<p>A reduction method comprises a step of detecting an abnormality of a first system common part (14a), a step of reading out priority information on whether or not the degeneration of the first system common part (14a) is performed from a storage part (23) if the abnormality thereof occurs for each partition part (D), a step of performing a stop processing for an information processor (10) if a system control unit (20) detects the abnormalities of the partition parts (D) where the priority information is set, and a step of stopping the operation of the first system common part (14a) and performing a reduction processing to switch to a second system common part (14b). As a result, if an important partition goes down due to a failure caused in a common part, a quick recovery can be achieved.</p> |
