IPLing Stand-Alone Services

This topic lists the steps to IPL the Stand-Alone Services program. The programming status word (PSW) wait-state codes (encountered during Stand-Alone Services processing) are found in Interpreting wait-state codes. An example of the Stand-Alone Services system IPL is included in IPL example.

To IPL from the Stand-Alone Services core image (created with the BUILDSA command), proceed as follows:

1. Load the Stand-Alone Services Program.

   Load Stand-Alone Services from the processor’s IPL console by specifying the IPL address for the device (card, tape, or DASD) that contains the IPL-able core image and then, by performing a Load Clear operation (also referred to as an IPL Clear).

2. Select the Operator Console.
   When the Stand-Alone Services program has finished loading, one of the following conditions exist:

   • If the Stand-Alone Services core image was created without specifying the OPERCNSL keyword, then the processor enters a wait-state with the rightmost bytes of the PSW containing FFFFFF. Press the Enter key on the operator console you are using. The first interrupt presented is expected to be a console and is treated as such.
   • If the Stand-Alone Services core image was created with the OPERCNSL keyword specified, then Stand-Alone Services attempts to use the device address specified by OPERCNSL as the operator console, rather than waiting for the first interrupt. See Running stand-alone services with a predefined console for more information.
3. Specify the Input Device.
   After the operator console is identified, the following message is displayed:

    ADRY005E  DEFINE INPUT DEVICE, REPLY ‘dddd,ccuu’ or ‘CONSOLE’

   To specify the operator console as the input device, enter CONSOLE or a null line. To specify a different device type, enter dddd,ccuu, where dddd is either the device type or card, and ccuu is the unit address. For example, to select a 3505 card reader at address 502, enter:

       card,502

   The input device can be one of the supported console devices or a card reader device.

4. Specify the Message Output Device.
   After the input device is identified, the following message is displayed:

    ADRY006E  DEFINE OUTPUT DEVICE, REPLY ‘dddd,ccuu’ or ‘CONSOLE’

   To specify the operator console as the output device for operator communication, enter CONSOLE or a null line. To specify a different device type, enter dddd,ccuu, where dddd is either the device type or prnt, and ccuu is the unit address. For example, to select a 3800 print subsystem at address 510, enter:

       prnt,510

   The output device can be a supported console device or a supported printer device.

5. Specify the correct date and time, if needed.
   Stand-Alone Services automatically picks up the time and date from the processor’s time-of-day (TOD) clock, usually in the Greenwich Mean Time (GMT) format. When the TOD clock is incorrect or is not set, the following message is displayed:

    ADRY015E  SUPPLY TODAY’S DATE, REPLY ‘MM/DD/YY’

   When you have entered the correct date in the format indicated, the following message is displayed:

    ADRY016E  SUPPLY TIME OF DAY, REPLY ‘HH:MM:SS’

   Enter the correct time in the format indicated. If you press Enter without specifying a date or time, the value is set to zero.

At this point the IPL is complete. You can now enter Stand-Alone Services commands from the specified input device. Multiple commands can be entered without requiring a re-IPL of the Stand-Alone Services program.
