ABSTRACT:
Proposed are a storage system, a path management method and a path management device capable of ensuring the processing performance demanded by a user while seeking to improve the access performance from a host system to a storage apparatus. Path switching control for dynamically switching the path to be used by the host system according to the loaded condition of the respective paths between the host system and the storage apparatus is executed; and a path is selected as needed according to a policy containing path switching rules created by a user, and path switching control for excluding the selected path from the target and dynamically switching the path to be used by the host system is executed.
