Install Novell Cluster Services on OES Linux by following the instructions provided in the OES 11 Novell Cluster Services 2 for Linux Administration Guide .

The cluster installation process includes:

As you install Novell Cluster Services on Linux, record key information about the cluster on the System Clustering Worksheet:

SYSTEM CLUSTERING WORKSHEET

Under Item 1: eDirectory Tree for Cluster, record the name of the eDirectory tree where the new Cluster object has been created.

Under Item 2: Cluster Name, record the name of the Cluster object that you created for your GroupWise system.

Under Item 3: Cluster Context, record the full context of the Cluster object.

Under Item 4: Nodes in Cluster, list the nodes that you have added to the cluster. Include the file system information about each partition, including file system type (reiserfs, ext3, etc.), device name (sda2, hda1, etc.), and mount point directory (/mnt, /mail, etc.). You need this information when you set up the load and unload scripts for the GroupWise cluster resources.

Under Item 5: Shared Partitions, list the shared partitions that are available for use in your GroupWise system.

The number of nodes and shared partitions that are available in the cluster strongly influences where you can place GroupWise domains and post offices. You have several alternatives:

If you do not have the system resources to run all of your GroupWise system in a clustering environment, you must decide which parts have the most urgent need for the high availability provided by clustering. Here are some suggestions:

There is no right or wrong way to implement GroupWise in a clustering environment. It all depends on the specific needs of your particular GroupWise system and its users.
