Chapter 3. Using the Standalone and Online
Diagnostics
Sources for the Diagnostic Programs
The diagnostics consist of Standalone Diagnostics and Online Diagnostics. Standalone
Diagnostics are resident on removable media. They must be booted before they can be run.
If booted, they have no access to the AIX Error Log or the AIX Configuration Data.
Online Diagnostics, when installed, are resident with AIX on the disk or server. They can be
booted in single user mode (referred to as service mode), run in maintenance mode
(referred to as maintenance mode), or run concurrently (referred to as concurrent mode)
with other applications. They have access to the AIX Error Log and the AIX Configuration
Data.
Standalone and Online Diagnostics Operating Considerations
Consider the following before using the diagnostic programs:
The following devices are not supported on Version 4.1 and higher of diagnostics:
– 8–bit and 24–bit 3D color graphics adapter (FFC 876 and 879)
– M–Video Capture adapter (FFC 985)
– M–Video Capture and Playback adapter (FFC 977)
– Async expansion adapter and drawer (FFC 867 and 288)
– T1/J1 Portmaster Adapter/A (FFC 851)
– E1 Portmaster Adapter/A (FFC C18)
Support for the following adapters has been withdrawn beginning with AIX version 4.3.
– POWER GtO Grahpics Adapter (FFC B50, B51, B52, B53, C12, C13, C14)
– POWER Gt1 Graphics Adapter (FFC 880, B34, B35, B42)
– POWER Gt1x Graphics Adapter (FFC 880, B34, B35, B42)
– Network Terminal Accelerator Adapter,256 (FFC 838)
– Network Terminal Accelerator Adapter,2048 (FFC 838)
Some supplemental diagnostic diskettes are incompatible with version 4.1 or later
diagnostics and will not work when used with version 4.1 CD–ROM or tape based
diagnostics.
To test these devices use an earlier version of either the diskette diagnostics or the
CD–ROM based diagnostics.
Run Online Diagnostics in Service Mode when possible, unless otherwise directed. The
Online Diagnostics perform additional functions, compared to Standalone Diagnostics.
This ensures that the error state of the system is captured in NVRAM for your use in
fixing the problem. The AIX error log and SMIT are only available when diagnostics are
run from the disk drive.
When running Online Diagnostics, device support for some devices may not have been
installed. If this is the case, that device will not appear in the resource list.
When running Standalone Diagnostics, device support for some devices may be
contained on supplemental diagnostic media. If this is the case, the device will not appear
in the resource list when running diagnostics unless the supplemental media has been
processed.
