Abstract:
1. In a computer system including a host computer and at least one computer system resource accessible to the host computer, wherein the host computer comprises an operating system and the operating system uses at least one identifier to enable access by the host computer to the at least one computer system resource, the at least one identifier identifying the at least one computer system resource, a method of responding to changes in a configuration of the computer system impacting a manner in which the at least one computer system resource is accessed by the host computer, the method comprising steps of: (A) storing information relating to a first configuration of the computer system at a first point in time, the first configuration relating to a first manner of accessing the at least one computer system resource by the host computer, the first manner of accessing the at least one computer system resource including the use of a first identifier by the operating system to identify the at least one computer system resource; (B) determining a second configuration of the computer system at a second point in time, the second configuration relating to a second manner of accessing the at least one computer system resource by the host computer; (C) comparing the second configuration of the computer system with the first configuration to determine whether the second configuration differs from the first configuration in that the second manner of accessing the at least one computer system resource includes the use of a second identifier by the operating system to identify the at least one computer system resource, wherein the second identifier differs from the first identifier; and (D) when it is determined in the step (C) that the second configuration differs from the first configuration, determining the second identifier used by the operating system in the second manner of accessing the at least one computer system resource by the host computer, wherein the act of determining comprises using at least one component of information that uniquely identifies the at least one computer system resource in a manner that is independent of the second configuration.
