Abstract: An information processing system includes a plurality of nodes and a shared memory connected to the plurality of nodes. Each of the nodes includes a plurality of functional circuits, a control device, and a register configured to store a plurality of interrupt factors that occur in the plurality of functional circuits. And The control device in one node among the plurality of nodes receives the interrupt factor in each register of a plurality of other nodes in response to an occurrence of the interrupt factor, extracts an interrupt factor to be detected as a failure among the received interrupt factors, specifies a fail node according to an extraction result, and, after suppressing access to the shared memory by the fail node, controls to separate the fail node from the information processing system on basis of log information received from the plurality of other nodes.

Abstract: A failure detecting device comprising a processor and a memory. The processor executes a process including storing propagation information indicating the other components to which the failure propagates, and a standby time for standing by until the failure propagates to the other components. The process includes detecting the failure of a component. The process includes acquiring, when a first failure was detected, propagation information about a detected component and a standby time about the detected component. The process includes determining notification candidates including a component in which a failure has been detected first and a component in which a new failure has been detected before the acquired standby time has elapsed. The process includes notifying, as a failed component from among the determined notification candidates a user of a component that is not included in the propagation information acquired at the acquiring after the standby time has elapsed.

Abstract: A part information restoration method is adapted to an electronic apparatus having first and second parts which are replaceable and are provided with a nonvolatile memory for storing part information unique to the part. The method includes storing, in a first nonvolatile memory of the first part, part information of the first part, and saving part information of the second part as a first reference information at least when replacing the second part, storing, in a second nonvolatile memory of the second part, the part information of the second part, and saving the part information of the first part as second reference information at least when replacing the first part. The method restores the first reference information in the second nonvolatile memory or restores the second reference information in the first nonvolatile memory, after replacing the first or second part.

Abstract: An electronic apparatus system includes a plurality of racks mounting a plurality of electronic apparatus. The system identifies the physical location of the electronic apparatus having sent the abnormality notification by using light emitting devices displaying the statuses of the electronic apparatuses. The light emitting devices of the entire electronic apparatuses on a rack is displayed, and the rack location is identified from among a plurality of racks.

Abstract: Automated update to the firmware of the optimum version can be performed when a system board is exchanged, etc. When a system board is exchanged, a version change unit compares the version of the firmware of the system board with the version of the firmware of the corresponding partition stored in the partition-specific version storage unit. When they do not match, the version of the firmware of the system board is updated to the same version stored in the partition-specific version storage unit.

Abstract: A failure information management method manages failure information related to a replaceable part of an electronic apparatus, by generating an error log, and storing the error log in a non-volatile memory of the replacement recommended part itself. The error log is generated by recording first generation information in a representative log information part and detailed log information part in a non-overwritable manner with respect to a first failure of a replacement recommended part, and by recording second generation information in the representative log information part and the detailed log information part in an overwritable manner with respect to second and subsequent failures of the replacement recommended part.

Abstract: A cooling control apparatus controls a plurality of cooling members. The apparatus has a monitor which monitors states of predetermined combinations of the cooling members and a controller which controls the cooling members based on the states monitored by the monitor.

Abstract: One of processors connected effectively to a system is allocated to a master processor and the other remaining processors are allocated to slave processors. Each processor compares the self processor number of a processor number register and the processor number of the other processor of a processor effective register. For example, when the self processor number is smallest as compared with the other processor numbers, it is recognized that the self processor is a master processor. A master initialization diagnosing process after completion of the allocation is monitored by the slave processor. When an abnormality of the master processor is recognized, a degeneration to disconnect the master processor from the system is executed and is again reconstructed by the allocating process of master/slaves. Even when an abnormality occurs in the master processor, the operation in which the system was degenerated can be executed until the minimum construction in which two or more processors normally operate.

Abstract: A device for the initial-diagnosing of processors is provided with a processor module, a storage unit, an address allocation unit and a diagnostic execution unit. The processor module has a processor and a cache storage unit. The storage unit stores an initial diagnostic setting program which diagnoses the processor and the cache storage unit. The address allocation unit allocates the addresses of the processor by making the addresses of the processor correspond to the addresses of the cache storage unit so that the cache storage unit is accessed by the processor. The diagnostic execution unit reads the initial diagnostic setting program stored in the storage unit into the addresses of the cache storage unit allocated by the address allocation unit, and executes the initial diagnostic setting program.

Abstract: A method of detecting defective memory locations by determining a slot number corresponding to a memory address, when read data disagree with written data, determining a memory size corresponding to the determined slot number, determining relationships between data bit positions and memory module numbers according to the determined memory size, determining a memory module number as an abnormal memory according to the determined relationships, and specifying the slot number and the memory module number of the abnormal memory. Based on the specified slot number and memory module number, the defective memory module at the slot number can be quickly located and removed.
