Defining service policy overrides

You define all service policy overrides from the service policy selection list. You can define three kinds of service policy overrides:

Override service class goals
Override resource group assignment
Override resource group attributes.

To override a service class goal, choose either the action code or the menu bar option to Override Service Classes. Figure 1 shows a service policy selection list where you have chose to override the service classes for the weekend policy.

Command ===> ____________________________________________________________

The application displays the Override Service Class Selection List panel. This is the list of all of your defined service classes, similar to the Service Class Selection list, except it has an extra field called Overridden Goal which indicates whether or not the service class goal or resource group assignment was overridden for that policy. Figure 2 shows an Override Service Class Selection List. Select a service class whose goal or resource group assignment you want to change and specify the action code or menu bar option to override the service class.

 Command ===> ______________________________________________________________

Start of change When you choose the override service class option, the application displays the Override Attributes for a Service Class panel. Figure 3 shows an Override Attributes for a Service Class panel. To override the goal, use the same codes to edit the goal as you do on the Create or Modify a Service Class panel. You can also change the Cpu Critical setting and the I/O Priority Group, just as you do on the Create or Modify a Service Class panel. To change the resource group assignment of the service class, either enter in a resource group name, or put a ? in the resource group field to select a resource group from the selection list. End of change

If you want to remove a service from a resource group, blank out the name.
