This task provides instructions for troubleshooting DIMM errors when the problem persists after swapping the faulty DIMMs as described in How to Isolate and Replace Faulty DIMM Pairs.
Caution - Before handling components, attach an antistatic wrist strap to a chassis ground (any unpainted metal surface). The system’s printed circuit boards and hard drives contain components that are extremely sensitive to static electricity. |
Before You Begin
This task requires:
Assistance of Oracle service personnel
Access to Oracle ILOM
The ability to remove a CMOD from the server
For example, if the faulty pair is DIMM 0 and DIMM 4 on CPU 0:
If the error follows the DIMMs, replace them.
If the error remains in the same location, continue.
In other words, switch the positions of the two CPUs.
If the error continues to appear in the same DIMM slot, most likely there is an issue with the DIMM slot. Return the board to the Support Center for replacement.
If the error follows the CPU, replace the CPU and confirm that the memory error does not return.
