Is that probable? If someone played with the PPRC definitions, they could have reversed the primary/secondary relationship, making your volumes the secondaries. You can't write to a secondary. But I would certainly have expected messages on the operator's console if that happened. If this happened, then you break someone's fingers. GDPS breaks and restores PPRC connections only in synchronization with various flavors of CP HYPERSWAP commands. Humans or other solutions are expected to do the same.
