DRAFT Network requirements ■ A unique NetBIOS cluster name ■ Five unique, static IP addresses: two for the network adapters on the private network, two for the network adapters on the public network, and one for the cluster itself. ■ A domain user account for Cluster service (all nodes must be members of the same domain) ■ Each node should have at least two network adapters-one for connection to the public network and the other for the node-to-node private cluster network. If only one network adapter is used for both connections, the configuration is unsupported. A separate private network adapter is required for HCL certification. Shared disk requirements Template date: 09/2003 Note: Do not let more than one node access the shared storage devices at the same time until Cluster service is installed on at least one node and that node is online. This can be accomplished through selective storage presentation, SAN switch zoning or having only one node online at all times. ■ All software components listed in the SAN connection tool must be installed and the fibre cables attached to the HBA(s) before the cluster installation is started. ■ All shared disks, including the quorum disk, must be accessible from all nodes. ■ All shared disks must be configured as basic (not dynamic). ■ All partitions on the disks must be formatted as NTFS. Cluster installation overview During the installation process, nodes will be shut down and rebooted. These steps are necessary to guarantee that the data on disks that are attached to the shared storage bus is not lost or corrupted. This can happen when multiple nodes try to simultaneously write to the same disk that is not yet protected by the cluster software. NAS 4000s and 9000s Installation Guide 35 HP Restricted
