Chapter 7. 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.
Running System Verification When Not Connected to an Hardware Management
Console (HMC)
If you running this procedure and are not connected to an HMC, perform the following.
If you are connected to an HMC, go to “Running System Verification When Connected
to an HMC” on page 154.
Step 1. Considerations Before Running This Procedure
Read the following before using this procedure:
v The AIX operating system must be installed on your system before you attempt to
perform this procedure.
v If this system unit is directly attached to another system unit or attached to a
network, be sure communication with the other systems is stopped.
v 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, an ASCII terminal
attached to the S1 port, or an HMC connected to an HMC port on the system.
v 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 sequences you need in order to respond to the diagnostics.
v If a console display is not selected, the diagnostics stop. The instructions for
selecting a console display are displayed on all of the graphic displays and any
terminal attached to the S1 port. Follow the displayed instructions to select a console
display.
v If your system is connected to an HMC, refer to “Step 1. Running Online Diagnostics
in Service Mode” on page 154.
