This section covers three upgrade scenarios:
To upgrade NetWare 5.1 servers running Cluster Services to NetWare 6.5 servers running Cluster Services, you need to
If you are upgrading Novell Cluster Services from NetWare 5.1 to NetWare 6.5 and your cluster has shared storage, you must prepare your cluster servers before upgrading them to NetWare 6.5 and before upgrading Novell Cluster Services. This preparation is necessary to ensure existing shared-volume trustee assignments can be used after the upgrade.
NOTE:This is not necessary if you are upgrading from NetWare 6 to NetWare 6.5.
To prepare cluster servers for an upgrade, from a NetWare client run nwdeploy.exe from the root of the NetWare 6.5 Operating System CD to launch the NetWare Deployment Manager, then complete the following steps:
In the NetWare Deployment Manager, open the Network Preparation Folder and then click .
Continue through the screens until you get to the screen that prompts you to select an existing cluster to prepare for upgrade.
Specify the cluster name, eDirectory tree, and context for the cluster you are preparing for upgrade.
Choose whether you want the servers you are going to upgrade to go down after completing the preparation for upgrading cluster servers, then click to run the program for preparing cluster servers for upgrade.
Bringing down all cluster servers before an upgrade ensures NSS volumes on shared storage (your SAN) are deactivated prior to upgrading to NetWare 6.5.
After you have completed the process for preparing cluster servers for an upgrade, continue with Upgrading NetWare 5.1 Servers to NetWare 6.5.
To upgrade your NetWare 5.1 servers to NetWare 6.5, follow
the instructions in Upgrading
to OES NetWare
in the NetWare 6.5 Overview
and Installation Guide.
After upgrading your servers to NetWare 6.5 and rebooting them, continue with Upgrading Novell Cluster Services Software.
The same installation program used to install Novell Cluster Services software is also used to upgrade it. To upgrade Novell Cluster Services software, follow the instructions in Running the Installation Program.
After upgrading cluster software, continue with Completing the Cluster Upgrade.
Complete the cluster upgrade by using the Cluster View option in ConsoleOne. This automatically edits cluster load and unload scripts to remove upgrade-specific commands that were added during the cluster upgrade. It also automatically renames NSS Pool objects that were created during the upgrade and modifies them to reference virtual server objects intead of physical server objects.
Start ConsoleOne and authenticate to the eDirectory tree where the Cluster object resides.
Browse and select the Cluster object for the cluster you just upgraded.
Go to the Cluster State View by clicking from the menu at the top of the screen.
The cluster upgrade process will automatically complete when you open the Cluster State View.
To upgrade NetWare 6 servers running Cluster Services to NetWare 6.5 servers running Cluster Services you need to
Since licenses for a two-node cluster are included with NetWare 6 and with NetWare 6.5, this is only necessary if you are upgrading a three-node or larger cluster. Additional Cluster Server Licenses can be obtained from Novell or from your Novell Authorized Reseller.
Upgrading to OES NetWarein the NetWare 6.5 Overview and Installation Guide.
The latest Cluster Services files are automatically copied to each server during the server upgrade process. When each server reboots after being upgraded, new Cluster Services software will automatically load.
Performing a rolling upgrade from NetWare 6 to NetWare 6.5 lets you keep your cluster up and running and lets your users continue to access the network while the upgrade is being performed.
During a rolling cluster upgrade, one server is upgraded to NetWare 6.5 while the other servers in the cluster continue running NetWare 6. Then another server is upgraded to NetWare 6.5, and then another, until all servers in the cluster have been upgraded to NetWare 6.5.
When the last server in the cluster has been upgraded (all the servers in the cluster are running NetWare 6.5) each cluster-enabled pool resource (or any resource on shared storage) is temporarily put into a new resource state called upgrade, and the following process occurs automatically:
The amount of time users lose access to cluster resources is minimal because the process described above happens very quickly.
To perform a rolling cluster upgrade from NetWare 6 to NetWare 6.5
Install NetWare 6.5 Cluster Server Licenses on your NetWare 6 cluster servers using iManager prior to upgrading them to NetWare 6.5.
Since licenses for a two-node cluster are included with NetWare 6 and with NetWare 6.5, this is only necessary if you are upgrading a three-node or larger cluster. Additional Cluster Server Licenses can be obtained from Novell or from your Novell Authorized Reseller.
Upgrade one NetWare 6 server in the cluster
to NetWare 6.5 by following the instructions in Upgrading
to OES NetWare
in the NetWare 6.5 Overview
and Installation Guide.
The latest Cluster Services files are automatically copied to the server during the upgrade process. When the server reboots after being upgraded, new Cluster Services software will automatically load.
Cluster pools, volumes, and resources fail over from the server being upgraded to other servers in the cluster. After a cluster server is upgraded and brought back online, the pools, volumes, and resources that failed over to other servers during the upgrade process fail back to the upgraded server.
Upgrade another server in the cluster to NetWare 6.5, and continue this process until all servers in the cluster have been upgraded to NetWare 6.5
After a cluster server has been upgraded, you do not need to immediately upgrade another cluster server. The rolling upgrade process allows both NetWare 6 and NetWare 6.5 cluster servers to coexist in the same cluster.
