This task creates a snapshot of the CE log, then uses the snapshot to locate memory errors.
BIOS updates the CE log every five minutes. After changing something, you must wait five minutes to ensure that the data in the CE log reflects the results of that change.
Use the Oracle ILOM web interface or the CLI to create a snapshot, as described in Creating a Data Collector Snapshot.
The data set should be normal. If you are using the web interface, do not select any of the check boxes.
The unzip action produces a directory ilom.
For example, you can search it for the string Uncorrectable.
It should contain lines similar to the following:
Mon May 8 02:54:12 2000 ID ffff V ECC No-UE CE Node 2 Branch 0 DIMM Pair(s): D0/D4 Mon May 8 02:54:12 2000 ID ffff : 12 00 02 00 02 00 03 00 00 00 00 00 00 00 00 00 16 | 00 00 00 00 00
The following table shows the mapping of nodes to CMODs and CPUs. In the physical system, CMOD 0 is on the bottom, and CMOD 3 is on the top.
The preceding example identifies the faulty DIMM pair as DIMMs 0,3 in CPU 0 of CMOD 2.
