MAP 1020: Problem Determination
Purpose of this MAP
Use this MAP to get an error code if you were not provided with one by the customer or
you are unable to load diagnostics. If you are able to load the diagnostics, go to MAP
0020 in
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 258).
Be prepared to record code numbers and use those numbers in the course of analyzing
a problem.
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
26F/80,
256/F0, and 256/F1 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 same service aid to restore the settings at the
end of your service action.
If 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 Models 25F/80, 256/F0, or 256/F1 to
power on.
Following are the service processor settings. The service processor menus are
described in Chapter 7, “Using the Service Processor” on page 245.
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.
