You can use the enable_applicationha script to put a VCS node (management LPAR), that is configured to support ApplicationHA, into maintenance mode.

You can do so by using the following command:

# enable_applicationha -reset

This configuration step resets the ApplicationHA configuration on the VCS node where you run the script. You can put all the nodes in a VCS cluster, one by one, into maintenance mode.

When you put the last node into maintenance mode, global ApplicationHA settings such as IP addresses and DHCP resources are also deleted across the VCS cluster.

ApplicationHA, however, continues to monitor applications on the configured managed LPARs
