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 2.1 (IMM2.1)) 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 IBM Dynamic System Analysis (DSA) website.
