The Oracle ILOM show faulty command displays current faults, including DIMM failures.
The output will be similar to this example if a DIMM is faulty.
-> show faulty Target | Property | Value --------------------+-------------------+------------------- /SP/faultmgmt/0 | fru | /SYS/MB/CMP0/MCU1/CH0/D0 /SP/faultmgmt/0 | timestamp | Dec 21 16:40:56 /SP/faultmgmt/0/ | timestamp | Dec 21 16:40:56 faults/0 /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU1/CH0/D0 faults/0 | | Forced fail(POST)
See DIMM FRU Names.
In this example, /SYS/MB/CMP0/MCU1/CH0/D0 indicates the DIMM slot on the mother board that is farthest from the power supplies.
