Computer and memory inspection method

A memory inspection method in a computer having a processor, a memory connected to the processor, and an I/O device connected to the processor,

• wherein the memory stores a system software that realizes a system control unit for controlling the overall computer, and an inspection program that realizes an inspection unit for inspecting whether a memory fault is present in the memory, or not,
• wherein the processor has a memory fault notifying unit that notifies the system control unit of a fault address which is an address of the memory at which the memory fault occurs when detecting the memory fault,
• wherein the system control unit includes:
• a plurality of event processing units that process the event occurring while the system control unit is operating, with the use of different storage areas of the memory;
• and
• inspection result information for holding results of the memory inspection executed by the inspection unit on the storage areas of the memory used by the respective plurality of event processing units, the method comprising:
• a first step of determining whether the inspection program needs to be executed, or not, on the basis of the type of an event occurring during the operation of the system control unit, by the system control unit;
• a second step of specifying any one of the event processing units using a storage area of the memory including the fault address by the system control unit if the memory fault is detected by the memory inspection;
• a third step of recording the memory fault in the specified event processing unit in the inspection result information by the system control unit;
• and
• a fourth step of selecting any event processing unit to process the event from the plurality of event processing units using a storage area of the memory in which the memory fault does not occur, with reference to the inspection result information, by the system control unit.
