Upgrading OES 1 Linux Clusters

to OES 2 Linux

This section provides information to help you upgrade a Novell

cluster to OES 2 Linux, and how to manage the temporarily mixed cluster during the upgrade.

For information about managing an OES 1 Linux cluster, see the

Administration Guide for Linux (http://www.novell.com/documentation/oes/cluster_admin_lx/data/

5.1 Requirements and Guidelines for Upgrading

Clusters from OES 1 Linux and OES 2 Linux

In addition to the

Section 3.1, "System Requirements for Novell Cluster Services," on page

consider the following rules and recommendations for mixed OES 1 Linux and OES 2 Linux

clusters:

Mixed OES 1 Linux and OES 2 Linux clusters should be considered a temporary configuration

that exists only during an upgrade.

Adding an OES 1 Linux cluster node to a mixed-node OES 1 Linux and OES 2 Linux cluster is

not supported

If you have configured resource monitoring for a resource running on an OES 2 Linux cluster

node, resource monitoring does not function if the resource fails over or is migrated to an OES

1 Linux cluster node.

The use of EVMS is recommended for upgrading file system resources.

You should ensure that all resource policies are configured to the settings that existed before the

upgrade.

No storage management functions should be executed while a cluster is in a mixed-cluster

mode. Do not attempt to create, delete, expand, or modify the properties for partitions, pools, or

volumes for any shared resources in the cluster.
