5. When DIAGNOSTIC OPERATING INSTRUCTIONS screen displays, follow the
displayed instructions to check out the desired resources.
6. When testing is complete, use the F3 key to return to DIAGNOSTIC OPERATING
INSTRUCTIONS. Press the F3 key again to return to the AIX operating system
prompt.
7. Press Ctrl-D to log off from root user or CE Login.
Standalone Diagnostic Operation
Use standalone diagnostics to test the system when the online diagnostics are not
installed and as a method of testing the disk drives that cannot be tested by the online
diagnostics.
Note: No error log analysis is done by the standalone diagnostics. The CD-ROM drive
Performing Slow Boot
To fully analyze all of the available information, perform the following steps before doing
a hardware repair or replacement:
1. Record the 8-character error code (and location code if present) in the operator
panel or that was reported by the customer.
2. Do a slow-mode boot in service mode. This boot can be specified using the System
Power Control Menu on the service processor main menu. (A fast-mode boot skips
much of the built-in diagnostic testing.) A slow-mode boot may yield a new
8-character error code on the operator panel and new errors in the service
processor error log. If a new error code is reported, use this code to continue
problem analysis.
Partitioned System Considerations for Standalone Diagnostics
To run standalone diagnostics on a full system partition, you must reboot the whole
system. However, for a partition in a partitioned system, you can boot standalone
diagnostics either in a given partition or on the entire system (which is the same
procedure as a full system partition). For a partitioned system, before running
standalone diagnostics on a given partition, the user must move the device from the
existing location where standalone diagnostics is booted (the CD-ROM drive or the
network adapter connected to the NIM server, in the case of NIM boot of standalone
and the SCSI controller that controls it cannot be tested by the standalone
diagnostics. Standalone diagnostics:
v Are resident on CD-ROM or a Network Installation Management (NIM) server
v Provide a method to test the system when the online diagnostics are not
installed or cannot be loaded from the disk drive
v Allow testing of the disk drives and other resources that cannot be tested by
the online diagnostics
v Do not have access to the AIX configuration data
v Do not have access to the AIX error log
v Do not allow for running of error log analysis
