Abstract

A system for implementing a failover policy includes a cluster infrastructure for managing a plurality of nodes, a high availability infrastructure for providing group and cluster membership services, and a high availability script execution component operative to receive a failover script and at least one failover attribute and operative to produce a failover domain. In addition, a method for determining a target node for a failover comprises executing a failover script that produces a failover domain, the failover domain having an ordered list of nodes, receiving a failover attribute and based on the failover attribute and failover domain, selecting a node upon which to locate a resource.

Claims

1. A system for implementing a failover policy comprising:

a cluster infrastructure for managing a plurality of nodes;

a high availability infrastructure for providing group and cluster membership services; and

a high availability script execution component operative to receive a failover script and at least one failover attribute and operative to produce a failover domain.

2. A method for determining a target node for a failover, comprising:

executing a failover script, said script producing a failover domain, said failover domain having an ordered list of nodes;

receiving a failover attribute; and

based on the failover attribute and failover domain, selecting a node upon which to locate a resource.
