Dynamic System Analysis

Dynamic System Analysis (DSA) collects and analyzes system information to aid in diagnosing server
problems. Lenovo provides DSA Preboot edition to users.
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
• Light path diagnostics status
• Network interfaces and settings
• Performance data and details about processes that are running
• RAID controller configuration
• Service processor (IMM2) 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 1151.
If you cannot find a problem by using DSA, see "Solving undetermined problems" on page 106 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 codes and the Dynamic

DSA Preboot
This topic introduces DSA Preboot.
DSA Preboot runs outside of the operating system; you must restart the server to run it. It is provided in
the flash memory on the server, or you can create a bootable media such as a CD, DVD, ISO, USB, or
PXE using the ToolsCenter Bootable Media Creator (BoMC). For more details, see the BoMC User Guide
at https://support.lenovo.com/ us/en/documents/LNVO-BOMC. In addition to the capabilities of the other
editions of DSA, DSA Preboot includes diagnostic routines that would be disruptive to run within the
operating-system environment (such as resetting devices and causing loss of network connectivity). It has a
graphical user interface that you can use to specify which diagnostics to run and to view the diagnostic and
data collection results.
DSA Preboot provides diagnostics for the following system components, if they are installed:
• Emulex network adapter
• Optical devices (CD or DVD)
• Memory
• Microprocessor
