When all of SIOS Protection Suite’s comm paths are disconnected and if Automatic Node Failover is enabled, each side of SIOS Protection Suite assumes that the other side is dead and attempts to bring all the resources in service. In the case of a SIOS DataKeeper resource, both sides become mirror sources and allow data to be written to the volume.

Refer to the topic Split-Brain Recovery for the steps required to resolve this situation.
The Properties Panel for the selected volume displays additional information about the split-brain condition and instructions for resolving this problem.
