Chapter 7. Using the System Verification Procedure

Use the system verification procedure to check the system for correct operation.
If you are analyzing a hardware problem, see "Chapter 8. Hardware Problem
Determination" on page 119.

Step 1. Considerations before Running This Procedure

Notes:
1. If this system unit is directly attached to another system unit or attached to a
network, make sure that communications with the other system unit are stopped.
2. This procedure requires the use of all system resources. No other activity can be
running on the system while you are doing this procedure.
Read the following before using this procedure:
v This procedure requires a display connected to the video port or an American
National Standard Code for Information Interchange (ASCII) terminal attached to the
S1 port.
v Before starting this procedure, stop all programs and the operating system.
v This procedure runs the Online Diagnostics in Service mode or Standalone
Diagnostics. If the Online Diagnostics are installed, run them. See the operator
manual for your type of ASCII terminal to find the key sequences you need in order
to respond to the diagnostics.
v For additional information about diagnostics, see "Chapter 5. Using the Online and
Standalone Diagnostics" on page 73.
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 Go to "Step 2. Loading the Diagnostics".

Step 2. Loading the Diagnostics

1. Stop all application programs running on the operating system.
2. Stop the operating system.
3. Turn off the power.
4. If you are loading the Standalone Diagnostics and running them from an ASCII
terminal, do the following:
v The attributes for the terminal must be set to match the defaults of the
v If you need to change any settings, record the normal settings, and make sure
diagnostics.
that the terminal attributes are set to work with the diagnostics. If needed, see
"Running the Diagnostics from a TTY Terminal" on page 75.
