[ovirt-users] Node losing management network address?

Hi! I had weird occurence in my two node ovirt cluster today (I have HE). I noticed that one node had ovirtmgmt network unsynchronized. I tried to resynchronize it. This led the node being rebooted by HP ILO. After reboot the node came up with DHCP address. Tried to change it back by fixing ifcfg-ovirtmgmt to original static address. It reverter back to DHCP if I tried the resync the network. I decided to remove HE from the node in order to remove the node in order to be able to add it back. After I started HE removal, address popped back to static address. I did upgrade which was pending on node and after reboot it came back with DHCP address again. After this I removed the node from the cluster, added it back and now it seems to work. I'm just wondering how I prevent this from happening again? How this unsync situation happens for instance and why it decides that DHCP is the way to go? -Juhani
