An attempt has been made to power on the system by a service processor
power-on with the IPL mode set to Manual. To correct the problem, set the IPL

This error can also occur if a power-off has been requested before a complete IPL
has occurred to initialize the time-of-day clock on the processor card.
The time-of-day clock can become "uninitialized" if the cable from the control panel
to the processor becomes disconnected or if there is a simultaneous loss of control
power and a bad or disconnected control panel battery.
