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 guest domains and fail over the guest domains in case of application failures or guest domain failures. To ensure high availability of the virtualization environment, perform the following steps:
Install SFCFSHA on the control domain.
Enable ApplicationHA capabilities in underlying VCS in the control domain.
Install ApplicationHA on the guest domain.
Add guest domain and control domain as managed hosts to Veritas Operations Manager (VOM) Management Server
Configure application monitoring on the guest domain.
The following figure illustrates the workflow for ensuring high availability of the applications running inside the guest domain 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
