POST Overview

POST is a group of PROM-based tests that run when the server module is powered
on or when it is reset. POST checks the basic integrity of the critical hardware
components in the server module (CMP, memory, and I/O subsystem).
You can also run POST as system-level hardware diagnostic tool. To do this, use the
Oracle ILOM set command to set the parameter keyswitch_state to diag.
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
Affect POST Behavior" on page
If POST detects a faulty component, the component is disabled automatically. If the
system 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 system will boot and run
using the remaining cores.
