1. A method for synchronizing vital product data in one computer processor subsystem with respect to a system of computer processor subsystems, said computer processor subsystems storing at least some vital product data of the other computer processor subsystems of said system, comprising the steps of: said one computer processor subsystem, in response to receiving an update to vital product data of said system from a source computer processor subsystem of said system, examines said update to detect vital product data of said one computer processor subsystem stored by said source computer processor subsystem; and in response to said detected vital product data being incorrect, said one computer processor subsystem forwarding correct vital product data of said one computer processor subsystem to said source computer processor subsystem having said incorrect vital product data.
