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.
