Symptoms
PCIEX-8000-J5 and/or PCIEX-8000-KP FMA faults similar to those shown below will be reported. Systems utilizing InfiniBand fabric, i.e., T5-8 SSC are seen to be more susceptible to these faults.
The fmdump -e output will contain ereport.io.pciex.dl.btlp and/or ereport.io.pciex.dl.bdllp events. Examples are below the FMA examples.
