Abstract
Structure, Structure, system, apparatus, method, and computer program for managing and configuring a computer storage system by mapping the topology and connectivity of all servers, storage devices, and storage device controllers within the storage subsystem, based on unique identifiers especially World Wide Number (WWN) identifiers. The method includes querying a server to identify host bus adapters coupled to the server, querying each host bus adapter to identify attached device controllers, issuing a read connection information command to the device controller and returning the connection results including identifying devices coupled to the device controller, and storing the returned connection results in a data structure.
