Changing control unit attachment parameters for multiple processors

You can change control unit (CU) attachment parameters or attach a control unit for a group of processors. If all parameters to be changed are identical, use the following group action.

1. On the Control Unit List, select a control unit that is attached to the group of processors and use the Change action from the context menu (or action code  c ).
2. On the Change Control Unit panel press the Enter key. HCD then displays a Select Processor/Control Unit panel with a list of processors already defined (see Figure 54).
3. Select the processors for which you want to change the control unit-processor definitions and use the Group change action from the context menu (or action code  g ).
4. The Change Control Unit Definition panel is displayed showing the values/attributes for the first processor in the group. An * in the Processor ID field indicates that you are using the Group connect action from the context menu and the changes will be applied to more than one processor.
