The Oracle ILOM show faulty command displays current faults, including DIMM failures.
If a DIMM is faulty, the show faulty output is similar to this example.
-> show faulty Target | Property | Value --------------------+-------------------+------------------- /SP/faultmgmt/0 | fru | /SYS/MB/CM/CMP/BOB21/CH0 /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/CM/CMP/BOB21/CH0 faults/0 | | Forced fail(POST)
In this example, /SYS/MB/CM/CMP/BOB21/CH0 indicates the DIMM slot on the motherboard that is farthest from the power supplies.
