Abstract
A method of forwarding a message received by a server to a coupled hardware device in a server cluster where the server cluster is comprised of a default server and a coupled backup server. A look-up table is created in the server for all hardware devices coupled to the server by a server agent. The look-up table relates a unique identifier of a hardware device to a local path. The server agent sends all of the hardware identifiers to the client. Typically, this occurs as the result of a client application requesting this information. The client can then send a message for a hardware device connected to the server. The message is attached to a unique identifier which contains the hardware identifier. The server agent then extracts the identifier from the message. The server then retrieves the look-up table and locates the path in the look-up table for the coupled hardware device based on the hardware identifier parsed from the unique identifier. The message is then forwarded through the path to the hardware device.
