• W.50001: [W.50001] A DIMM has been disabled due to an error detected during POST.
[W.50001] A DIMM has been disabled due to an error detected during POST.
Severity: Warning
User Response:
Complete the following steps:
1. If the DIMM was disabled because of a memory fault, follow the procedure for that event.
2. If no memory fault is recorded in the logs and no DIMM connector error LEDs are lit, re-enable the
DIMM through the Setup utility or the Advanced Settings Utility (ASU).
3. If problem persists, Power cycle the node from management console.
4. Reset IMM to default settings.
5. Reset UEFI to default settings.
6. Reflash IMM and UEFI firmware.
7. (Trained service technician only) Replace system board.
• W.58001: [W.58001] The PFA Threshold limit (correctable error logging limit) has been exceeded on
DIMM number % at address %. MC5 Status contains % and MC5 Misc contains %.
[W.58001] The PFA Threshold limit (correctable error logging limit) has been exceeded on DIMM number
% at address %. MC5 Status contains % and MC5 Misc contains %.
Severity: Warning
User Response:
Complete the following steps:
1. If the node has recently been installed, moved, serviced, or upgraded, verify that the DIMM is
properly seated and visually verify that there is no foreign material in any DIMM connector 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 website 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 the
affected DIMM (as indicated by LightPath and/or failure log entry).
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.
5. Check IBM Support website for an applicable Service Bulletins (Service bulletins) that applies to this
memory error. (Link to IBM support service bulletins)
6. (Trained service technician only) If problem continues to re-occur on the same DIMM connector,
inspect DIMM connector for foreign material and remove, if found. If connector is damaged, replace
system board.
7. (Trained service technician only) Remove affected Processor and inspect Processor socket pins for
damaged or mis-aligned pins. If damage is found or Processor is an upgrade part, replace system
board.
8. (Trained service technician only) Replace affected processor.
9. (Trained service technician only) Replace system board.
