Avoiding a partitioned cluster

Use care when using forced varyon to activate a volume group. If the cluster becomes partitioned, each partition might force the volume group to vary on and continue to run. In this case, two different copies of the data are active at the same time.

This situation is referred to as data divergence , and does not allow a clean recovery. If this happens in a concurrent volume group, the two sides of the cluster have made uncoordinated updates.
