boot list. (The default boot list contains five entries, and for each matching device
type found in the system unit, the system makes an entry in the service mode boot
list.)
v The service mode boot list can be modified using the system diagnostics "Display or
Change Bootlist" service aid. It cannot be modified under the System Management
Services.
v If no service mode boot list is present, the system uses the default boot list.
Online and Standalone Diagnostics Operating Considerations
Note: When possible, run online diagnostics in service mode. Online diagnostics
Consider the following items before using the diagnostics:
v Standalone diagnostics can run on systems configured for either a full (or single)
system partition or a (multiple) partitioned system. When running in a partitioned
system, the device from which you are booting standalone diagnostics must be made
available to the partition dedicated to running standalone diagnostics. This may
require moving the device from the partition that currently contains the boot device
(for example, the CD-ROM or network adapter connected to the NIM server that has
a standalone diagnostic image) to the partition used to run standalone diagnostics. If
you move devices, reboot both partitions. For more information, see "Standalone
Diagnostic Operation" on page 277.
v When diagnostics are installed, the device support for some devices might not get
installed. If this is the case, that device does not display in the diagnostic test list
when running disk-based diagnostics.
v When running diagnostics in a partitioned system, diagnostics will work only with the
resources that were assigned to that partition. You must run diagnostics in the
partition containing the resource that you want to test.
Identifying the Terminal Type to the Diagnostics
When you run diagnostics, you must identify which type of terminal you are using. If the
terminal type is not known when the FUNCTION SELECTION menu is displayed, the
diagnostics do not allow you to continue until a terminal is selected from the DEFINE
TERMINAL option menu.
Undefined Terminal Types
If you specify an undefined terminal type from the DEFINE TERMINAL option menu, the
menu prompts the user to enter a valid terminal type. The menu redisplays until either a
valid type is entered or you exit the DEFINE TERMINAL option.

perform additional functions compared to standalone diagnostics. Running online
diagnostics in service mode ensures that the error state of the system that has
been captured in NVRAM is available for your use in analyzing the problem. The
AIX error log and certain SMIT functions are only available when diagnostics are
run from the disk drive.
