ABSTRACT:
The storage controlling apparatus has a function for setting each of a plurality of ports in a controller for the current controller or for the standby controller, so that one port is switched to the other in a controller in case an error occurs in a controller or in a port. When in a normal operation, both of the controllers can be operated so as to improve the performance of the apparatus.
