POST
When you turn on the server, it performs a series of tests to check the operation of the server components
and some optional devices in the server. This series of tests is called the power-on self-test, or POST.
Note: This server does not use beep codes for server status.
If a power-on password is set, you must type the password and press Enter (when you are prompted),
for POST to run.
If POST detects a problem, an error message is displayed. See Appendix B “UEFI (POST) error codes” on
page 805 for more information.
If POST detects a problem, an error message is sent to the POST event log, see “Event logs” on page
58 for more information.
Lenovo Dynamic System Analysis
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) 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 829.
