Cluster Administration Preparing for Cluster Installation This section provides the steps necessary to cluster HP StorageWorks NAS servers. Before Beginning Installation Confirm that the following specifications have been met before proceeding: ■ The SAN connection tool must be completed and all the necessary software components for connecting to the desired storage must be installed before the configuration of cluster services. ■ It is required that at least one LUN has been presented for the configuration of the Quorum disk. This LUN must be created from shared storage and must be at least 50 MB. (500 MB is recommended). Additional LUNS may also be presented for use as shared disk resources. ■ Cluster configurations should be deployed with dual data paths for high availability. Dual data paths from each node enable a path failure to occur that does not force the failover of the node. Clusters can be configured with single path, but if a failure in the path does occur, all of the node resources will be failed to the non-affected node. HP StorageWorks NAS Software Updates Caution: The version of Storage Manager (Quota Management software located under the Shares tab) that comes installed on the server is not supported in a cluster. It must be uninstalled prior to creating the cluster.The uninstall tool is located in the Cluster Installation Guide under the Cluster tab in the WebUI. See Figure 117.
