Chapter 10. Using the System Verification Procedure

The system verification procedure is used to check the system for correct operation.
This chapter contains information about pre-procedure considerations and running the
system verification.

Step 1. Considerations before Running This Procedure

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. Before starting this procedure,
you should stop all programs and the operating system.
If this system unit is directly attached to another system unit or attached to a network, be
sure communications with the other system unit is stopped. If needed, see Chapter 2 for
more information about multiple system attachments.
This procedure requires a console terminal attached to the S1 port.
This procedure runs the diagnostic programs in standalone mode from either your normal
IPL source or from removable media (if installed). If the diagnostic programs are installed
on disk or LAN, these procedures should be run from disk or LAN. (See the operator
manual for your type tty terminal to find the key sequences you need to respond to the
diagnostic programs.)
If you need more information about standalone mode, see "Diagnostic Modes of
Operation" on page 8-7.
If a console is not selected, the diagnostics stop with c31 in the operator panel display.
The instructions for selecting a console are displayed on any terminal attached to the S1
port. Follow the displayed instructions to select a console display.
This procedure assumes that the AutoService IPL is enabled. If this flag is disabled, then
the system will display the MIANTENANCE MENU when booting. Refer to Appendix B,
"Modifying Service Support Parameters", to determine how to verify and change this
flag's setting; or, when the MAINTENANCE MENU is displayed select System Boot,
then Boot From List, and continue.
Go to Step 2.
