Map 1020: Problem Determination - IBM RS/6000 Enterprise Server M80 Service Manual

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: Problem Determination Procedure"
in the RS/6000 and Eserver pSeries Diagnostic Information for Multiple Bus Systems.
The service processor may have recorded one or more symptoms in its error log. If the system has
attempted to boot since an error terminated normal operation, there may be specific fault information in the
service processor error log. Examine this error log before proceeding (see "System Information Menu" on
page 372).
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 M80, Eserver pSeries
660 Model 6M1 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 the same
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, 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. The service processor menus are described in Chapter 8,
