You can also change the failover order for your resources by modifying the Preferred
Owners list in the Modify Preferred Owners window, which is accessed through
Cluster Administrator. If some of your cluster nodes lack the resources to handle the
additional workload of a failover application, rather than using the “Cascading failover”
order (node 1—> node, 2—> node 3—> node 4), you can change the failover configu-
ration to a preselected order of cluster nodes.
For example, if you know that node 2 and node 3 have ample resources to handle one
application and nodes 1 and 4 are borderline, you can configure that application with
this failover order: node 2—> node 3—> node 1—> node 4.

To modify the failover sequence of the disk groups, perform the following steps:
1. Click the Start button and select Programs—> Administrative Tools—> Cluster

arrows on the right side of the window.
