POST Overview

POST is a group of PROM-based tests that run when the server is powered on or when it is
reset. POST checks the basic integrity of the critical hardware components in the server.
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
described in
If POST detects a faulty component, the component is disabled automatically. If the server is
able to run without the disabled component, the server boots when POST completes its tests.
For example, if POST detects a faulty processor core, the core is disabled, POST completes its
test sequence, and the server boots using the remaining cores.
