When platform is updated from 3.0.3 to 3.0.4, then one of the addtional server's management console was eth1, hence although the server was enabled its IP address was not visible in server manager tab . One more thing is that volumes were not starting. I created some 4-5 volumes, but none of them started. Am not sure whether non-starting volume is related to eth1 being the management console or not. But the volumes created excluding the eth1 additional servers also did not start.
