Note that you can test each node separately by making the source/destination
addresses the same. This may show that your first system, rc002, is working,
but rc003 is not.

It doesn't appear that the ibacm address information is correct. Having the
complete log file may help. The assigned address configuration would end up
being near the top of the log file.
ibacm uses an address file, ibacm_addr.cfg, to assign address information to
ports. If this file is not present, it will be created. It's a text file, and
the format is hopefully straightforward to follow. As a couple of places to
look , the file may be in:
/etc/rdma/ibacm_addr.cfg
/usr/local/etc/rdma/ibacm_addr.cfg
If you find the file, the simplest thing to do may be to just remove it. You
can look at the existing file to see that the correct IP address has been
assigned to the right port.
