		See if the required NIM resources are created on the local server.
		
		Create local definitions if necessary.

		Runs only on service nodes that are not the NIM primary

		Supports the following NIM resources:

            installp_bundle, lpp_source, script, paging
            root, shared_home, spot, tmp, resolv_conf

		Also does the NIM setup for additional networks if necessary.
