Abstract:
Method and system for managing port failover in storage system comprising first storage processor and first port and second storage processor and second port. Storage system adapted to communicate with FC switch. Storage system providing first and second names characterizing first and second ports to switch for registration such that the first name associated with first port and second name associated with second port. Storage system detects the state of first and second processors. Failure state in first or second processor activates deregistration of port associated therewith. Storage system providing to switch for re-registration one of the names in response to detecting failure in processor associated with one of the ports. The one of the names provided to switch such that the one of the names characterizing the one of the ports is associated with the other of the ports.
