Running stand-alone services with a predefined console

Use the OPERCNSL keyword of the BUILDSA command to predefine the console when creating the Stand-Alone Services program. The OPERCNSL keyword allows you to specify the address of the device to be used as the operator console, or you can specify OPERCNSL(SERV) to use an ES/9000 service console.

The device must also be a valid device within the configuration that is running the Stand-Alone Services program. DFSMSdss performs limited validation of the OPERCNSL keyword during the BUILDSA processing. This is because the Stand-Alone Services program may be run with a system configuration different from the one that is used to build the core image with the BUILDSA command. (The core image is the executable module that is loaded into the processor’s storage during IPL).

After it is IPLed, Stand-Alone Services attempts to use the predefined device as the operator console instead of waiting for the first interrupt to identify the operator console. If a problem with the predefined device is detected, the processor enters a wait-state with the rightmost bytes of the PSW containing "DDDDDD". This PSW indicates that Stand-Alone Services is unable to use the predefined device and is waiting for the operator to identify another console to be used as the operator console. If this happens, do the following:

Determine the cause of the problem with the predefined device and take steps to correct the problem. Some of the possible reasons for a problem being detected are listed below.
Generate an interrupt on a different console that you can use as the operator console.

The following are some of the reasons for a problem being detected with the predefined console:

An error has occurred during the Stand-Alone Services program’s initial communication with the predefined console.
The console address may have been incorrectly specified when the Stand-Alone Services program IPL-able core image was built. For example, the address that was specified with the OPERCNSL keyword of the BUILDSA command does not exist in the configuration in which the Stand-Alone Services program is being IPLed.
The device at the address specified with the OPERCNSL keyword cannot be identified as a supported operator console.
If the console was predefined to be the service console, the necessary features may not exist on the processor for Stand-Alone Services to communicate with the console.
