In addition to high availability of applications using ApplicationHA, you can also ensure high availability of the virtualization infrastructure with VCS. By using VCS, you can externally restart managed LPARs and fail over the managed LPARs in case of application failures or managed LPAR failures. To ensure high availability of the virtualization environment, perform the following steps:
Install VCS in the management LPAR.
Enable ApplicationHA capabilities in underlying VCS in the management LPAR.
Install ApplicationHA on the managed LPAR.
Add managed LPAR and HMC as managed hosts to Veritas Operations Manager (VOM) Management Server.
Configure application monitoring on the managed LPAR.
The following figure illustrates the workflow for ensuring high availability of the applications running inside the managed LPAR and the virtualization infrastructure. The figure also indicates the corresponding documents that you must refer for detailed instructions at each step. Review the documents carefully to ensure you install and configure the appropriate versions of each component. The most recent version of VOM MS is recommended
