The primary cluster is shown in Figure 5-4.
Figure 5-4 Sample Local Cluster Configuration
Configuring a Cluster with Recovery Packages
Use the following steps and the instructions in chapters 4 through 7 of
Managing MC/ServiceGuard manual as guidelines for creating a new
Recovery Cluster or preparing an existing cluster to run in a
ContinentalClusters environment:
1. Configure all hardware. Make sure the cluster hardware is able to
handle the task of running any or all packages it supports in the
ContinentalClusters configuration:
a. If this is a new cluster, make sure the hardware is similar to that
of the other cluster. For example, if V class HP 9000 systems
comprise one cluster, they should be used to build the other.
b. If this is an existing cluster, determine whether you need to add
disks for data replication. This is needed to ensure that there is
enough capacity from system resources to run all packages if
applications fail over to the other cluster. If not, either add nodes
to the existing cluster, or move less critical packages to another
cluster.
