PROBLEM TO BE SOLVED: To provide a failover method in a computer system configured of a server to be booted from an external disk device for performing the failover of only a specific logical partition in a logical partition computer system in more detail. SOLUTION: In this computer system in which a plurality of servers are connected to an external disk device on a network, and a logical partition mechanism constructing one or more logical partitions is installed on the server, and an operating system is booted from the boot disk of the external disk device by the logical partition, when the failure of the server which is operating a task is generated, the failover of only the logical partition which is affected by the failure is operated. Thus, it is possible to achieve the detection of the failure generation of the server, the specification of the site of the failure, the specification of the logical partition which is affected by the failure from the site of the failure, the stop of the logical partition, the retrieval of a preserver being a takeover destination, the construction of the logical partition in the preserver, the takeover of the boot disk of the logical partition to the constructed logical partition, and the start of the constructed logical partition.
