Diagnostic programs, messages, and error codesThe diagnostic programs are the primary method of testing the major componentsof the server. As you run the diagnostic programs, text messages are displayed onthe screen and are saved in the test log. A diagnostic text message indicates that aproblem has been detected and provides the action you should take as a result ofthe text message.Make sure that the server has the latest version of the diagnostic programs. Todownload the latest version, complete the following steps.Note: Changes are made periodically to the IBM Web site. The actual proceduremight vary slightly from what is described in this document.1. Go to http://www.ibm.com/systems/support/.2. Under Product support, click System x.3. Under Popular links, click Software and device drivers.4. Click IBM System x3650 M3 to display the matrix of downloadable files for theserver.Utilities are available to reset and update the code on the integrated USB flashdevice, if the diagnostic partition becomes damaged and does not start thediagnostic programs. For more information and to download the utilities, go tohttp://www.ibm.com/jct01004c/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5072294&brandind=5000008.Running the diagnostic programsTo run the diagnostic programs, complete the following steps:1. If the server is running, turn off the server and all attached devices.2. Turn on all attached devices; then, turn on the server.3. When the prompt Press F2 for Dynamic System Analysis (DSA) is displayed,press F2.Note: The DSA Preboot diagnostic program might appear to be unresponsivefor an unusual length of time when you start the program. This is normaloperation while the program loads. The loading process may take up to 10minutes.4. Optionally, select Quit to DSA to exit from the stand-alone memory diagnosticprogram.Note: After you exit from the stand-alone memory diagnostic environment, youmust restart the server to access the stand-alone memory diagnosticenvironment again.5. Type gui to display the graphical user interface, or select cmd to display theDSA interactive menu.6. Follow the instructions on the screen to select the diagnostic test to run.If the diagnostic programs do not detect any hardware errors but the problemremains during normal server operations, a software error might be the cause. Ifyou suspect a software problem, see the information that comes with your software.A single problem might cause more than one error message. When this happens,correct the cause of the first error message. The other error messages usually willnot occur the next time you run the diagnostic programs.72 IBM System x3650 M3 Types 4255, 7945, and 7949: Problem Determination and Service Guide
