Enabling the ApplicationHA infrastructure for a managed host

Last published : Jun 19, 2026
Using the Management Server console, you can enable the ApplicationHA infrastructure for a selected managed host. This operation creates a private network between the Cluster Server (VCS) cluster and the ApplicationHA host. Using this private network, the ApplicationHA host communicates with the VCS cluster to inform about an application fault.
You can also use this feature to configure the auto-registration option of the VCS cluster. The auto-registration feature enables automated communication over the private network between the virtual machines and the infrastructure host, provided that the ApplicationHA is configured on the virtual machines.
To perform this task, your user group must be assigned the Admin role or the Operator role on the cluster or the Availability perspective. The permission on the cluster may be explicitly assigned or inherited from a parent Organization.
This operation can be performed only on Kernel-based Virtual Machine (KVM), Logical Domains (LDOM), and logical partition (LPAR) virtual machines.
To enable the ApplicationHA infrastructure for a managed host
  1. In the Management Server console, go to the Availability perspective and selectManage in the left pane.
  2. Expand the Organization or Uncategorized Clusters to locate the cluster.
  3. Expand the cluster and then expand the Systems node to locate the system.
  4. Right-click on the system and select ApplicationHA Infrastructure>Enable.
  5. In the Enable ApplicationHA Infrastructure panel, click OK to confirm.
