Make sure that you entered the correct serial number (S/N) of the
secondary system and the correct path parameters (for example,
primary system port, secondary system port, and controller ID).
Make sure that the topology settings of the primary and secondary

Make sure that network relay devices (cables, connectors, switches,
ESCDs, extender devices, communication lines, and all other devices
connected to the extenders) are properly configured and functional.
Delete the failed path. You may need to change the minimum paths
setting or delete the secondary system in order to delete the path.
After deletion finishes, add the path or secondary system. by using
the Add Path dialog box or the Add DKC dialog box.
