Configuring Mulitple Nodes to Support
Failover of Multiple Packages
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. Figure 3-2 illustrates the configuration after host basil
fails.
Figure 3-1 Three-Server Mutual Takeover
Figure 3-2 shows the three-server mutual takeover configuration after
host basil has failed and host sage has adopted pkg02. Dotted lines
indicate which servers are adoptive nodes for the packages.
