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: The DVD-ROM drive 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
Considerations for Running Standalone Diagnostics from CD-ROM
Consider the following when you run standalone diagnostics:
v The diagnostic CD must remain in the DVD-ROM drive for the entire time that diagnostics are running.
v The diagnostic CD cannot be ejected from the DVD-ROM drive after the diagnostics have loaded. The
CD can only be ejected after the system has been turned off and then turned on (standalone mode) or
after the diagnostics program has terminated (online concurrent mode).
v The DVD-ROM drive from which diagnostics were loaded cannot be tested.
v The SCSI adapter (or circuitry) controlling the DVD-ROM drive from which diagnostics were loaded
cannot be tested.
Running the Standalone Diagnostics with CD-ROM
To load standalone diagnostics from the default boot list, perform the following procedure:
1. Verify with the system administrator and users that all programs may be stopped, then stop all
programs including the operating system.
2. Remove all tapes, diskettes, and CD-ROM discs.
3. Turn off the system.
Note: If AIX is running, type the shutdown command.
4. Wait until the Power-on LED stops flashing and remains off, then press the power button to turn on the
system.
5. Immediately insert the diagnostic CD-ROM into the DVD-ROM drive.
6. After the keyboard POST indicator displays on the firmware console and before the last POST
indicator (speaker) displays, press the numeric 5 key on either the directly attached keyboard or the
ASCII terminal to indicate that a service mode boot should be initiated using the default service mode
boot list.
7. Enter any requested passwords.
Note: If you are unable to load the diagnostics to the point when the DIAGNOSTIC OPERATING
INSTRUCTIONS display, call your support center for assistance.
Running Standalone Diagnostics from a Network Installation
Management (NIM) Server
A client system connected to a network with a Network Installation Management (NIM) server can boot
standalone diagnostics from the NIM server if the client-specific settings on both the NIM server and client
are correct.
