Abstract
A method is disclosed to locate a data storage device disposed in a data storage system. The method selects a target data storage device, identifies a target adapter port in communication with the target data storage device, and determines one or more target addresses, and determines one or more target World Wide Port Names (“WWPNs”). The method selects an enclosure, and a communication pathway disposed in that enclosure, and determines if any storage device ports interconnected with the communication pathway comprise a WWPN that matches any of said target WWPNs. If any storage device ports interconnected with the communication pathway comprise a WWPN that matches any of the target WWPNs, the method then identifies an adapter port in communication with that communication pathway, and determines if that any storage device ports in communication with the identified adapter port have claimed an address that matches a target address. If a storage device port in communication with the identified adapter port has claimed an address that matches a target address, then the method locates the target data storage device within the selected enclosure.
