monitor returns an online status, VCS considers the resource online and resumes periodic monitoring. If the monitor returns an offline status, the resource is faulted and VCS takes actions based on the service group configuration.
