Sample Conﬁgurations

Example One - Three-Server Mutual Takeover

	Example One - Three-Server Mutual Takeover
	This conﬁguration has three servers and three Serviceguard NFS
	packages. Each server is the primary node for one package and an
	adoptive node for the other two packages. Figure 3-1 illustrates this
	conﬁguration. Dotted lines indicate which servers are adoptive nodes for
	the packages.
