314 Logical Partitions on System i5
A processor is marked deconfigured under the following circumstances:
򐂰 If a processor fails built-in self-test or power-on self-test testing during boot (as determined
by the service processor).
򐂰 If a processor causes a machine check or check stop during run time, and the failure can
be isolated specifically to that processor (as determined by the processor run-time
diagnostics in the service processor firmware).
򐂰 If a processor reaches a threshold of recovered failures that results in a predictive call to
the service provider (as determined by the processor run-time diagnostics in the service
processor firmware).
The deconfiguration policy also provides the user with the option to manually deconfigure a
processor or re-enable a previous manually deconfigured processor.
To begin the process, you will use a panel similar to the one shown in Figure 10-54. Select the
processing unit you want to work with (one or more processing units may be shown) and click
the Continue button. You should get a panel similar to Figure 10-55.
