Verifying the Hardware Operation
Chapter 2. Verifying the Hardware Operation
The system verification procedure checks the system for correct hardware operation. Use
this procedure to verify that your system is set up correctly. 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
Read the following before using 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.
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
sequences you need in order to respond to the diagnostics.
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.
Step 2. Loading the Diagnostics
Note: If the system is in Standby mode (Power–On LED on the operator panel is slowly
blinking and the operator panel displays OK), skip the first three steps of this
procedure. If the system is running, and you do not want to shut it down, begin on
item 6.
1. Stop all application programs running on the operating system.
2. Stop the operating system by logging on as root user and typing shutdown.
3. Wait for the system to go into standby mode. The Power–On LED on the operator panel
starts to slowly blink, and the operator panel displays an OK message, indicating that the
system is in standby mode. See the figure of the operator panel on page 1-15 for
locations of operator panel components that are referred to in this procedure.
4. If you are loading the diagnostics and running them from an ASCII terminal, you might
need to change your terminal settings. Record the normal settings, and be sure the
terminal attributes are set to work with the diagnostics. If needed, see the documentation
for your terminal hardware for terminal attributes.
5. Turn on the system by pressing the Power On/Off button once.
6. After the AIX operating system loads, log in as root.
7. Type diag at the command prompt.
8. Follow the instructions that appear on the display to select a console.
