Claim:
A failover cluster system in which a plurality of computers are connected and failover object resources of a failover source computer are taken over by a failover target computer, comprising a control section that takes over said failover object resources in stepwise fashion in accordance with a priority ranking set for said failover object resource, wherein said priority is set by the state of use of said failover object resource; wherein each of said computers employs a shared memory device to share takeover information relating to takeover of said failover object resources and said control section can thus take over said failover object resources in stepwise fashion in accordance with said priority ranking, by referring to the takeover information of said shared memory device; wherein said takeover information is constituted by associating information for specifying said failover object resources with takeover processing actions set for said failover object resources in accordance with said priority ranking; wherein said priority ranking includes a first ranking whereby takeover processing is immediately executed and a second ranking whereby takeover processing is executed when an access request for said failover object resources is generated.
