30 Netra SPARC T4-1B Server Module Service Manual • June 2012
You can also set other Oracle ILOM properties to control various other aspects of
POST operations. For example, you can specify the events that cause POST to run,
the level of testing POST performs, and the amount of diagnostic information POST
displays. These properties are listed and described in “Oracle ILOM Properties That
Affect POST Behavior” on page 30.
If POST detects a faulty component, the component is disabled automatically. If the
server module is able to run without the disabled component, it will boot when
POST completes its tests. For example, if POST detects a faulty processor core, the
core will be disabled. After POST completes its test sequence, the server module
boots and uses the remaining cores.
