Figure: Example scenario 4: Resource with atleast resource dependency faults shows an example where the parent resource (R1) depends on five child resources (R2, R3, R4, R5, and R6). Out of these five resources, at least two resources must be online for the parent resource to remain online.

VCS tolerates the fault of R2, R3, and R4 as the minimum criteria of 2 is met. When R5 faults, only R6 is online and the number of online child resources goes below the minimum criteria of 2 and the fault is propagated up the dependency tree to the parent resource R1 and service group is taken offline.
