Abstract

PURPOSE: To collect fault information at good timing without providing any signal line other than a line for ordinary operation by recognizing a fault by informing software of the fault of a bus-connected low order device through a diagnostic bus and a diagnostic processor so as to generate interruption.
CONSTITUTION: The diagnostic bus 10 to connect an input/output processing device 3, the diagnostic processor 4 and input/output adapters 5 to 7 is provided, and a means to inform the diagnostic processor 4 of the fault by using the diagnostic bus 10 at the time of occurring the fault is included in the input/ output adapters 5 to 7. Besides, the means to collect the fault information of the input/output adapters 5 to 7 and simultaneously, inform a central processing unit 1 of this fault is included in the diagnostic processor 4. Then the diagnostic processor reads the status of the input/output adapter, and in the case of the fatal fault, it collects log information for fault analysis, and simultaneously, writes message information for checking the input/output adapter in a main storage device 2 so as to generate the interruption to the central processing unit. Thus, the fault information can be collected without providing any signal line other than the signal line to be used for the ordinary operation.
