Running POST
Power on self test (POST) is a group of PROM-based tests that run when the server
is powered on or reset. POST checks the basic integrity of the critical hardware
components in the server (motherboard, memory, and I/O buses).
If POST detects a faulty component, it is disabled automatically. If the system is
capable of running without the disabled component, the system will boot when
POST is complete. For example, if one of the processor cores is deemed faulty by
POST, the core will be disabled, and the system will boot and run using the
remaining cores.
Devices can be manually enabled or disabled using ASR commands (see “Managing
System Components with Automatic System Recovery Commands” on page 40).
Controlling How POST Runs
The server can be configured for normal, extensive, or no POST execution. You can
also control the level of tests that run, the amount of POST output that is displayed,
and which reset events trigger POST by using ALOM variables.
