I need a little direction to help solve an IPoIB issue. Software: OFED 1.3 and 1.4 stacks, running OpenSM
Problem: IPoIB connections fail, meaning a node cannot ping all or some of the other IPoIB nodes. IB itself is still up, we can run IB tests with success. So far the only resolution is to restart the IB stack. Size of the cluster seems to be irrelevant. It has happened on clusters from around 64 to 1000s. My first instinct is that some information has been lost from SM/SA which is needed to create an IPoIB connection, but I'm not for sure what that information is or how to verify that it is gone. Thanks in advance, Todd
