This is a helpful information. Yes at the moment I cannot vmkping from the host the 192.168.131 network. What is weird if I delete the vSwitch for the 192.168.130 network and do a HBA rescan. The HBA sees the connected targets for the 192.168..131 and there is traffic on both ports, which I cannot ping right now.
Yes I believe too, there is something wrong with the network. I haven't found the problem yet.
Thanks,
Edy
