Using the System Verification Procedure
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”.
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 use of all of the system resources. No other activity can be
running on the system while you are doing this procedure.
Read the following before using this procedure:
– This procedure requires a display connected to the video port or an ASCII terminal
attached to the S1 port.
– Before starting this procedure, stop all programs and the operating system.
– This procedure runs the Online Diagnostics in Service mode or Standalone
Diagnostics. If the Online Diagnostics are installed, they should be run. See the
operator manual for your type of ASCII terminal to find the key sequences you need in
order to respond to the diagnostics.
– For additional information about diagnostics, see Chapter 5, ”Using the Online and
Standalone 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.
– Go to Step 2.
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:
– The attributes for the terminal must be set to match the defaults of the diagnostics.
– If you need to change any settings, record the normal settings, and make sure the
terminal attributes are set to work with the diagnostics. If needed, see ”Running the
Diagnostics from a TTY Terminal” on page 5-3.
– Return to substep 5 when you finish checking the attributes.
5. Turn on the power.
a. When the keyboard indicator displays, press the numeric 5 key on the keyboard to
load the Standalone Diagnostics or the numeric 6 key on the keyboard to load the
Online Diagnostics.
