If you can sign on to an alternative console, do the following:
Make sure the primary console controller (for example, CTL01) and device
description (for example, DSP01) have been created or restored. To check the
device description, use the command WRKCFGSTS *CTL.
If descriptions exist, check the system operator message to determine
why the primary console failed.
Take corrective actions indicated in the message.
If you still cannot solve the problem, set the system to the Normal mode
and call your hardware service provider.
If you cannot sign on to an alternative console,
perform a manual IPL by following these steps:
Set the system to Manual mode.
Select function 3 and press Enter. The IPL Option display is shown.
Were you able to get to the IPL Option display?
No: Contact your next level of support or your
hardware service provider.
Yes: Continue with the next step.
To access the Configuration Commands menu, perform the following
steps on the IPL Options display:
Specify Y (Yes) in the Define or change system at IPL field
Specify N (No) in the Set major system option field and press Enter.
To see the controller description for the console, select option
2 (Controller description commands).
Verify that the controller was created correctly (for example, CTL01).
