Abstract: PROBLEM TO BE SOLVED: To efficiently manage a complicated set of high-availability resources by allowing a cluster system to support the resource group fail-over between two arbitrary nodes in a large-scale clusters of 2 nodes. SOLUTION: A cluster computer system 200 is provided so as to actualize the high availability of an NT-server-based application and Microsoft cluster service(MSCS) supports a fail-over function in a cluster of two nodes 202 and 204 and a common disk 208. If a resource gets out of order, MSCS restarts the faulty resource on a local node or moves the resource group to another node. Two nodes in the MSCS cluster have mutual heart beats 206, and if one node gets out of order, all resource groups are restarted on remaining nodes. After this fail-over event, the system is initialized.

Abstract: A clustered computer system provides both speed and reliability advantages. However, when communications between the clustered computers are compromised those same computers can become confused and corrupt database files. The present method and apparatus are used to improve the management of clustered computer systems. Specifically, the system expands the number of nodes available for failover conditions. Further, provision is made for returning the system to an initial state after a failover event.
