5-4 Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide Installing the Hardware Setting Up the Nodes Physically preparing the nodes (servers) for a cluster is not very different than preparing them for individual use. You will install all necessary adapters and insert all internal hard disks. You will attach network cables and plug in SCSI and Fibre Channel cables. The primary difference is in setting up the shared storage subsystem. Set up the hardware on one node completely, then set up the rest of the nodes identically to the first one. Do not load any software on any cluster node until all the hardware has been installed in all cluster nodes. Before loading software, read "Installing the Operating System Software and Configuring the RA4000/RA4100 Arrays" in this chapter to understand the idiosyncrasies of configuring a cluster. IMPORTANT: With some possible exceptions, the servers in the cluster must be set up identically. The cluster components common to all nodes in the cluster must be identical, for example, the ProLiant server model, cluster interconnect adapters, amount of memory, cache, and number of CPUs must be the same for each cluster node. It also means the Fibre host adapters must be installed into the same PCI slots in each server. While setting up the physical hardware, follow the installation instructions in your Compaq ProLiant Server Setup and Installation Guide and in your Compaq ProLiant Server Installation poster. When you are ready to install the Fibre Host Adapters and your cluster interconnect adapters, refer to the instructions in the pages that follow. Installing the Fibre Host Adapters Each redundant Fibre Channel Fabric or redundant Fibre Channel Arbitrated Loop (FC-AL) requires at least two Fibre Host Adapters in each cluster node. Install these devices as you would any other PCI adapter. Install two Fibre Host Adapters on the same PCI bus in each server and into the same two PCI slots in each server. If you need specific instructions, see the Compaq StorageWorks Fibre Channel Host Bus Adapter Installation Guide or the Compaq StorageWorks 64-Bit/66 MHz Fibre Channel Host Adapter Installation Guide.
