Inadvertent System Error LED when redundancy error message logged in single power supply configuration - IBM Systemx
RETAIN tip: H207466
When Integrated Management Module (IMM) version 1.36 Build ID: YUOOF2A is running in a single node (standalone) system with only one power supply installed, indications and entries similar to the following example can be observed:
The system may be any of the following IBM servers:
Solution for SAP HANA Appliance, Type 7143, any model
This tip is not software specific.
This tip is not option specific.
The following system firmware level is affected:IMM Build ID: YUOOF2A
This behavior has been addressed and released beginning in IMM firmware version 1.38 Build ID: YUOOF2B.
The file is available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:
IBM recommends installing a second power supply to provide redundancy.
If the non-redundancy message is the only error event logged, then the symptoms can be ignored in a single power supply configuration.
This symptom is an inadvertent consequence of the changes made to the IMM version 1.36 firmware.
The fix does is to not illuminate the LEDs when only one power supply is installed.
By adding an additional power supply, the system avoids non-redundancy and does not illuminate the LEDs or log the error messages.
Note: When using the affected IMM version, there is no way to turn off manually the front or rear panel System Error LEDs.
