Service bulletinsIBM continually updates the support website with the latest tips and techniquesthat you can use to solve problem that you might have with the System x3650 M5server.To find service bulletins that are available for the IBM System x3650 M5 server, goto http://www.ibm.com/supportportal/ and search for 5462, and retain.Checkout procedureThe checkout procedure is the sequence of tasks that you should follow todiagnose a problem in the server.About the checkout procedureBefore you perform the checkout procedure for diagnosing hardware problems,review the following information.v Read the safety information that begins on page “Safety” on page vii.v IBM Dynamic System Analysis (DSA) provides the primary methods of testingthe major components of the server, such as the system board, Ethernetcontroller, keyboard, mouse (pointing device), serial ports, and hard disk drives.You can also use them to test some external devices. If you are not sure whethera problem is caused by the hardware or by the software, you can use thediagnostic programs to confirm that the hardware is working correctly.v When you run DSA, a single problem might cause more than one error message.When this happens, correct the cause of the first error message. The other errormessages usually will not occur the next time you run DSA.Exception: If multiple error codes or LCD system information display panelindicate a microprocessor error, the error might be in the microprocessor or inthe microprocessor socket. See “Microprocessor problems” on page 96 forinformation about diagnosing microprocessor problems.v Before you run DSA, you must determine whether the failing server is part of ashared hard disk drive cluster (two or more servers sharing external storagedevices). If it is part of a cluster, you can run all diagnostic programs except theones that test the storage unit (that is, a hard disk drive in the storage unit) orthe storage adapter that is attached to the storage unit. The failing server mightbe part of a cluster if any of the following conditions is true:– You have identified the failing server as part of a cluster (two or more serverssharing external storage devices).– One or more external storage units are attached to the failing server and atleast one of the attached storage units is also attached to another server orunidentifiable device.– One or more servers are located near the failing server.Important: If the server is part of a shared hard disk drive cluster, run one testat a time. Do not run any suite of tests, such as “quick” or “normal” tests,because this might enable the hard disk drive diagnostic tests.v If the server is halted and a POST error code is displayed, see Appendix B,“UEFI/POST diagnostic codes,” on page 817. If the server is halted and no errormessage is displayed, see “Troubleshooting by symptom” on page 88 and“Solving undetermined problems” on page 115.74 System x3650 M5 Type 5462: Installation and Service Guide
