W.3818005 [W.3818005] The CRTM flash driver could not successfully flash the staging area. The update was
aborted
Explanation: CRTM Update Aborted
Severity: Warning
User response: Complete the following steps:
1. Continue booting system. If system does not reset, manually reset the system.
2. If the error is not reported on the subsequent boot, no additional recovery action is required.
3. If the event persists, continue booting system and reflash UEFI image.
4. (Trained service technician only) Replace the system board.
W.3938002 [W.3938002] A boot configuration error has been detected.
Explanation: Boot Configuration Error
Severity: Warning
User response: Complete the following steps:
1. F1 Setup -> Save Settings
2. Retry OOB config update
W.50001 [W.50001] A DIMM has been disabled due to an error detected during POST.
Explanation: DIMM Disabled
Severity: Info
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 %.
Explanation: DIMM PFA Threshold Exceeded
Severity: Error
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 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 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.
