METHOD AND SYSTEM FOR SEPARATING FAULT OF PCI BUS ERROR

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for separating a fault on a bus. SOLUTION: This method for separating a fault state on the bus of a computer system provided with an input/output (I/O) sub system 18 formed by plural input/output devices for performing communication through the bus includes repetitive classification of the input/output sub system 18 into a prescribed range and separation of the generation source of an error state inside the input/ output sub system 18. Further, the input/output sub-system 18 performs the communication through a peripheral component interconnection PCI bus 21. In the system, the computer system for separating the fault state on the PCI bus 21 is provided with a processing mechanism and an input/output mechanism connected to the processing mechanism. The input/output mechanism is provided with the plural input/output devices 20 and a bridge connected to the PCI bus 21 for performing the communication corresponding to a PCI standard. Further, this system is provided with a fault separating mechanism for identifying the generation source of the error state in the input/output mechanism inside the processing mechanism.
