How Cluster Server (VCS) works with Workload Patitions (WPARs)
VCS provides application management and high availability to applications that run in WPARs. VCS supports only system WPARs; application WPARs are not supported.
You can use VCS to perform the following:
Start, stop, monitor, and failover a WPAR.
Start, stop, monitor, and failover an application that runs in a WPAR.
Tasks for installing and configuring WPARs in VCS environments
Install and configure the WPAR.
Create the VCS service group with the standard application resource types (application, storage, networking) that need to be run inside the WPAR, and the WPAR resource.
VCS represents the WPAR and its state using the WPAR resource.
VCS and the necessary agents run in the global environment. For applications that run in a WPAR, the agents can run some of their functions (entry points) inside the WPAR. If any resource faults, VCS fails over the service group with the WPAR to another node.
