Error description

  • If using the SAN Communications driver to communicate between
cluster nodes, there is a chance that the driver will not
recover from an FC dynamic tracking event.  In this case, the
two nodes would no longer be able to communicate using
SANComm.  This only happens if the dynamic tracking even occurs
during a period of heavy message traffic over SANComm.
