System memory information
The error correction code (ECC) memory controller chip set continuously monitors
the SIMM/DIMM memory in a server. When it detects an error (either single-bit
or multiple-bit), the System Management Interrupt (SMI) logs the error.
A service processor and the corresponding device driver must be installed on
the system.
Actions
Use the following actions to diagnose the SIMM/DIMM memory:
- View Unresolved Multi-bit Errors
When a multi-bit error occurs, the SMI handler logs the error to the system
error log, recognizes the DIMM as damaged in CMOS, and starts the server again.
During this start, the Light Path Diagnostic LED for the DIMM is illuminated,
and the DIMM is configured out of usable memory until you change the DIMM
and enable it through the setup utility. The Light Path Diagnostic LED status
checks to determine whether the DIMM is damaged.
- View Single-Bit Errors Threshold Events
Searches the error log to see if the single bit error threshold has been exceeded.
Single-bit errors occur more frequently and can be corrected by the chip set.
Results
The Results field displays the results of the action and provides detailed
information for resolving the problem. You might need to use the documentation
that comes with your server for information about correcting a failed device.
