Abstract

A management station includes a management application that controls zoning within devices manufactured or provided from different vendors within a network, such as a data storage network. The management application receives a generic zone control command from a user to control zoning within a device in the network. The management application translates the zone control command to one or more vendor specific device zone control commands in a vendor specific device command set that is specifically designed to control zoning within devices from a specific vendor. To perform the translation, the management application identifies the vendor of one or more devices that are affected by the zone control command. Based on this identification, the management application selects an appropriate vendor specific device command set that contains vendor specific zone control commands.
