TABLE E-1 Event Descriptions and Recommended Actions (Continued) Event Code 127 136 139 140 141 152 153 Event Type Description Recommended Action Warning The controller has detected an invalid disk drive dual-port connection. This connection does not have the benefit of fault tolerance. Failure of the disk drive port would cause loss of access to the drive. The single disk drive port should be connected to one controller only. Warning Errors detected on the specified disk channel have caused the storage system to mark the channel as degraded. Determine the source of the errors on the specified disk channel and replace the faulty hardware. When the problem is fixed, event 189 is logged. Informational The Management Controller has powered up or restarted. Informational The Management Controller is about to restart. Informational The IP address has been changed in the Management Controller. Informational or warning The Management Controller (MC) has not sent a command to the Storage Controller (SC) for an interval that exceeds the MC communication timeout, and may have failed. This is sometimes referred to as a "LAN not talking" error. This event is logged as informational when the SC has not received communication from the MC for 160 seconds. If communication is restored in less than 15 minutes, event 153 is logged. If the SC has not received communication from the MC for 15 minutes, this event is logged as a warning, the SC restarts the MC, and event 156 is logged. If this occurs repeatedly and user interfaces are not working normally, a hardware failure is indicated. Replace the controller module that is logging this event. Informational The Management Controller has reestablished communication with the Storage Controller. Appendix E Event Codes 285
