Description

  The present invention relates to factor analysis when a system failure occurs in a computer system.

  In a conventional computer system, when an OS (operating system) cannot operate normally due to a system failure, dump processing means for collecting failure information for factor analysis operates. The dump processing is to acquire data on a main storage device such as a memory when a system failure occurs and save it as a dump file in an auxiliary storage device such as a hard disk. The dump file saved by the dump processing means is mainly used by a person in charge of analysis for failure analysis.

  By the way, generally, when a system failure occurs due to a hardware failure, failure information is recorded not in the memory but in a status register that is provided in each hardware and stores the hardware status. For this reason, the analysis of the dump file cannot identify the failed hardware, and can only identify it by examining the operation of the hardware one by one.

  Since the computer system is composed of a large number of hardware including a memory, a plurality of hard disks, an arithmetic processing unit, an input device, a display device, a DVD drive, a plurality of PCI devices, etc., even a skilled analyst can It took a long time to check the hardware operation one by one, and it took a lot of time to restore the system.

  The dump file is written as binary data, and the user cannot directly recognize the failure information in the dump file. Therefore, in order for the user to refer to the data in the dump file, special software and specialized knowledge about failure analysis are required, and general users have to ask a system maintenance person etc. to perform failure analysis. There wasn't.

  The problem to be solved by the present invention is to provide a computer system that can automatically identify and notify a user of hardware that has failed when a system failure occurs due to a hardware failure.

In order to solve the above problems, the present invention includes a plurality of hardware including a main storage device and an auxiliary storage device, and each of the plurality of hardware includes a status register for storing the status of the hardware. In the system, when a system failure occurs, the register information is acquired from the status register, the faulty hardware is identified from the register information, the failure information is generated, and the location on the main storage device for storing the failure information a dump file by dump processing unit denoted by the identification information together with the identification information failure information from and stored in the main storage device for identifying the a system failure analysis, identification information by searching the dump file system failure processing means reads and outputs failure information subjected in the region of the main memory that is recorded is recorded Characterized by comprising providing.

  According to the present invention, after the failure information is generated and stored in the main storage device, the dump file is generated by the dump processing means. Therefore, when the system failure is analyzed, the failed hardware is automatically detected by searching the dump file. The user can be identified and notified and the time to system recovery can be shortened.

Also, when a system failure occurs, register information is acquired from the status register , and identification information for specifying the position on the main storage device for storing the register information is attached, and the register information is stored together with the identification information in the main storage device. A dump file is generated by the dump processing means after being stored in the file, and when the system failure is analyzed, the dump file is searched and the register information recorded in the area on the main storage where the identification information is recorded is recorded. It may be configured to provide system failure processing means for reading out and identifying the hardware that has failed from the register information and outputting the failure information, and the location where the failure information is generated may be changed.

  Embodiments of the computer system of the present invention will be described below with reference to the drawings.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a configuration diagram of a computer system according to this embodiment. As shown in FIG. 1, the computer system according to the present embodiment includes a memory 2 and a hard disk 4, and a plurality of hardware units including an arithmetic processing unit, an input unit, a display unit, a DVD drive, a plurality of PCI devices, etc., not shown. Each piece of hardware has a status register that stores register information 6 indicating the status of the hardware.

  Further, the OS 10 of the computer system according to the present embodiment generates a dump file 41 from the system failure processing unit 12 that operates when a system failure that causes the OS 10 to stop operating and the data stored in the memory 2 is generated. And a dump processing unit 14 for storing in the hard disk 4.

  Furthermore, a failure information management function 18 and a failure location automatic notification function 16 are provided on the OS 10. The failure information management function 18 operates when a system failure occurs, and the failure location automatic notification function 16 operates when the system is activated. It is like that.

  The failure information management function 18 includes a register information acquisition unit 20, a failure location analysis unit 24, and an identification information addition unit 26.

  A procedure for automatic notification of failure location information when a system failure occurs in the computer system of this embodiment configured as described above will be described with reference to FIGS. FIG. 2 is a flowchart showing the processing flow of the OS 10 when a system failure occurs in this embodiment.

  When a system failure occurs due to a hardware failure, the system failure processing unit 12 which is a part of the OS 10 starts processing (S11). The system failure processing unit 12 calls a failure information management function 18 described later (S12), and waits for the end of the processing of the failure information management function 18 (S13). When the processing of the failure information management function 18 is completed, the dump processing unit 14 starts processing, generates a dump file 41 from the data stored in the memory 2 and stores it in the hard disk 4 (S14). When the storage of the dump file 41 is completed, the OS 10 restarts (S15).

  FIG. 3 is a flowchart showing a processing flow of the failure information management function 18. When a system failure occurs, the failure information management function 18 called by the system failure processing unit 12 of the OS 10 starts processing of the register information acquisition unit 20. The register information acquisition unit 20 acquires register information 6 indicating normality / abnormality of hardware at the time of system failure from a status register included in each hardware (S21).

  Thereafter, the failure location analysis unit 24 finds out the acquired register information 6 having a value indicating an abnormality, and specifies data that can identify the failed hardware, for example, a character string of the hardware name. 21 (S22). The identification information adding unit 26 adds identification information 23 for specifying a position on the memory 2 to the failure location information 21 (S23). At this time, the identification information 23 to be added is a unique value such as a proper noun that cannot be found otherwise in the search in the dump file 41.

  Next, the failure location information 21 and the identification information 23 are stored in an area on the memory 2 from which the dump processing unit 14 acquires data (S24). When the process of the identification information adding unit 26 is completed, the process returns to the system failure processing unit 12 of the OS 10, and the failure location information 21 and the identification information 23 stored in the memory 2 are generated by the dump processing unit 14. Remains recorded.

  FIG. 4 is a flowchart showing a process flow of the failure location automatic notification function 16. When the failure location automatic notification function 16 starts processing by restarting the OS 10 in FIG. 2 (S15), first, the identification information 23 is searched from the dump file 41. If the identification information 23 is not recorded, the processing ends. (S31). When the identification information 23 is recorded, the failure location information 21 recorded on the area where the identification information 23 is recorded is read (S32). The read failure location information 21 is recorded in a log or outputted to a display device (S23). The user confirms the output fault location information 21 and responds for system recovery.

  As described above, according to the present embodiment, since the dump file 41 is generated by the dump processing unit 14 after the failure location information 21 is generated and stored in the memory 2, the dump file 41 is stored in the system failure analysis. By searching, the failed hardware can be automatically identified and notified to the user, and the time until system recovery can be shortened.

  Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a configuration diagram of the computer system in the case where the fault location is specified after the OS 10 is restarted. In this embodiment, the failure location analysis unit 24 of the failure information management function 18 is moved to the failure location automatic notification function 16 in the configuration of the first embodiment, and other configurations are the same as those of the first embodiment. Since the processing flow of the OS 10 in this embodiment is the same as that in FIG. 2, the processing flow of the failure information management function 18 and the failure location automatic notification function 16 will be described with reference to FIGS.

  FIG. 6 is a flowchart showing a processing flow of the failure information management function 18. When the failure information management function 18 is called by the system failure processing unit 12 of the OS 10 when a system failure occurs, the failure information management function 18 starts processing of the register information acquisition unit 20. The register information acquisition unit 20 acquires the register information 6 indicating the normality / abnormality of the hardware at the time of system failure from the status register (S41).

  Next, the identification information adding unit 26 adds identification information 23 for specifying a position on the memory 2 to the register information 6 (S42). Thereafter, the register information 6 and the identification information 23 are stored in an area on the memory 2 from which the dump processing unit 14 acquires data (S43). When the process of the identification information adding unit 26 is completed, the process is returned to the system failure processing unit 12 of the OS 10, and the register information 6 and the identification information 23 stored in the memory 2 remain recorded in the dump file 41.

  FIG. 7 is a flowchart showing a processing flow of the failure location automatic notification function 16. When the failure location automatic notification function 16 is started by restarting the OS 10, the identification information 23 is first searched from the dump file 41. If the identification information 23 is not recorded, the process is terminated (S51). If the identification information 23 is recorded, the register information 6 recorded in the area where the identification information 23 is recorded is read (S52). The failure location analysis unit 24 finds a value indicating an abnormality from the read register information 6 and identifies the failure location (S53). Thereafter, the identified failure location is recorded in a log or the like or output to the display device (S54). In the present embodiment, the same effect as that of the first embodiment can be obtained.

  As described above, the first and second embodiments have been described. However, the present invention is not limited to these and can be applied by appropriately changing the configuration. For example, when multiple computer systems are connected via a network, when a system failure occurs in one computer system and there is no abnormality in the network, the fault location information can be output to another computer system via the network.
