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 ªRunning System Verification When Connected to an HMCº on page 154.
Step 1. Considerations Before Running This Procedure
Read the following before using this procedure:
vThe AIX operating system must be installed on your system before you attempt to perform this procedure.
vIf this system unit is directly attached to another system unit or attached to a network, be sure communication with the other systems is stopped.
vThis procedure requires use of all of the system resources. No other activity can be running on the system while you are performing this procedure.
vThis 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.
vThis 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.
vIf 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.
vIf your system is connected to an HMC, refer to ªStep 1. Running Online Diagnostics in Service Modeº on page 154.
