<p>PURPOSE: To prevent the reset state occurring in one zone from being automatically propagated to another zone by generating a reset signal only for each of zones in a multiple zone processing system. CONSTITUTION: In a fault tolerant computer system 10, zones 11 and 11' are simultaneously operating. Zones 11 and 11' have duplicate processing systems 20 and 20' respectively. Systems 20 and 20' have plural modules connected to each other. When a data processor having this constitution will be reset, the transaction sent on a data path at present is stored. Next, the state of a system to which reset is indicated is detected. When the reset state is detected, the reset signal is transmitted to a selected component through the data path to reset the selected component. Thereafter, the stored current transaction is sent again through the data path.</p> |
