Download technology levels and service packs using SUMA for a specific client in NIM server

Generally, Service Update Management Assistant (SUMA) is supposed to download fix packs corresponding to the operating system (OS) level of the system in which it runs. However, in a Network Installation Management (NIM) environment, you might want the NIM server to have fix packs applicable to NIM clients which are at earlier levels than that of the server and use the same to update the clients.
