ABSTRACT:
A storage system and a path management method, which can facilitate node replacement are proposed. In the storage system, the host sets plural paths between the host and the volume and holds path information composed of management information on each of the paths. The management apparatus includes an integrated path management unit that collects the path information on each of the paths defined between the host and the volume from the corresponding host to manage all the collected information as integrated path information; retrieves an alternate path going through a node other than a specified node but has the same function as the specified node, for the path going through the specified node, based on the integrated path information; and displays results of the retrieval.
