Dynamic System Analysis - Lenovo x3300 M4 7382 Installation And Service Manual

Dynamic System Analysis

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 and 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 "Diagnostic text messages" on page 131.
If you cannot find a problem by using DSA, see "Solving undetermined problems" on page 154 for
information about testing the server.
Notes:
1. In a multi-node environment, each server has a unique DSA interface. You can view server-specific
information, such as event logs, from these unique DSA interfaces.
2. 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 code and the Dynamic
System Analysis Installation and User's Guide, go to
DSA editions
Two editions of Dynamic System Analysis are available.
• DSA Portable
DSA Portable Edition runs within the operating system; you do not have to restart the server to run it. It is
packaged as a self-extracting file that you download from the Web. When you run the file, it self-extracts
to a temporary folder and performs comprehensive collection of hardware and operating-system
information. After it runs, it automatically deletes the temporary files and folder and leaves the results of
the data collection and diagnostics on the server.
If you are able to start the server, use DSA Portable.
• 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
