6.1 Requirements for Upgrading Clusters

Ensure that your environment meets the requirements for installing Novell Cluster Services that are described in Section 4.0, Planning for Novell Cluster Services.

Novell Cluster Services added support for OES 2 SP3 services and file systems on the SUSE Linux Enterprise Server (SLES) 10 SP4 operating system. You can upgrade to SLES 10 SP4 by using the move-to-sles10-sp4 patch in the SLES patch channel. After a cluster upgrade, all nodes in the cluster must be running on the same SLES 10 release with the latest patches applied.
