156 Warning The Management Controller (MC) has been restarted from the Storage Controller (SC) for the purpose of error recovery. Recommended actions • If this event occurs more than twice per hour, contact technical support. Informational The Management Controller (MC) has been restarted from the Storage Controller (SC) in a normal case, such as when initiated by a user. Recommended actions • No action required. 157 Error A failure occurred when trying to write to the Storage Controller (SC) flash chip. Recommended actions • Replace the controller module. 158 Informational A correctable ECC error occurred in the CPU memory. Recommended actions • No action required. 161 Informational One or more enclosures do not have a valid path to an enclosure management processor (EMP). All enclosure EMPs are disabled. Recommended actions • Contact technical support to resolve this configuration problem. 162 Warning The host WWNs (node and port) previously presented by this controller module are unknown. In a dual-controller system this event has two possible causes: • One or both controller modules have been replaced or moved while the system was powered off. • One or both controller modules have had their flash configuration cleared (this is where the previously used WWNs are stored). The controller module recovers from this situation by generating a WWN based on its own serial number. Recommended actions • If the controller was replaced or someone reprogrammed its FRU ID data, verify the WWN information for this controller module on all hosts that access it. 16
