Lenovo Dynamic System Analysis Preboot diagnostic program

Lenovo Dynamic System Analysis (DSA) Preboot diagnostic program collects and analyzes system information to aid in diagnosing compute node problems.

DSA Preboot performs the following tasks:
  • Collects system information into a compressed XML file that you can send to Support
  • Provides a bootable image that you can use to run extended hardware tests independent of the operating system or applications
  • Collects the version and license information from local VMware ESXi hypervisor software

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

To obtain DSA code and the Dynamic System Analysis Installation and User's Guide, go to the Lenovo Dynamic System Analysis (DSA) website.

To diagnose and resolve DSA messages, see DSA diagnostic test results.
