6-62 Compaq ProLiant 8000 Servers Maintenance and Service Guide Table 6-16 ADU Diagnostic Messages continued Message Description System board is unable to identify which slots the controllers are in. Slot indicator on system board is not working correctly. Firmware recognizes both controllers as being installed in the same slot. The redundant controllers installed are not the same model. SOLUTION: Power down the system and verify that the redundant controllers are different models. If they are different models, replace the other controller with the same model as this one. This controller can't see the drives but the other controller can ADU detected two different controller models installed in a redundant controller configuration. This is not supported, and one or both controllers may not be operating properly. The other controller in the redundant controller configuration can recognize the drives, but this controller cannot. Recommended Action 1. Make sure both controllers are fully seated in their slots. If the problem persists, this might indicate a controller problem or a system board problem. 2. Remove one of the controllers in the configuration and see if the remaining controller generates a Power-On Self-Test (POST) message. 3. Move the remaining controller to the other slot to see if it still generates a POST message. 4. Repeat these steps with the other controller. If both controllers give POST messages in one slot but not the other, it is a system board problem. If one of the controllers gives POST messages and the other controller does not, replace the controller that is giving the POST messages. Contact a Compaq authorized service provider for any warranty replacements. Use the same controller models for redundant controller configurations. Resolve any other errors and then rerun ADU. continued
