Online Diagnostics Modes of Operation
Note: Online diagnostics can only be run if AIX is installed.
The online diagnostics can be run in the following modes:
v Service Mode
v Concurrent Mode
v Maintenance Mode
Service Mode
Service mode provides the most complete checkout of the system resources. This mode also requires that
no other programs are running. Except for the SCSI adapter and the disk drives used for paging, all
resources on the system can be tested. However, note that the memory and processor are only tested
during POST, and the results of the POST tests are reported by diagnostics.
Error-log analysis is done in service mode when you select the Problem Determination option on the
DIAGNOSTIC MODE SELECTION menu.
Consider the following when you run the online diagnostics from a server or a disk:
v The diagnostics cannot be loaded and run from a disk until the AIX operating system has been installed
and configured.
v The diagnostics cannot be loaded on a system (client) from a server if that system is not set up to boot
from a server over a network. When the system is set up to boot from a server, the diagnostics are run
in the same manner as they are from disk.
v If the diagnostics are loaded from disk or a server, you must shut down the AIX operating system before
turning off the system unit to prevent possible damage to disk data. Do this in either of the following
ways:
– If the diagnostics were loaded in standalone mode, press the F3 key until DIAGNOSTIC OPERATING
INSTRUCTIONS displays. Then press the F3 key once again to shut down the AIX operating system.
– If the diagnostics were loaded in maintenance or concurrent mode, type the shutdown -F command.
v Under some conditions, the system might stop, with instructions displayed on attached displays and
terminals. Follow the instructions to select a console display.
Running the Online Diagnostics in Service Mode
Online diagnostics can be loaded by booting from a hard file in the custom boot list by pressing the
numeric 6 key on the keyboard.
To boot from the devices listed in the service mode 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.
Note: If AIX is running, type the shutdown command.
3. Wait until the Power-on LED stops flashing and remains off, then press the power button to turn the
system on.
4. When the keyboard indicator appears during startup, press the numeric 6 key on the keyboard.
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.
