Chapter 2. Verifying the Hardware Operation
The system verification procedure checks the system for correct hardware operation. If
you have a problem with your system in the future, use this procedure to test the
system hardware to help you determine if you have a hardware problem. Run the
system verification procedure as described in the following steps.
Step 1. Considerations Before Running This Procedure

The AIX operating system must be installed on your system before you attempt to
perform this procedure.

If this system unit is directly attached to another system unit or attached to a
network, be sure communications with the other systems are stopped.

This procedure requires use of all of the system resources. No other activity can be
running on the system while you are performing this procedure.
v
This procedure requires a display connected to a graphics adapter, or an ASCII
terminal attached to the S1 port or the S2 port.

This procedure runs the AIX online diagnostics in service mode. If the system
console is an ASCII terminal, see the documentation for your type of ASCII terminal
to find the key sequence you need in order to respond to the diagnostics.

You must select a console display before running the diagnostics. The instructions for
selecting a console display are displayed on all of the graphic displays or a terminal
attached to the S1 port or the S2 port. Follow the displayed instructions to select a
console display.
Step 2. Loading the Diagnostics

last POST indicator (speaker) displays, press the numeric 6 key on either the
directly attached keyboard or the ASCII terminal to indicate that a service mode
boot should be initiated using the customized service mode boot list.
