Example One - Three-Server Mutual Takeover

This conﬁguration has three servers and three MC/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.
