Abstract

PURPOSE:To improve the availability of a system by providing a processor for generating a specific information at the time of detecting an error as a result of a self-diagnosis and a service processor for instructing the separation of the processor where the fault is generated to a normal processor. CONSTITUTION:The processors 12, 13 execute the self-diagnosis under the control of self-diagnosis control parts 18, 19 to decide whether they operate normally or not and for instance, the processor 12 where the fault is generated is decided to be an error and the operation thereof is stopped. Then, the service processor 17 is interrupted through a diagnosis interface 20 and a diagnosis interface bus 22 and the service processor 17 processes for separating the processor 12 where the fault is generated. Thereby, the processor 12 where the fault is generated is easily separated to improve the availability of the system.
