Abstract
A configuration control system for changing a system configuration of a data processing system. The configuration control system has a plurality of clusters and at least one global storage unit. Each of the clusters has a channel processing unit, at least one central processing unit, at least one main storage unit, a memory control unit and a service processor. The at least one global storage unit has the plural clusters in common. The configuration control system includes a first configuration control device for holding connection information of each unit in a cluster; and a second configuration control device for holding configuration control information of the global storage unit and the cluster. The second configuration control device controlled independently to the first configuration control device. The system also includes a device for generating a specific order for writing the configuration control information to the second configuration control device; and a device for setting a corresponding bit of the second configuration control device to a connection state when a bus between the global storage unit and the cluster is set to the connection state by the first configuration control device. The connection configuration between the global storage unit and the cluster designated by the first configuration control device is automatically set to the second configuration control device, and the second configuration control device is controlled independently to the first configuration control device based on the specific order.
