Follow these steps to restore the communication between the
system controller and printer:
1. Press the Continue button on the printer control console if
directed to do so.
If the printer responds and resumes printing, do not follow
the rest of this procedure.
2. If the printer does not respond and resumes printing, enter
the RESET command at the keyboard.
Note: Make sure that the system is varied offline from the
host before doing this.
3. Enter the PSC command. This should put the printer back in
communication with the system controller.
Ask your service representative to make this command a
logon level 2, otherwise, you cannot access it.
4. Retry the command. If the printer still does not respond,
inform your supervisor or a service representative.
A system rollover is a recovery technique the system uses to
initiate a restart following a fatal error. This error may be induced
by either a software or hardware failure.
Follow these steps to recover from a system rollover:
1. If your system is in an online configuration, the system
displays the following message:
OS2576 System rollover while online. Check host then enter
'C'
Enter C to initiate the recovery procedure. From this point
on, the recovery procedure is the same for online and offline
systems.
2. Print the abort data for analysis.
The system displays the following message:
System recovery from xxx abort Task = xxx
Print abort data for later analysis (y/n)?
a. After this message, the system displays a series of register
values and flag settings. Record these values for review
by your analyst.
b. Enter Y and give the resulting printout to your system
administrator or your site representative.
3. Make a backup copy of the abort data.
Your system may display the following message:
COPY COREIM.SYS TO MEMSAV.SYS (Y/N)?
