Chapter 4. Loading the System Diagnostics
The system diagnostics can be booted either from the default boot list or from the
service mode boot list. (The service mode boot list can be modified using the
system diagnostics "Display or Change Bootlist" service aid. The service mode boot
list cannot be modified under the System Management Services.)
To load Standalone Diagnostics from the default boot list, perform the following
procedure:
1. Verify with the system administrator and users that all programs may be stopped,
then do so.
2. Turn off the system.
3. Wait 30 seconds, and turn on the system.
4. Immediately insert the diagnostic CD-ROM into the CD-ROM drive.
5. When or after the keyboard indicator appears during startup, press the F5 key on
a directly-attached keyboard (or the number 5 key on an ASCII terminal).
6. Enter any requested passwords.
Online Diagnostics can be loaded by booting from the service mode boot list by
pressing the F6 key (on a directly-attached keyboard) or the number 6 key on an
ASCII terminal.
The procedure for booting from the devices listed in the service mode boot list
(Online Diagnostics) is the following:
1. Verify with the system administrator and users that all programs may be stopped,
then do so.
2. Turn off the system.
3. Wait 30 seconds, and turn on the system.
4. When or after the keyboard indicator appears during startup, press the F6 key on
a directly-attached keyboard (or the number 6 key on an ASCII terminal).
5. Enter any requested passwords.
After any requested passwords have been entered, the system attempts to boot from
the first device of each type found on the list. If no bootable image is found on the
first device of each type on the list, the system does not search through the other
devices of that type for a bootable image; instead, it polls the first device of the next
type.
