Abstract: A service AP conducting ordinary business processing is executed on a first OS. The first OS includes an operation recording controller for recording operation conducted by the first OS as operation recording information together with time when the operation is conducted, and an auxiliary driver for accepting and executing external processing. A multi-OS controller interface included in a second OS, which is higher in reliability than the first OS, operates a multi-OS controller from an AP operating on the second OS. An analysis and prediction AP operating on the second OS analyzes states of the first OS and the service AP, and detects a failure sign. Upon detecting a failure sign, degrade operation of the OS or service AP to be analyzed, preparations for switching from an active system to a stand-by system, and actual switching are conducted before the failure occurs.

Abstract: The management and reliability of communications between computers and a storage system are improved. As between the primary and secondary communication ports of storage devices 20a, 20b, the system management server 10 sets the primary communication port as the current communication port as a default setting in each storage device. Where the system management server 10 monitors the primary and secondary communication ports and the current communication port fails or can otherwise no longer be used, the other communication port is set as the current communication port. The system management server 10 also manages the states of each communication port and the setting of the current communication port as communication port information.

Abstract: The technique of the present invention enhances reading speed of data from a disk device in a computer system capable of transmission and reception of the data via a node device 200 between a client 100 and a storage device 300. A share volume PDc and specific volumes PDa and PDb are defined in the disk device on the storage device 300. Common data among respective clients and specific data corresponding to the individual client are stored in the share volume and specified volumes, respectively. Once respective clients request virtual volumes VDa and VDb to read the data, the storage device reads out the corresponding data from the share volume or the specific volume. This application avoids lowering the reading speed regardless of the concentration of accesses from a plurality of clients because most data can be read from the share volume.

With the main OS performing usual processing, the sub OS uses a test/maintenance program to check the operation of the repaired, replaced, or added hardware component and then passes the control of the hardware component to the main OS.

Abstract: A physical memory of a single computer is divided for each of a plurality of operating system (OS). A first OS is first loaded into the computer and runs. A multi-OS management program common to a plurality of OSs is incorporated into a virtual address space of the first OS as a device driver of the first OS. The multi-OS management program incorporated as the device driver is rearranged in a memory area shared by OSs so that the multi-OS management program has the same virtual address in any OS. In this state, the second OS program itself is loaded in the virtual address space of the second OS by execution of the multi-OS management program in the first OS. Execution of the multi-OS management program is switched from the multi-of management program in the first OS to the multi-OS management program in the second OS. Then, the second OS is started by execution of the multi-OS management program in the second OS to thereby run the plurality of OSs on the single computer.

Abstract: In provision against an unrecoverable failure in a first OS, a second OS for undertaking failure processing is loaded onto a memory beforehand. On detecting a failure in the first OS, a gate driver saves the first OS, moves the second OS to its executable area within the memory, and starts up the second OS. After this, control is transferred to a failure-processing application program placed under the control of the second OS.
