Planning and Documenting an HA Cluster
General Planning
Chapter 4 91
additional disk hardware for shared data storage. If you intend to
expand your cluster without the need to bring it down, careful planning
of the initial configuration is required. Use the following guidelines:
• Set the Maximum Configured Packages parameter (described later
in this chapter under “Cluster Configuration Planning” on page 105)
high enough to accommodate the additional packages you plan to
add.
• Networks should be pre-configured into the cluster configuration if
they will be needed for packages you will add later while the cluster
is running. See “LAN Information” on page 93.
See Chapter 7, “Cluster and Package Maintenance,” on page 229, for
more information about changing the cluster configuration dynamically,
that is, while the cluster is running.
