[ovirt-users] Upgrade host to 4.2 - 10gbe connection does not work anymore

Hi All, I did successfully upgraded my 4.1 hosted engine and the first node to 4.2.3. Since upgrade, the node's 10Gbe connection does not work. It was the connection between host and storage. That is why, now I can't activate my node. I have IP and I have all of bonding, and it seems to fine. All other networks and bonds (1gbe) is working fine, I can communicate with other hosts. I had a mode-1 (active/passive) bonding on that interfaces. I can ping from other nodes, but not from this. Also, I did a full OS upgrade (yum update) on node. Somebody could me help? Thanks in advance, R Tibor
