Physical Unit Naming Conventions

When creating a source (SRC) or source group (SGP) record, you must follow specific naming conventions. Naming conventions for graphics, logical devices, and VTAM devices are explained in the following sections.

Graphic Devices

GRAFccuu

Specifies terminals attached to the CPU

GRAF

Specifies a four‑character constant to define a terminal

ccuu

Specifies a four‑character device address that defines a terminal

Logical Devices

Although we support rule writing for logical devices, it is difficult to protect them. This is because logical device numbers are assigned at random and can become unpredictable. In future releases, we will use CA‑VTERM to pass the physical device name (GRAFxxxx) to CA ACF2 for VM. This enhancement lets CA ACF2 for VM users protect by physical input sources.

LDEVldevname

Specifies the logical device name

LDEV

Specifies a four‑character constant to define a logical device

ldevname

Specifies a four‑character logical device name

VTAM Devices

Luname

Specifies a VTAM logical unit name

luname

Specifies an eight‑character logical unit name
