Lenovo Dynamic System Analysis

Lenovo 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 Appendix C "DSA diagnostic test results" on page 829.
