5-8 Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide Figure 5-2 shows two RA4000/RA4100 Arrays connected to two clustered servers through one redundant Fibre Channel Fabric or redundant FC-AL. The Fibre Channel Fabric or FC-AL is redundant because there are two paths from each node to each RA4000/RA4100 Array. Fibre Host Adapters (2) Node 1 Storage Hub/Switch #1 Fibre Host Adapters (2) Node 2 Storage Hub/Switch #2 RA4000/4100 Array #1 RA4000/4100 Array #2 Figure 5-2. RA4000/RA4100 Arrays connected to clustered servers through one redundant Fibre Channel Fabric or redundant FC-AL IMPORTANT: Although you can configure the RA4000/RA4100 Array with a single drive installed, it is strongly recommended for cluster configuration that all shared drives be in the RA4000/RA4100 Array before running the Compaq Array Configuration Utility. Compaq Array Configuration Utility The Array Configuration Utility is used to set up the hardware aspects of any drives attached to a RA4000 Array Controller, including the drives in the shared RA4000/RA4100 Arrays. The Array Configuration Utility stores the drive configuration information on the drives themselves; therefore, after you have configured the drives from one of the cluster nodes, it is not necessary to configure the drives from the other cluster node. Before you run the Array Configuration to set up your drive arrays during the SmartStart installation, review the instructions in the "Installing the Operating System Software and Configuring the RA4000/RA4100 Arrays" section of this chapter. These instructions include clustering information that is not included in the Compaq StorageWorks RAID Array 4000 User Guide or the Compaq StorageWorks RAID Array 4100 User Guide.
