Virtual Cluster Nodes In Separate Clusters; Mixed Physical And Virtual Node Clusters - Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual

12.4 Virtual Cluster Nodes in Separate Clusters

In this scenario, you have OES 2 Linux (Xen) installed and configured on each node (physical
machine). You then create multiple NetWare or Linux virtual machines on each physical machine
and install and configure Novell Cluster Services on each virtual machine. During the Novell
Cluster Services installation, you create separate clusters of virtual cluster nodes, with each virtual
cluster node residing on a separate physical machine. This way you have multiple clusters of virtual
cluster nodes on fewer physical machines.
IMPORTANT: All virtual cluster nodes in the same cluster should be either Linux or NetWare. Do
not mix Linux and NetWare cluster nodes in the same cluster.
You can then create and configure cluster resources on each virtual cluster node and cluster. The
process for creating and configuring cluster resources on a virtual cluster node is the same as on a
physical cluster node.
Figure 12-3 depicts using virtual cluster nodes in separate clusters.

12.5 Mixed Physical and Virtual Node Clusters

This is a temporary scenario that is used for upgrading cluster nodes or converting clusters from
physical to virtual cluster nodes.
