Abstract:
1. An information processing apparatus operable in a partitioned mode in which hardware resources are exclusively-used or shared by a plurality of physical partitions and at least two of the plural physical partitions operate as independent partitions, said apparatus comprising: a partitioned mode information storage section that stores partitioned mode information indicating whether or not said information processing apparatus is operating in the partitioned mode; a hardware resource management information storage section that stores hardware resource management information indicating whether the respective hardware resources are exclusively-used or shared in the partitioned mode of said information processing apparatus; a plurality of failure notifying sections, provided for each of the plural physical partitions, each of the failure notifying sections detecting a failure occurrence in a hardware resource belonging to the physical partition corresponding to the failure notifying section and outputs the detection of the failure occurrence; an operation mode detecting section that detects, on the basis of the partitioned mode information stored in said partitioned mode information storage section, that said information processing apparatus is operating in the partitioned mode; a shared hardware resource determining section that determines, on the basis of the hardware resource management information stored in said hardware resource management information storage section, whether or not the failed hardware resource is shared by two or more of said plural physical partitions; and a common failure report generating section that generates, if said operation mode detecting section detects that said information processing apparatus is operating in the partitioned mode and said shared hardware resource determining section determines that the failed hardware resource is shared by two ore more of said physical partitions, a single common failure report on the basis of the detection of failure occurrence output by said notifying section in each said physical partition, wherein, if two or more of the failure notifying sections output detections of failure occurrences, the common failure report generating section determines whether the detections of failure occurrences are originated from a same failure, on the basis of information from the shared hardware resource determining section, and generates the single common failure report by merging failure occurrences output by each physical partition sharing the failed hardware resource by logical ORing the failure occurrences output by each physical partition sharing the failed hardware resource, if it is determined that the detections of failure occurrences are originated from a same failure.
