Lenovo Dynamic System Analysis

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

DSA collects the following information about the compute node:
  • Drive health information for drives that are not part of RAID arrays.
  • Event logs for ServeRAID controllers and system-management processors
  • Hardware inventory, including PCI and USB information
  • Installed applications and hot fixes
  • Kernel modules
  • Light path diagnostics status
  • Network interfaces and settings
  • Performance data and details about processes that are running
  • Integrated management module 2 status and configuration
  • System configuration
  • Vital product data and firmware information

DSA creates a DSA log, which is a chronologically ordered merge of the system-event log (as the IPMI event log), the IMM event log (as the ASM event log), and the operating-system event logs. You can send the DSA log as a file to a support representative or view the information as a text file or HTML file.

In a multi-node environment, each node has a unique DSA interface. You can view node-specific information, such as error logs, from these unique DSA interfaces.
