ABSTRACT:
A method is provided which controls a data processing system having two common memories forming a duplex memory, a plurality of clusters provided in common for the common memories, and input/output paths connecting the clusters to the common memories. The method includes the steps of detecting a failure which has occurred in one of the common memories by each of the clusters, physically disconnecting input/output paths connected to the above-mentioned one of the common memories therefrom when the failure is detected by one of the clusters, and inhibiting the clusters from accessing the above-mentioned one of the common memories in which the failure has occurred. There is also provided a data processing system that uses such a method.
