Abstract: A proposed fail over method for taking over task that is preformed on an active server to a backup server, even when the active server and the backup server have different hardware configuration. The method for making a backup server take over task when a fault occurs on a active server, comprises steps of acquiring configuration information on the hardware in the active server and the backup server, acquiring information relating the hardware in the backup server with the hardware in the active server, selecting a backup server to take over the task that is executed on the active server where the fault occurred, creating logical partitions on the selected backup server, and taking over the task executed on the active server logical partitions, in the logical partitions created on the selected backup server.

Abstract: The active server A101 notifies its own operating status to the administration server 106, and the administration server 106 acquires a snapshot and copies a disk according to the policy established by a user. When the active server A101 or the active disk 113 fails, the administration server 106 chooses a backup server A104 and a status storage disk A114 to be booted and restarts them by using the snapshot according to the policy.

Abstract: In a network computer system, recovery may be impossible from a fault when the fault occurs in a network switch in a network or a device such as an external disk device. Provided is a computer system that includes a plurality of servers, a plurality of network, a plurality of external disk devices, and a management computer, in which the management computer detects a fault which is occurred, retrieves an application stop server inaccessible to the used disk due to the fault, retrieves the disk for storing the same contents as contents stored in the disk used by the retrieved application stop server and the external disk device including the disk, retrieves an application resuming server capable of accessing the retrieved external disk device, and transmits an instruction to boot by using the retrieved disk to the retrieved application resuming server.

Abstract: A method for configuring failover environment, wherein the data on the configuration of the standby server device is obtained by transferring a program for obtaining configuration data to the standby server device; comparison is made in the configuration management table in the management server between the configuration of the standby server device and that of the working server device; and the working server device is started up by emulating the configuration lacking in the working server device by using the unit for emulating the server configuration when the configuration of the standby server device and that of the working server device are different from each other.

Abstract: There is disclosed a high speed switching method for a disk image delivery system fail-over. A management server sends a disk image of an active server in advance to a standby server. When receiving a report that the active server has failed, the management server judges whether or not it is possible for the standby server to perform the service of the failed active server based on service provision management server information held by the management server and if possible, instructs the standby server to perform the service of the active server. Even if the disk image delivered in advance is different from the disk image of the failed active server, switching of the service to the standby server can be performed more quickly through resetting the setting values of unique information and installing the additional pieces of software on the standby server by the management server than redelivering an appropriate disk image.

Abstract: A deployment method and system in the OS deployment software are disclosed in which the deployment is possible to server units having various hardware configurations. In a computer system, a disk image of a deployer server unit is managed by a management server and a deployee server unit is connected to the management server through a network. The hardware configuration information of the deployer server unit and a hardware configuration tolerance list obtained from a driver information file in the disk image are held in the disk image. In response to a deployment instruction from the user, the management server compares the hardware configuration of the deployer server unit with that of the deployee server unit, and by detecting the difference therebetween, changes the deployment method in accordance with the detected difference.
