Using the Service Processor
• Processor Configuration/Deconfiguration Menu
This menu allows the user to change the system processor configuration. If it is
necessary to take one of the processors offline, this menu allows you to deconfigure a
processor, and then reconfigure the processor at a later time. An example of this menu is
shown below:

Note: This table is built from vital product data collected during the last boot sequence.
The first time the system is powered up, or after the system’s non–volatile RAM
(NVRAM) has been erased, this table may be empty. The table is rebuilt during the
next boot into AIX.
The fields of the previous table represent the following:
Column 1 (1.) Menu selection index.
Column 2 (0) Logical processor device number assigned by AIX. You can display these
logical device numbers by issuing the command lsdev –C | grep proc on the AIX
command line.
Column 3 (3.0) Processor address list used by the service processor and should be
ignored.
Column 4 (00) Error status of the processors.
The error status of the 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. 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.
