The following are the requirements for providing high availability of the virtualization environment:
Install VCS on the management LPAR. For each physical server, you can have only one management LPAR running VCS.
Refer to Symantec Cluster Server Installation Guide - AIX
Review the settings of the virtualization environment for which you want to provide high availability
Refer to Symantec Storage Foundation and High Availability Solutions Virtualization Guide - AIX
Symantec recommends that you set the autorestart attribute of the managed LPARs to false, to allow VCS to control it.
Ensure that SSH communication with management LPAR, is enabled on HMC
Enable ApplicationHA capabilities for underlying VCS.
Refer to Symantec ApplicationHA User's Guide - AIX on IBM PowerVM
