Information processing apparatus, failure processing method, and recording medium in which failure processing program is recorded

A failure processing method in 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 method comprising:

• detecting, in each of the plural physical partitions, a failure occurrence in a hardware resource belonging to the physical partition corresponding to the failure notifying section and outputting the detection of the failure occurrence;
• detecting, on the basis of partitioned mode information indicating whether or not the information processing apparatus is operating in the partitioned mode, that the information processing apparatus is operating in the partitioned mode;
• determining, on the basis of hardware resource management information indicating whether the respective hardware resources are exclusively-used or shared in the partitioned mode of said information processing apparatus, whether or not the failed hardware resource is shared by two or more physical partitions;
• generating, if it is detected that the information processing apparatus is operating in the partitioned mode in the detecting and it is determined that the failed hardware resource is shared by two or more of the plural physical partitions in the determining, a single common failure report on the basis of the detections of the failure occurrences output from the two or more physical partitions;
• and
• if two or more detections of failure occurrences are output, determining whether the detections of failure occurrences are originated from a same failure, on the basis of information from the determining, and generating 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.

A computer-readable recoding medium in which a failure processing program is stored, said program instructing a computer 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, to execute:

• detecting, in each of the plural physical partitions, a failure occurrence in a hardware resource belonging to the physical partition corresponding to the failure notifying section and outputting the detection of the failure occurrence;
• detecting, on the basis of partitioned mode information indicating whether or not the information processing apparatus is operating in the partitioned mode, that the information processing apparatus is operating in the partitioned mode;
• determining, on the basis of hardware resource management information indicating whether the respective hardware resources are exclusively-used or shared in the partitioned mode of said information processing apparatus, whether or not the failed hardware resource is shared by two or more physical partitions;
• generating, if it is detected that the information processing apparatus is operating in the partitioned mode in the detecting and it is determined that the failed hardware resource is shared by two or more of the plural physical partitions in the determining, a single common failure report on the basis of the detections of the failure occurrences output from the two or more physical partitions;
• and
• if two or more detections of failure occurrences are output, determining whether the detections of failure occurrences are originated from a same failure, on the basis of information from the determining, and generating 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.
