Use this information to diagnose and resolve POST/UEFI error for the blade server.
UEFI/POST diagnostic error codes can be generated when the server starts up or while the server is running. UEFI/POST codes are logged in the IMM event log in the server.
For each event code, the following fields are displayed:
Event identifier
An identifier that uniquely identifies an event.
Event description
The logged message string that appears for an event.
Explanation
Additional information to explain why the event occurred.
Severity
An indication of the level of concern for the condition. The following severities can be displayed:
Table 1. Event severity levels.
Severity
Description
Informational
An informational message is something that was recorded for audit purposes, usually a user action or a change of states that is normal behavior.
Warning
A warning is not as severe as an error, but if possible, the condition should be corrected before it becomes an error. It might also be a condition that requires additional monitoring or maintenance.
Error
An error typically indicates a failure or critical condition that impairs service or an expected function.
User response
Indicate the actions that you should take to resolve the event.
Perform the steps listed in this section in the order shown until the problem is solved. After you perform all of the actions that are described in this field, if you cannot solve the problem, contact IBM support.
The following is the list of the UEFI/POST error codes and suggested actions to correct the detected problems.
Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
See Parts listing to determine which components are consumable, structural, or CRU parts.
If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained technician.

[W.50001] A DIMM has been disabled due to an error detected during POST.
DIMM Disabled.
If the memory module was disabled due to a memory fault, follow the procedure for that event and restart the server.
Check the IBM support website for an applicable retain tip or firmware update that applies to this memory event. If no memory fault is recorded in the logs and no DIMM connector error LED is lit, re-enable the memory modules using the Setup utility or the Advanced Settings Utility (ASU).
(Trained technician only) If the problem occurs on the same DIMM connector, check the DIMM connector. If the connector contains any foreign material or is damaged, replace the system-board assembly (see Removing the system-board assembly and Installing the system-board assembly).
(Trained technician only) Remove the affected microprocessor and check the microprocessor socket pins for any damaged pins. If a damage is found, replace the system-board assembly.
Make sure that there is at least one DIMM installed in the server.
If there are no memory faults recorded in the logs and no DIMM connector error LEDs are lit, make sure that all DIMM connectors are enabled by using the Setup utility or the Advance Settings Utility (ASU).
Reinstall all DIMMs in the correct population sequence (see Installing a memory module for more information).
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 %.
DIMM PFA Threshold Exceeded.
Refer to TIP H21455 for minimum code level.
Check the IBM support website for an applicable retain tip or firmware update that applies to this memory error.
Swap the affected DIMMs (as indicated by the error LEDs on the system board or the event logs) to a different memory channel or microprocessor (see Installing a memory module for memory population sequence).
If the error still occurs on the same DIMM, replace the affected DIMM.
Check the IBM support website for an applicable retain tip or firmware update that applies to this memory error.
Install the affected memory modules (as indicated by the error LEDs on the system board or the event logs) to a different memory channel or microprocessor (see Installing a memory module for memory population sequence).
