Symptoms


The EoIB VNIC interfaces (eth8 & eth9) do not automatically re-link and re-join the bondeth0 client network interface when the InfiniBand (IB) link comes up, after an outage of that IB VNIC.  The IB interfaces and bondib0 do come back up.  This can result in an outage if an IB port or gateway leaf switch goes down as the bondeth0 is not fully intact.  Therefore if the second gateway leaf switch goes down at a later time, the bondeth0 will be down and the BDA nodes inaccessible via the client data network.
