Working with generics

Device types with similar characteristics are logically grouped together and assigned a name to by the system. Such a group is called a generic device type. Reference to a generic device type is made by its name. To request a device allocation, a user can specify a generic device type rather than a specific device number. z/OS or OS/390 then allocates a device from the specified generic device type.

1. On the Primary Task Selection panel, select Define, modify, or view configuration data and on the resulting panel the object Operating system configurations. HCD displays the OS Configuration List of all operating system configurations currently defined in the IODF.
2. On the Operating System Configuration List, select the OS configuration and the Work with EDTs action from the context menu (or action code s ). HCD displays the EDT List.
3. To change the generics, select either the action Work with generics by name from the context menu (or action code  g ), or the action Work with generics by preference value (or action code  p ) on the EDT List. On the resulting panels you can then change the VIO indicator, the preference value for a generic, and you can display a subsequent panel that lists the devices belonging to the specific generic.
