Hi The issue with IPoIB address change is not just LID change but also QP change. (IPoIB define the MAC to be QP,GID) .
Anytime you do ifconfig down/up you might get a new QP and thus you need to refresh the ARP... I second Mike K. and propose we use gratuitous ARP reply whenever an IPoIB interface is brought up. > I wonder if this is why when I reload the IB drivers on one node > I sometimes have to reload them on other nodes too.
