Introduction to GroupWise 8 and
Novell Cluster Services on
NetWare
Before implementing GroupWise®8 with Novell®Cluster ServicesTM, make sure you have a solid
understanding of Novell Cluster Services by reviewing the following information resources:
AppNote: An Introduction to Novell Cluster Services (http://developer.novell.com/research/
appnotes/1999/may/01/a990501_.pdf)
Novell Open Enterprise Server (OES) Product Documentation: OES Novell Cluster
Services 1.8 Administration Guide for NetWare (http://www.novell.com/documentation/oes/
cluster_admin/data/h4hgu4hs.html#bktitle)
NetWare 6.5 Product Documentation: Novell Cluster Services (http://www.novell.com/
documentation/ncs65)
When you review the information resources recommended above, you discover that clustering
employs very specialized terminology. The following brief glossary provides basic definitions of
clustering terms and relates them to your GroupWise system:
cluster: A grouping of from 2 to 32 NetWare®servers configured using Novell Cluster Services so
that data storage locations and applications can transfer from one server to another without
interrupting their availability to users.
node: A clustered server; in other words, a single NetWare server that is part of a cluster.
resource: An IP address, volume, application, service, and so on, that can function successfully
anywhere in the cluster. The volumes where domains and post offices reside are a specific type of
cluster resources termed “volume resources.” In this section, the terms “cluster resource” and
“volume resource” are used instead of “resource” to avoid confusion with GroupWise resources
(such as conference rooms and projectors).
failover: The process of moving cluster resources from a failed node to a functional node so that
availability to users is uninterrupted. For example, if the node where the POA is running goes down,
the POA and its post office fail over to a secondary node so that users can continue to use
GroupWise. When setting up cluster resources, you need to consider what components need to fail
over together in order to continue functioning.
fan-out-failover: The configuration where cluster resources from a failed node fail over to different
nodes in order to distribute the load from the failed node across multiple nodes. For example, if a
node runs a cluster resource consisting of a domain and its MTA, another cluster resource consisting
of a post office and its POA, and a third cluster resource for WebAccess, each cluster resource can
be configured to fail over separately to different secondary nodes.
failback: The process of returning cluster resources to their preferred node after the situation
causing the failover has been resolved. For example, if a POA and its post office fail over to a
secondary node, that cluster resource can be configured to fail back to its preferred node when the
problem is resolved.

migration: The process of manually moving a cluster resource from its preferred node to a
secondary node for the purpose of performing maintenance on the preferred node, temporarily
lightening the load on the preferred node, and so on.
shared disk system: The hardware housing the physical disk volumes that are shared among the
cluster nodes.
shared volume: A volume in a shared disk system that can be accessed from any cluster node that
needs the data stored on it.
cluster-enabled shared volume: A shared volume for which a Volume Resource object has been
created in Novell eDirectoryTM. The properties of the Volume Resource object provide load and
unload scripts for programs installed on the volume, failover/failback/migration policies for the
volume, and the failover path for the volume. Cluster-enabling is highly recommended for
GroupWise.
GroupWise volume: As used in this section, a cluster-enabled shared volume that is used for
GroupWise, such as for storing a domain, post office, software distribution directory, and so on. This
section also uses the terms Internet Agent volume, WebAccess Agent volume, Messenger volume,
and gateway volume in a similar manner.
storage area network (SAN): The cluster nodes together with their shared disk system and shared
volumes.
virtual server: A logical server, rather than a physical server, to which cluster-enabled shared
volumes are tied.
active/active mode: The configuration of a clustered application where the application runs
simultaneously on multiple nodes in the cluster. Active/active mode is recommended when the
GroupWise MTA, POA, Internet Agent, and WebAccess Agent run in protected memory because
protected memory isolates them from each other, even if they are running on the same node.
active/passive mode: The configuration of a clustered application where the application runs on
only one node at a time in the cluster. The GroupWise MTA, POA, Internet Agent, and WebAccess
Agent must run in active/passive mode if they are not running in protected memory because only
one instance of each agent/database combination can be running at the same time in the cluster.
