IBM Dynamic System AnalysisThis topic provides an overview of the IBM Dynamic System Analysis program.IBM Dynamic System Analysis (DSA) collects and analyzes system information toaid in diagnosing server problems. DSA collects the following information aboutthe server:v Drive health informationv Event logs for ServeRAID controllers and service processorsv Hardware inventory, including PCI and USB informationv Installed applications and hot fixes (available in DSA Portable only)v Kernel modules (available in DSA Portable only)v Light path diagnostics statusv Network interfaces and settingsv Performance data and details about processes that are runningv RAID controller configurationv Service processor (integrated management module) status and configurationv System configurationv Vital product data and firmware informationAs you run Dynamic System Analysis, text messages are displayed on the screenand are saved in the DSA log. A diagnostic text message indicates that a problemhas been detected and provides the action you should take as a result of the textmessage.The following is a list of text results and messages that the diagnostic programsmight generate and suggested actions to correct the detected problems. Follow thesuggested actions in the order in which they are listed in the column.For system-specific information about the action that you should take as a result ofa message that DSA generates, see Appendix A, “DSA diagnostic test results,” onpage 301.If you cannot find a problem by using DSA, see “Solving undetermined problems”on page 199 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.
