ZENworks for Desktops 4.0.1 components are considered "cluster-safe," which means that you can install the ZfD 4.0.1 services in a Novell Cluster Services environment, but if the cluster volume goes down, there will be an interruption in services while the cluster fails over.
When failover occurs, most of the ZfD services will be restored but Workstation Imaging must be restarted and some group policies that rely on a single resource (that is, a server where the policy files are copied) will time-out waiting for the resource to become available. The policies won't be applied until the next login or scheduled event occurs and the file resource becomes available again.
For more information about Novell Cluster Services, see the Novell Cluster Services documentation at the NetWare 5.1 documentation Web site or the NetWare 6 documentation Web site.
