Description
Action
3) Enable the DIMM connector for the DIMM that was replaced.
After installing a DIMM as a result of a DIMM failure, you might need to re-
enable the DIMM connector (slot) for the DIMM that you replaced. To
determine whether you need to re-enable the DIMM:
1. Verify that the amount of memory installed in the IBM MAX5 is the
expected amount of memory. You can verify the amount of memory that
is installed through the operating system, by watching the monitor as the
blade server starts up, or through the advanced management module
web interface.For more information about the advanced management
module web interface, see the http://www.ibm.com/systems/ support/
supportsite.wss/docdisplay? brandind=5000008&lndocid=MIGR-
5073887.
2. Run the Setup Utility to re-enable the DIMMs (see “Using the Setup
utility” on page 20 for more information).
IBM Dynamic System Analysis
IBM 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, include 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
• RAID and controller configuration
• Service processor (integrated management module) status and configuration
• System configuration
• Vital product data and firmware information
If you cannot find a problem by using DSA, see “Solving undetermined problems” on page 274.
Note:
DSA Preboot might appear to be unresponsive when you start the program. This is normal operation
while the program loads.
