AS/400, S/38 and PS/2 as T2.1 Nodes in a··Subarea Network4.4 Definitions on the S/38 (RAL V38A)
When you configure an S/38 to communicate with the AS/400 behind the S/370 subarea network you need to create the following:
• A line description from the S/38 to the host.
• A control unit description for the S/370 on the S/38.
• A device description for the AS/400 on the S/38.
• A mode description for the device.
• A communications entry in the subsystem you are using for the device.
For information on setting up OSPT on the S/38 refer to 5138 CPF Programmer's Guide.
4.4.1 Create Line Description
To configure the S/38 to the network you must first create a line description from the S/38 to the S/370 host. You can do this by entering the CL command CRTLINO

4.4.3 Create Device Description
The device description contains the characteristics of the logical device (LU) on the S/38 that the remote system will communicate with. This device (LU) will be used to communicate with the AS/400 behind the subarea network. Use the command CRTDEVD
+
CMD 4 for prompting.Figure 46. Create Device Description Prompt
The device description name in Figure 46 is RAONN. This is an arbitrary name and doesn't have to match any other parameters.
The device address is 000061, where the first two digits indicates the inde-pendent Lu support. It is possible to create more devices with "00" as the first two digits to the same controller. Digits three and four have to match the first two digits of controller description address and digits five and six have to match the port address of the line to be used.
P24020C3 is the name of the controller to which this device is attached.

In Figure 47 you are required to define your local and remote LU names. The local LU name is RAOTNNCO and must match the LU name defined in the NCP LU macro to communicate with the S/38. The remote LU name defines the location (LU) with which it wants to communicate and therefore must match the local location name which resides in the local location list of the AS/400.
Because the communication will use the host as an intermediate system the remote LU name must also match the LU name for the AS/400 in the VTAM switched major node.

Figure 50. Add Communications Entry Prompt
To be able to use this device description for communications to the AS/400 you must add a communications entry in a subsystem on the S/38. We are using the subsystem name QSNADS for the device RAONN. To add your device to the subsystem you use the CL command ADDCMNE. You must make sure the subsystem is not active. If it is active you can enter the TRMSBS command.
This will terminate your subsystem so you can make the necessary changes.
Once you have added your communications entry you activate the subsystem again by using the STRSBS command. For more details on how to setup a communication environment on the S/38 see 5138 Control Program Facility Pro-grammers Guide.
