Maintenance Analysis Procedures (MAPs)
Step 11
(from Step 10)
1. Follow the instructions on the display to select your console.
2. When the Diagnostics Operating Instructions display, press the Enter key.
3. If the terminal type has not been defined or you are IPLing from CD-ROM, you must use
the Initialize Terminal option on the FUNCTION SELECTION menu to initialize the AIX
operating system environment before you can continue with the diagnostics. This is a
separate and different operation than selecting the console display.
4. Select Advanced Diagnostics Routines.
5. When the DIAGNOSTIC MODE SELECTION menu displays, select System Verification.
6. Run the diagnostics for each of the adapters and devices on the test list.
Did you get an SRN?
NO One of the adapters or devices you removed is causing the problem. Install
the adapters and devices one at a time to determine the failing adapter or
device. Test the system after each adapter or device is installed. Go to
“Map 0410: Repair Checkout” in the
Diagnostic Information For Micro
Channel Bus Systems.
YES Go to Step 12.
Step 12
(from Step 11)
Look at the FRU part numbers associated with the SRN.
Have you exchanged all the FRUs that correspond to the failing function codes?
NO Exchange the FRU with the highest failure percentage that has not been
changed.
Repeat Step 12 until all the FRUs associated with the SRN have been
replaced or the diagnostics run with no trouble found. Run the diagnostics
after each FRU is exchanged.
If the diagnostics run without error, go to “Map 0410: Repair Checkout” in
the
Diagnostic Information For Micro Channel Bus Systems.
YES One of the FRUs remaining in the system unit is defective.
In the following order, exchange the FRUs that have not been exchanged:
1. System planar (SP)
Test the FRU by running the failing test.
If the symptom did not change and all the FRUs have been exchanged call
your service support person for assistance.
If the symptom has changed check for loose cards, cables, and obvious
problems. If you do not find a problem return to Step 1 in this MAP and
follow the instructions for the new symptom.
