Automatic verification system for maintenance/diagnosis facility in

Abstract

An automatic verification system for a maintenance/diagnosis facility in a computer system comprising a host computer and a service processor for performing maintenace/diagnosis of the host computer. The host computer includes a fault detecting facility and the service processor includes a fault cause analyzing/processing facility and a fault cause analysis data storing file. The fault cause analyzing/processing facility automatically retrieves on a software basis the fault cause analysis data with high efficiency and accuracy to improve accuracy and efficiency of the test. Through a multi-run of a verification program and a random sequence test program by which a variety of instruction strings based on a random sequence are generated and executed, faults generated at sophisticated timings inherent to a computer using acceleration logic adapted for parallel execution of a plurality of instructions can be simulated to realize a wide range of operation of the fault detecting facility and a wide range of verification for the fault cause analyzing/processing facility. With the above construction, the automatic verification system can efficiently perform automatic verification for the fault detecting facility and the fault cause service facility throughout the whole of the processing sequence.
