Cluster components and assess common cause failures.
In the common cause failures view, you assess the possibility of two or mode nodes failing simultaneously. Most often, two nodes must be sufficiently close together before a single event can make both fail. For example, two equipment items in the same building will fail in a single area-wide power failure.
The common cause failure view does not have tabs for each service. Common cause failures are assessed for the project as a whole. This assessment is done once for each vulnerability, as long as that vulnerability occurs at least twice in the project. Vulnerabilities that occur only for a single node are not shown; for a common cause failure event to happen, at least two nodes must be involved.
