To delete one or more objects, click to select them in the diagram, and choose Delete from the Edit menu. Shortcut: press the DEL key after selecting the object. HCM will first disconnect the object and then delete it. If the Confirm on Delete option is on, HCM will ask you if you want to delete the object before actually deleting it. See Specifying options for more details.
You can use the Undo command immediately after a Delete to reverse it.
Most subobjects, such as partitions, segments, and interfaces (including paths) cannot be deleted from the diagram. You can delete subobjects by editing their containing objects. For example, to delete a CHPID, double-click on the appropriate processor, click on the CHPIDs... button, select the CHPID from the list box displayed, and press the Delete button.
Selecting an interface and pressing the DEL key will only disconnect it. This only applies to interfaces at the bottom of a connection: channel interfaces, string interfaces, crossbar channel interfaces, and upwards-facing switch ports.
Strings and units that are integrated into a controller are not visible in the configuration diagram. They can only be accessed through the Edit menu or in the Controller dialog. Select a string and press the Delete button in the Strings section of the Controller dialog; HCM will display a confirmation dialog before deleting the string.
Besides the possibility to delete multiple objects via selection on the configuration diagram, users can now select multiple objects on some Edit <object> dialogs and delete them in one step by pressing the Delete… button on these dialogs.
