Cause
As per the above ILOM outputs it is very clear that one of the DIMM is faulted.
In this case, it is the DIMM at P1/D5 persistently failing during MRC test and its neighbor DIMM at P1/D4 being disabled as a result.
But, it is possible that any of the DIMMs can fault/fail.
In this scenario, the cause of the fault is due to a damaged hardware.
Another possible cause:
This issue can be caused due to the dual diagnosis of memory correctable errors on a system that is running a Solaris OS. ILOM detects the errors as well as Solaris FMA. Solaris FMA has the ability to do page retirement but ILOM does not and therefore can only fault an entire DIMM if it's failure criteria is met. Please check Solaris FMA where available. If it is not available then we will have to rely on the ILOM diagnosis.
Solution
Review the Solaris FMA diagnosis instead of the ILOM diagnosis of DIMM replacement. On systems not running Solaris you must obviously go with the ILOM diagnosis. In either case steps must be followed to clear the errors. Please follow the below steps:
Login to the ILOM command line interface as 'root' and use the following commands to clear the fault.
Example:
-> set /SYS/MB/P0 clear_fault_action=true
Are you sure you want to clear /SYS/MB/P0 (y/n)? y
Set 'clear_fault_action' to 'true'
Now, if after clearing the errors, the issue reoccurs, then please replace the faulty DIMM through a field task generated through a Service Request (SR)
So, please open a Service Request for getting the faulty part replaced.
