POST Overview

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.

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. Refer to the section

on setting the SPARC host keyswitch state in the 

Oracle ILOM Administrator’s Guide for

Configuration and Maintenance Firmware Release 4.0.x

 for a list of parameters and values.

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.

Configure POST

1.

Log in to Oracle ILOM.

See 

“Log In to Oracle ILOM (Service)” on page 28

.

2.

Set 

/HOST/diag

 to the value that corresponds to the POST configuration you want

to run.

This example sets the 

/HOST/diag

 

default_level

 to 

min

, which configures POST to run

according to other parameter values.

-> 

set /HOST/diag default_level=min

Set default_level to min
