on that memory channel. If either of these conditions is found, correct and retry with the same
DIMM. (Note: Event Log may contain a recent 00580A4 event denoting detected change in
DIMM population that could be related to this problem.)
2. Check IBM support site for an applicable firmware update that applies to this memory error. The
release notes will list the known problems the update addresses.
3. If the previous steps do not resolve the problem, at the next maintenance opportunity, replace

4. If PFA re-occurs on the same DIMM connector, swap the other DIMMs on the same memory
channel one at a time to a different memory channel or Processor. (check service information for
this product/Install guide for population requirements for sparing/paring modes). If PFA follows a
moved DIMM to any DIMM connector on the different memory channel, replace the moved DIMM.
