A lack of console activity can be no messages appearing on the
console or no response by the system to commands. Causes can be simply
a low level of system activity or a problem in message processing
in the operating system.
- If a full-capability console appears inactive, check the system
response by requesting a display of the time. Enter a DISPLAY T command.
The system should respond within a few seconds with the time and
date.
- Take the console out of hold mode (see Temporarily suspending the screen roll for more details).
- If it does not, enter a CONTROL C,D command to cancel any status
displays being presented on the unresponsive console.
The
console should return to normal activity.
- If it does not, assume the console has some other problem. Do
the following:
- Enter a CONTROL Q command to delete messages that
are queued to the console, but have not yet been displayed. These
messages have already been through hardcopy processing.
- Check for a console hardware error.
- If possible, bring up another console and enter
a RESET CN command for the unresponsive console.
- Notify the system programmer.
- If necessary, reIPL the system, following normal procedures.
