You must assign the local system values to the SystemZones attribute of the application's service group. You set these values so that the service group fails over in the same zone before it tries to fail over across zones.

For more information about campus cluster setup, refer to the Cluster Server Administrator's Guide.

For example, you set up the service group's SystemZones attribute for two zones: 0 and 1. You want the service group on Node_A and Node_B to fail over between the two nodes before it comes up on Node_C and Node_D. The application and its fire drill service group both have the following values for the SystemZones attribute:

SystemZones = { Node_A = 0, Node_B = 0, Node_C = 1, Node_D = 1 }
