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