High-level overview of how VCS manages LPARs.
Management LPARs form a cluster.
For information about installing VCS, see the Cluster Server Configuration and Upgrade Guide.
CPU and memory resources are made available to create LPARs on all nodes in the cluster.
VCS is installed on all the management LPARs to manage the LPARs.
The operating system is installed on the LPAR on any one host.
The LPAR is configured as an LPAR resource in VCS.
For detailed instructions on creating and configuring a PowerVM guest, see the IBM documentation.
To configure an LPAR for across physical servers, the following conditions apply:
You must configure an LPAR on one node with the operating system installed on a shared storage accessible to all the VCS cluster nodes.
Ensure that the image file resides on the shared storage so that the LPARs can fail over across cluster nodes.
You can configure the first LPAR using the standard installation procedure:
Bundled agents are included with VCS for managing many applications. The LPAR agent is included and can be used to manage and provide high availability for LPARs. For information on LPAR agent attributes, resource dependency and agent function, refer to the Cluster Server Bundled Agents Reference Guide.
