POST

When you turn on the server, it performs a series of tests to check the operation of the server components

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
Action
In a Web browser, type the IP address for the IMM2 and go to the Event Log
page. For more information, see "Obtaining the IMM host name" on page 57
and "Logging in to the Web interface" on page 58.
