Abstract
A memory reconfiguration system now allows a guest's absolute storage space to be mapped to multiple discontiguous host absolute storage space. A multi-zone relocation facility is provided for relocating multiple zones of the memory of the computer system. A control program being executed in its data processing system to reconfigure storages that are assigned to guests when sufficient real addressing capability is not available to provide a range of holes in the host absolute addressing space. Memory can be reconfigured by a control program that allows main storage, and expanded storage associated with a guest's real storage to be mapped to multiple discontiguous areas of host absolute spaces. When sufficient real addressing is not available in the host absolute addressing space it allows expansion of the host absolute storage space that maps a guest storage. The system can be used in scalar, parallel and massively parallel computer systems having plural logical processors (LPARs).
