I looked at the arp table and the ib0 device is not listed. The state is 
marked as ACTIVE for port 1. Does this mean that a connection to opensm 
has been established and not necessarily that this interface has been 
enabled for use (meaning the connection to opensm with over eth0 instead 
of ib0)?
