MAP 1020: Problem Determination
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 Diagnostics 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 382).
The service processor may have been set by the user to monitor server operations and
to attempt recoveries. You can disable these actions while you diagnose and service
the system. If the system was set up according to the recommendations of the RS/6000
Enterprise Server Model H80 Eserver pSeries 660 Models 6H0 and 6H1 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 can use
that service aid to restore the settings at the end of your service action.
Just in case the service processor settings were not saved by the user, if you disable
them, you should make notes of their current settings for restoration before you leave.
In addition to the parameters in the table below, you can disconnect the modem to
prevent incoming signals that could cause the system to power on.
Following are the service processor settings of your interest. The service processor
menus are described in Chapter 7, "Using the Service Processor" on page 369.
Surveillance
Unattended start
Reboot policy
Call out
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.
