standby), continues to run as standby.

Figure 13 Primary and Standby Packages in Different Clusters
In this configuration, Figure 13 (page 38), two Serviceguard clusters, SG Cluster1 is configured
for the primary package and SG Cluster2 is configured for the standby package. Node1 and
Node2 shares the volume group on which the primary database is configured, primary package
can run on both the nodes. Similarly, the standby database is configured on the volume group that
is shared between Node3 and Node4. Standby package can run on both the nodes.
NOTE: For more information, see When Primary and Standby packages are in the same cluster
