Lenovo ThinkServer TS200 Hardware Maintenance Manual for TS200 - Page 23

If possible, return the server to the condition it was in before the problem occurred. 2. Collect data. Thorough data collection is necessary for diagnosing hardware and software problems. a. Document error codes and system-board LEDs. • System error codes: See "POST error codes" on page 22 for information about a specific error code. • See "System-board LEDs" on page 133 for the location of the system-board LEDs. • Software or operating-system error codes: See the documentation for the software or operating system for information about a specific error code. See the manufacturer's Web site for documentation. b. Collect system data. Run the Dynamic System Analysis (DSA) diagnostics program to collect information about the hardware, firmware, software, and operating system. Have this information available when you contact Lenovo or an approved warranty service provider. See "Running the diagnostic programs" on page 67 for the instructions to run the DSA program. If you need to download the latest version of DSA, go to http://www.lenovo.com/support . 3. Follow the problem-resolution procedures. The four problem-resolution procedures are presented in the order in which they are most likely to solve your problem. Follow these procedures in the order in which they are presented: a. Check for and apply code updates. Most problems that appear to be caused by faulty hardware are actually caused by the server firmware (formerly BIOS firmware), device firmware, or device drivers that are not at the latest levels. 1) Determine the existing code levels. In DSA, click Firmware/VPD to view system firmware levels, or click Software to view operating-system levels. 2) Download and install updates of code that is not at the latest level. Important: Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code. To display a list of available updates for your server, go to http://www.lenovo.com/support . When you click an update, an information page is displayed, including a list of the problems that the update fixes. Review this list for your specific problem; however, even if your problem is not listed, installing the update might solve the problem. b. Check for and correct an incorrect configuration. If the server is incorrectly configured, a system function can fail to work when you enable it; if you make an incorrect change to the server configuration, a system function that has been enabled can stop working. 1) Make sure that all installed hardware and software are supported. See http://www.lenovo.com/support to verify that the server supports the installed operating system, optional devices, and software levels. If any hardware or software component is not supported, uninstall it to determine whether it is causing the problem. You must remove nonsupported hardware before you contact Lenovo or an approved warranty service provider for support. 2) Make sure that the server, operating system, and software are installed and configured correctly. Many configuration problems are caused by loose power or signal cables or incorrectly seated adapters. You might be able to solve the problem by turning off the server, reconnecting cables, Chapter 3. General Checkout 15
