Click on the Edit... button in the Controller dialog to open the Edit Controller dialog. Edit the information for the selected controller, or access related dialogs to add user data, change the physical description, arrange components within the controller, or group controllers into subsystems (for example, dual frame).
Note that if the Physically Installed check box is not enabled, the controller is un-installed, and drawn with dotted lines in the configuration diagram.
If the Devices are Integrated check box is enabled, all strings connected to the selected controller are integrated into the controller. Integrated strings and devices are not drawn in the configuration diagram, but can be accessed through the Edit menu or the Strings section of the Controller dialog. When you first create a controller, if its type is anything except DASD or Tape, it is automatically marked as devices are integrated.
The Display Class list box allows you to select a display class of the subsystem to which the controller belongs. The display class only affects the display by HCM of certain classes of controllers; the display class is initially set by HCM during IODF load/resync according to the first control unit added to the subsystem (see Filtering your view for details).
