Before you install a ZENworks Server Management component in a clustered environment, you must install Novell Cluster Services and perform some preparatory tasks:
ZENworks Server Management components can be installed in a cluster that meets the following minimum requirements:
DNS
DNS must be functioning reliably throughout your network so that DNS hostnames and IP addresses can always be successfully resolved.
NetWare 6.5 with SP4 or SP5
or
OES NetWare with SP2
or
OES Linux with SP1
IMPORTANT:ZENworks does not support mixed NetWare and Linux operating systems within a cluster.
Novell iManager for administering ZENworks Server Management in the cluster
Novell ConsoleOne® for administering Server Inventory in the cluster
Cluster-enabling the shared volumes where ZENworks Server Management components are installed is required.
To review the concept of cluster-enabled shared volumes, see the applicable section of Novell Cluster Services Overview and Installation for your version of NetWare:
NetWare 6.5: Cluster-Enabling Shared Volumes for Use with ZfS Components
NetWare 6: Cluster Enable Pools and Volumes
NetWare 5.1: Cluster-Enable Volumes
When you cluster enable a volume, additional eDirectory objects are created:
IMPORTANT:The default object names include the underscore (_) character. However, DNS name servers cannot resolve object names that include underscore characters. If you have met the requirements described in Section F.3.1, Meeting System Requirements for Clustering, you can rename these objects as needed when you cluster enable the volume.
To cluster enable a shared volume for use with a ZENworks Server Management component:
Complete the steps in the applicable section of Novell Cluster Services Overview and Installation for your version of NetWare:
NetWare 6.5: Cluster-Enabling Shared Volumes for Use with ZfS Components
NetWare 6: Cluster Enable Pools and Volumes
NetWare 5.1: Cluster-Enable Volumes
If necessary, rename cluster-related objects to eliminate the underscore (_) characters that are included by default.
Repeat Step 1 and Step 2 above for the other shared volumes that need to be cluster-enabled for use with ZENworks Server Management components.
Install a ZENworks Server Management component in the cluster, following the instructions in:
Install Novell Cluster Services by following the instructions provided in NetWare Cluster Services Overview and Installation for your version of NetWare:
NetWare 6.5: Installing ZENworks for Servers in a Clustered Environment
NetWare 6: Installation and Setup
NetWare 5.1: Installation and Setup
The installation process includes:
Meeting hardware and software requirements for Novell Cluster Services
Setting up a shared disk system
Creating a new Cluster object to represent the cluster in eDirectory
Adding servers to the cluster
Installing the Novell Cluster Services software on all nodes in the cluster
Mounting the shared volumes where you install ZENworks Server Management components
As you install Novell Cluster Services, record key information about the cluster. You need the following information as you install ZENworks Server Management components in the cluster:
eDirectory tree where you create the Cluster object
Name of the Cluster object
Context of the Cluster object
