Abstract

PURPOSE:To allow an output device to output fault information by reading out fault log information from a storage means even when a fault is generated in a disk storing the fault log information. CONSTITUTION:When a hardware fault is generated in a processor 7 out of plural processors 1 to 7, a hardware fault detecting means 170 sends fault information to a maintenance diagnostic device 10 through a diagnostic bus 9. At the time of writing the fault information in a log information storing means 330, a storage means fault detecting means 400 judges the normality/abnormality detection of the means 300 by a storage means fault detection judging part, and when the means 300 is abnormal, informs storage means fault detection to a reading means 500. Then a log information storing means reading part for reading out the fault information from a log information storing means 600 is executed and the fault information is outputted to an output device 700.
