MAP 1020: Problem Determination
Purpose of This MAP
Use this MAP to get an error code if you were not provided one by the customer or you
are unable to load diagnostics. If you are able to load the diagnostics, go to MAP 0020
in the Diagnostic Information for Multiple Bus Systems.
The service processor may have recorded one or more symptoms in its error log. It is a
good idea to examine that error log before proceeding (see “System Information Menu”
on page 457).
Be prepared to record code numbers and use those numbers in the course of analyzing
a problem. Go to “Step 1020-1” on page 85.
The service processor may have been set by the user to monitor server operations and
to attempt recoveries. You may wish to disable these actions while you diagnose and
service the system. If the system was set up according to the recommendations of the
Enterprise Server S80 pSeries 680 Model S85 User’s Guide, all the settings of the
service processor (except Language) were saved by using the SAVE/RESTORE
HARDWARE MAINTENANCE POLICIES Service Aid. You may use that same Service
Aid to restore the settings at the end of your service action.
In case the service processor settings were not saved by the user, if you disable them,
make notes of their current settings for restoration before you leave.
In addition to the parameters in the table below, you may wish to disconnect the
modem to prevent incoming signals that could cause the model S80 and S85 to power
on.
Following are the service processor settings of your interest. The service processor
menus are described in “Chapter 7. Service Processor Menus” on page 447.
Surveillance From the service processor Setup Menu, go to
the Surveillance Setup Menu and disable
surveillance.
Unattended Start From the service processor System Power
Control Menu, disable unattended start mode.
Reboot Policy From the System Power Control Menu, go to
the Reboot/Restart Policy Setup Menu and set:
1. Number of reboot attempts to 0 (zero)
2. Use OS-Defined restart policy to No
3. Enable supplemental restart policy to No.
Call Out From the Call-In/Call-Out Setup Menu, go to
the Serial Port Selection Menu and disable
call-out on both serial ports.
