Dynamic System Analysis

Dynamic System Analysis (DSA) collects and analyzes system information to aid in diagnosing server problems.

DSA collects the following information about the server:
  • Drive health information
  • Event logs for ServeRAID controllers and service processors
  • Hardware inventory, including PCI and USB information
  • Installed applications and hot fixes (available in DSA Portable only)
  • Kernel modules (available in DSA Portable only)
  • Light path diagnostics status
  • Network interfaces and settings
  • Performance data and details about processes that are running
  • RAID controller configuration
  • Service processor (integrated management module) status and configuration
  • System configuration
  • Vital product data and firmware information

For system-specific information about the action that you should take as a result of a message that DSA generates, see DSA diagnostic test results.

If you cannot find a problem by using DSA, see Solving undetermined problems for information about testing the server.

Note
DSA Preboot might appear to be unresponsive when you start the program. This is normal operation while the program loads.

Make sure that the server has the latest version of the DSA code. To obtain DSA code and the Dynamic System Analysis Installation and User's Guide, go to the Lenovo Dynamic System Analysis (DSA) website.

  • DSA editions
    Two editions of Dynamic System Analysis are available.
  • Running the DSA Preboot diagnostic programs
    Use this information to run the DSA Preboot diagnostic programs.
  • Diagnostic text messages
    Diagnostic text messages are displayed while the tests are running.
  • Viewing the test log results and transferring the DSA collection
    To view the test log for the results when the tests are completed, click the Success link in the Status column, if you are running the DSA graphical user interface, or type :x to exit the Execute Tests menu, if you are running the DSA interactive menu, or select Diagnostic Event Log in the graphical user interface. To transfer DSA Preboot collections to an external USB device, type the copy command in the DSA interactive menu.
