Abstract

PURPOSE:To correctly detect a fault of other computer system (CAS) even when a connector between the CASes by sending a signal representing the normality of its own CAS and information of the other CAS from each computer system so as to detect a fault of the other CASes. CONSTITUTION:A management program 111 existing in a CAS 11 uses information representing that its own CAS is normal and information representing it that the other CASes are operated normally to communicate it to CASes 12, 13 through inter-channel connectors 17, 19. This is applied similarly to the CASes 12, 13. If the connector 17 is faulty, since the information does not come from the CAS 12 for a prescribed time, the program 111 on the cAS 11 regards it as the faulty CAS 13. In this case, the program 111 checks the information from the CAS 13 and the CAS 13 recognizes it that the CAS 12 is discriminated to be normal and returns the information. The managing program 111 judges that the CAS 12 is normal based on the information sent from the CAS 13.
