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
RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems.
The service processor may have recorded one or more symptoms in its error log.
Examine this error log before proceeding (see “System Information Menu” on
page 301). The system may have been set up by using the HMC. Check the Service
Action Event (SAE) log in the Service Focal Point. The SAE log may have recorded one
or more symptoms in the Service Focal Point. To avoid unnecessary replacement of the
same FRU for the same problem, it is necessary to check the SAE log for evidence of
prior service activity on the same subsystem.
The service processor may have been set by the user to monitor system 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
Eserver
pSeries 630 Model 6C4 and Model 6E4 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 conclusion 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 following table, 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 7, “Using the Service Processor” on page 283.
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.
