IBM 6H0, Service Manual

The error status of each processor is indicated by AB, where B indicates the number
of errors and A indicates the type of error according to the following table:
1. Bring-up failure
2. Run-time non-recoverable failure
3. Run-time recoverable failure
A status of 00 indicates that the CPU has not had any errors logged against it by the
service processor.
To enable or disable CPU Repeat Gard, use menu option 77. CPU Repeat Gard is
enabled by default.
If CPU Repeat Gard is disabled, processors that are in the
deconfigured by system
state will be reconfigured. These reconfigured processors are then tested during the
boot process, and if they pass, they remain online. If they fail the boot testing, they
are deconfigured, even though CPU Repeat Gard is disabled.
The failure history of each CPU is retained. If a processor with a history of failures is
brought back online by disabling Repeat Gard, it remains online if it passes testing
during the boot process. However, if Repeat Gard is enabled, the processor is taken
offline again because of its history of failures.
Note: The processor numbering scheme used by the service processor is different
from the numbering scheme used by AIX. Consult the AIX documentation
before configuring or deconfiguring a processor to ensure that the correct
processor is selected.
The AIX Documentation library is available at the following Web address:
http://www-1.ibm.com/servers/aix/library/. Select Technical Publications . AIX
documentation is also contained on the AIX Documentation CD. The
documentation is made accessible by loading the documentation CD onto the
hard disk or by mounting the CD in the CD-ROM drive.

Memory Configuration/Deconfiguration Menu
These menus allow the user to change the system memory configuration. If it is
necessary to take one of the memory DIMMs offline, this menu allows you to
deconfigure a DIMM, and then reconfigure the DIMM at a later time.
When this option is selected, a menu displays, showing the memory riser cards in
the system. Type the number of the memory riser card on which the DIMM is
plugged that you want to configure or deconfigure. An example of this menu is shown
below:
MEMORY CONFIGURATION/DECONFIGURATION MENU
77. Enable/Disable Memory Repeat Gard: Currently Enabled
1. Memory riser card 1
2. Memory riser card 2
98. Return to Previous Menu
Note: If there is only one processor in the system, system memory may reside on
that processor assembly. In that case, you are given the option to select the
processor card from the list.
