About Clusters
Installing on clusters is much the same as a standard installation. To configure Arcserve HA on a cluster, enter the Virtual Server Network Name (or IP Address) resource (in the group you intend to protect) as the Master or Replica name. Do not use node names or IP addresses when configuring the scenario. Also, you must install the Arcserve Continuous Availability Engine to all cluster nodes (see Server Setup).
The only configuration that requires some preparation is the use of IP Move with a cluster. For more information about how you can use Move IP with clusters, please see Cluster Move IP.
