Upgrading OES 1 Linux Clusters to OES 2 Linux555novdocx (en) 7 January 20105Upgrading OES 1 Linux Clustersto OES 2 LinuxThis section provides information to help you upgrade a Novell® Open Enterprise (OES) 1 Linuxcluster 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 OES: Novell Cluster Services 1.8.2Administration Guide for Linux (http://www.novell.com/documentation/oes/cluster_admin_lx/data/h4hgu4hs.html). Section 5.1, “Requirements and Guidelines for Upgrading Clusters from OES 1 Linux and OES2 Linux,” on page 55 Section 5.2, “Upgrading Existing OES 1 Linux Cluster Nodes to OES 2 (Rolling ClusterUpgrade),” on page 56 Section 5.3, “Adding New OES 2 Linux Cluster Nodes to Your OES 1 Linux Cluster,” onpage 57 Section 5.4, “Modifying Cluster Resource Scripts for Mixed OES 1 Linux and OES 2 LinuxClusters,” on page 57 Section 5.5, “Finalizing the Cluster Upgrade,” on page 575.1 Requirements and Guidelines for UpgradingClusters from OES 1 Linux and OES 2 LinuxIn addition to the Section 3.1, “System Requirements for Novell Cluster Services,” on page 27,consider the following rules and recommendations for mixed OES 1 Linux and OES 2 Linuxclusters: Mixed OES 1 Linux and OES 2 Linux clusters should be considered a temporary configurationthat exists only during an upgrade. Adding an OES 1 Linux cluster node to a mixed-node OES 1 Linux and OES 2 Linux cluster isnot supported If you have configured resource monitoring for a resource running on an OES 2 Linux clusternode, resource monitoring does not function if the resource fails over or is migrated to an OES1 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 theupgrade. No storage management functions should be executed while a cluster is in a mixed-clustermode. Do not attempt to create, delete, expand, or modify the properties for partitions, pools, orvolumes for any shared resources in the cluster.
