ibtracert
The tool ibtracert determines the path that IB packets travel between two
nodes. It is installed from the openib-diag RPM. The IB LIDs of the two nodes
in this example are determined by using the ipath_control -i command on
each node. The ibtracert tool produces output similar to the following when
run (as a root user) from a node on the IB fabric:
# ibtracert 0xb9 0x9a
