Have you tried deleting all the RDEVs and recreating? It sounds like CP has not correctly sensed the devices as being part of an ATL. The devices need to be online when CP IPLs in order to determine they are part of an ATL.
As for the manual mount, maybe what they are referring to is something directly at the ATL. Best Regards, Les Geer IBM z/VM and Linux Development >This is a new processor and a new ATL.
