MAP 1020: Problem Determination

diagnostics. If you are able to load the diagnostics, go to MAP 0020 in the
RS/6000 and

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 724). The server 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.
If you find any error codes in the service processor error log or the Service Focal Point, record all error
codes and any location codes in the order you find them and process each error code and location code
beginning at the Entry MAP. Otherwise, continue with the directions for MAP 1020.
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 670 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 709.
Surveillance
From the service processor Setup Menu, go to the
Surveillance Setup Menu and disable surveillance.
(Surveillance is automatically disabled in LPAR mode.)
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. (Call-out is automatically disabled when the system
is booted to operate with multiple partitions (also known
as a
partitioned system
).
Be prepared to record code numbers and use those numbers in the course of analyzing a problem. Go to
“Step 1020-1” on page 121.
