Details
The Message ID: SUN4V-8000-DX indicates diagnosis has determined that a
memory DIMM is faulty as a result of exceeding the threshold for correctable
memory errors. Memory pages associated with the correctable errors have been
retired and no data has been lost. However, the system is at increased risk
of incurring an uncorrectable error, which will cause a service
interruption, until the memory DIMM module is replaced.
Use the command fmdump -v -u EVENT_ID with the EVENT_ID from the console
message to locate the faulty DIMM. For example:
fmdump -v -u f92e9fbe-735e-c218-cf87-9e1720a28004
