Problem

DSA Loopback Test Failure for the Onboard Ethernet NIC '516-901-000: A failure was detected during the loopback test'

Resolving The Problem

Source

RETAIN tip: H211881

Symptom

Network Interface Controller (NIC) PHY / MAC loopback test may intermittently fail when using preboot Dynamic System Analysis (DSA Preboot) environment. The Diagnostics Test will report the following error message:

 

516-901-000: A failure was detected during the loopback test at the physical layer 1. Check component firmware level and upgrade if necessary. The installed firmware level can be found in the DSA Dia...

The system may be any of the following IBM servers:

This tip is not software specific.

The system has the symptom described above.

Solution

This behavior will be corrected with an update to Emulex Common Information Model (CIM) Provider software which will be available with IBM System x Tool Center software pack.

The target date for this release is scheduled for Second Quarter 2014.

The file is or will be 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:

http://www.ibm.com/support/fixcentral/

Workaround

Restart the preboot DSA environment and execute DSA Preboot Diagnostics test for the on-board network interface controller (NIC).

Additional information

This intermittent diagnostics failure is not the result of any physical layer issue, and has no functional impact to the on-board Ethernet NIC ports for the system or its networking operations.
