IBM Electronic Service AgentIBM Electronic Service Agent monitors, tracks, and captures system hardwareerrors and hardware and software inventory information, and reports serviceableproblems directly to IBM Support.You can also choose to collect data manually. It uses minimal system resources,and can be downloaded from the IBM website. For more information and todownload IBM Electronic Service Agent, go to http://www-01.ibm.com/support/esa/.Error messagesThis section provides the list of error codes and messages for UEFI/POST, IMM,and DSA that are generated when a problem is detected.See Appendix B, “UEFI/POST diagnostic codes,” on page 673, Appendix A,“Integrated management module II (IMM2) error messages,” on page 335, andAppendix C, “DSA diagnostic test results,” on page 693 for more information.Troubleshooting by symptomUse the troubleshooting tables to find solutions to problems that have identifiablesymptoms.About this taskIf you cannot find a solution to the problem in these tables, see Appendix C, “DSAdiagnostic test results,” on page 693 for information about testing the server and“Running the DSA Preboot diagnostic programs” on page 151 for additionalinformation about running DSA Preboot program. For additional information tohelp you solve problems, see “Start here” on page 127.If you have just added new software or a new optional device and the server isnot working, complete the following steps before you use the troubleshootingtables:Procedure1. Check the system-error LED on the operator information panel; if it is lit, checkthe light path diagnostics LEDs (see “Light path diagnostics” on page 134).2. Remove the software or device that you just added.3. Run IBM Dynamic System Analysis (DSA) to determine whether the server isrunning correctly (for information about using DSA, see Appendix C, “DSAdiagnostic test results,” on page 693).4. Reinstall the new software or new device.ResultsChapter 4. Troubleshooting 153
