TABLE E-1 Event Descriptions and Recommended Actions (Continued) Event Code 163 166 167 Event Type Warning Warning Warning Description Recommended Action The host FC World Wide Names (node and port) previously presented by an offline controller module in this system are unknown. This event has two possible causes: • The online controller module reporting the event was replaced or moved while the system was powered off. • The online controller module had its flash configuration (where previously used WWNs are stored) cleared. The online controller module recovers from this situation by generating a WWN for the other controller module based on its own serial number. Verify the WWN information for the other controller module on all hosts that access it. The RAID metadata level of the two controllers does not match. Usually, the controller at the higher firmware level can read metadata written by a controller at a lower firmware level. The reverse is typically not true. Therefore, if the controller at the higher firmware level failed, the surviving controller at the lower firmware level cannot read the metadata on drives that have failed over. Update the controller with the lower firmware level to match the firmware level on the other controller. A diagnostic test at controller bootup detected an abnormal operation, which might require a power cycle to correct. A service technician must review the error information returned.
