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 and other resources that cannot be
tested by the online diagnostics.
Note: Error log analysis is not done by the standalone diagnostics. If running from the
diagnostic CD-ROM, the CD-ROM drive and the SCSI controller that controls it
cannot be tested by the standalone diagnostics.
Running the Standalone Diagnostics
To run standalone diagnostics in service mode, use the following steps:
1. Stop all programs including the AIX operating system (get help if needed).
2. Remove all tapes, diskettes, and compact discs.
3. Turn off the system unit power.
4. Turn on the system unit power.
5. Insert the diagnostic media.
6. When the keyboard POST indicator appears, press the 5 key on the directly
attached keyboard, or on the TTY keyboard.
7. Enter any requested passwords.
8. Follow any instructions to select the console.
9. After the diagnostic controller loads, DIAGNOSTIC OPERATING INSTRUCTIONS
appear on the console display.
10. Follow the displayed instructions to test the desired resources.
