One embodiment of the present invention provides a method and an apparatus for verifying configuration of storage devices in a computer system based upon device identifiers within the storage devices. The method and apparatus provide a computer system that reads device identifiers from storage devices in the computer system, and uses the device identifiers to create a mapping associating the device identifiers with corresponding physical paths to the storage devices. Upon reconfiguration of the storage devices, the computer system again reads device identifiers from storage devices in order to verify that the system was reconfigured correctly. In a variation on this embodiment, the computer system additionally associates a logical path with each storage device. When the computer system subsequently receives an access request for the storage device directed to the logical path, the computer system translates the logical path into an associated physical path, and uses the physical path to access the storage device.
