Cluster Interconnect

ProLiant Clusters for SCO UnixWare 7 with the ProLiant ML370 server can

use either a high-speed ServerNet I network or a dedicated, private Ethernet

network to connect the cluster nodes. The cluster nodes use the interconnect

data path to support the following cluster features:

■ Cluster-wide file system

■ Cluster-wide process management, migration, and load balancing

■ Cluster-wide networking and Cluster Virtual IP (CVIP)

■ Cluster-wide system administration and management

The ServerNet I cluster interconnect uses two ServerNet I PCI adapters and

two ServerNet I cables to connect the nodes. The Ethernet cluster interconnect

uses the embedded NICs and an Ethernet crossover cable to connect the two

nodes.

1-4 Compaq ProLiant Clusters for SCO UnixWare 7 U/300 Quick Install Guide for the Compaq ProLiant ML370

Cluster Integrity Serial Cable

The Cluster Integrity (CI) serial cable listed with the server components is required for the U/300 Quick Install cluster for the ProLiant ML370 server.

This cable prevents the condition in which more than one node in a cluster acts as the root node and operates as the root node. Because the active root node mounts the root file system and runs several critical cluster-wide functions, more than one node trying to behave as the root node is undesirable.

NOTE: The CI serial cable may be referred to as the split-brain avoidance (SBA) serial cable in UnixWare software and documentation.

Hardware Configuration

The U/300 kit for the ProLiant ML370 server supports the server and storage hardware in specific configurations based on the type of cluster interconnect. The CI serial cable is required for all configurations.

A ServerNet I cluster interconnect uses the two ServerNet I PCI adapters and two cables as shown in Figure 1-1.

LAN Connection

Clusters using Ethernet interconnect require an NC3123 NIC installed into

slot 1 of each node before cluster software installation so that the cluster can

access a public network. These NICs must be on a different subnet from the

embedded Ethernet cluster interconnect. Multiple public network controllers

can be installed after cluster installation is complete. For a list of certified

NICs, see the Compaq High Availability website at

http://www.compaq.com/highavailability

Clusters that use ServerNet I interconnect access the public network using the

embedded NIC. Each server must be connected to the same network.

Transporting Racks

Before transporting a filled rack, read the documentation that comes with the rack to determine the safety measures to take for successful transportation. Never transport a rack without first reviewing the documentation.

Develop standard procedures for securing rack equipment depending on the rack and its components. Standard procedures include:

■ Verify that the rack is secured to the pallet.

■ Remove all loose items from the rack and the pallet.

■ Disconnect the cabling, ensuring that cables are disconnected from any

expansion cabinets and that you have labeled the cables for trouble-free reconnection. Protect, coil, and stow the cables in the cabinet base.

■ Confirm that all major cable bundles are well-secured.

■ Insert anti-static foam between components in the rack.

■ Wrap the front and rear doors of the rack in bubble wrap before securely

closing them.

■ Crate the rack according to the documentation that comes with the rack,

including protective wrapping, banding components, and any external packaging.

■ Label the crate properly with handling information, using statements

such as This End Up, No Forklifts, Top Heavy, and Do Not Double Stack.

■ Include tilt watch for X and Y directions and shock watch indicators.

Use these guidelines in addition to rack documentation to secure the rack for transportation.

Setting Up the Cluster Nodes

Setting up the cluster nodes includes:

■ Installing the 64-bit Fibre Channel Host Bus Adapter (HBA) into slot 3

of each node and Gigabit Interface Converters Shortwave (GBIC-SW) into each adapter

■ Installing one 9.1-GB or larger internal disk drive on each node

■ Installing the public LAN NIC Compaq NC3123 Fast Ethernet NIC

(NC3123 NIC) PCI 10/100 WOL into slot 1 for clusters using Ethernet interconnect

■ Installing the ServerNet I cluster interconnect

NOTE: No installation is required for Ethernet interconnects, which use the embedded NIC. Refer to the section, “Cabling the Ethernet Interconnect,” later in this chapter for installing the Ethernet interconnect cable.

Additional options, such as tape drives, other NICs, and Remote Insight

Lights-Out Edition boards can be installed after the cluster Quick Install

procedure has completed.

Setting Up Cluster Hardware 2-5

Installing the 64-Bit External Storage Fibre Channel HBA and GBIC-SWs

For a redundant fault-tolerant configuration, the storage system connects to

both ProLiant ML370 servers, so an HBA must be installed in each server.

Additionally, a GBIC-SW must be installed in each adapter.

The following steps explain how to install the external Fibre Channel HBAs,

which are required for the Compaq StorageWorks RAID Array 4100

(RA4100):

NOTE: Refer to the ProLiant ML370 server documentation for general PCI adapter installation information.

1. Install one 64-bit HBA into slot 3 of each node.

IMPORTANT: Only one Fibre Channel HBA is supported in each node.

2. Install one GBIC-SW module into each HBA. For installation

instructions, refer to the documentation that comes with the Fibre Channel hardware.

2-6 Compaq ProLiant Clusters for SCO UnixWare 7 U/300 Quick Install Guide for the Compaq ProLiant ML370

3. Do not install or update drivers. The Quick Install procedures install the

Fibre Channel drivers.

Installing Internal Disk Drives

One 9.1-GB disk drive is required per node. The Quick Install automatically configures each internal drive with a 9.1-GB partition, even if the disk drive is larger than 9.1-GB. This UnixWare partition cannot be modified, and other UnixWare partitions cannot be added to this disk drive. After the Quick Install is completed, non-UnixWare partitions can be added up to the maximum capacity of the disk drive, or other disk drives can be installed for additional partitions.

To install the internal disk drives, refer to the documentation included with the drive and with the ProLiant ML370 server.

Installing the Public LAN NIC into a Cluster Ethernet Interconnect

To connect a cluster using Ethernet interconnect to a public network, install an NC3123 NIC into slot 1 of each node using the documentation that comes with the NIC. This step is not needed for clusters that use the ServerNet I interconnect.

Installing the ServerNet I Cluster Interconnect

If your ProLiant ML370 cluster uses ServerNet I as the cluster interconnect, you must install the ServerNet I PCI adapter into slot 1 of each server. To install the ServerNet I PCI adapter, refer to the documentation that comes with the adapter for general installation guidelines.

■ Install one ServerNet I PCI adapter version 1.5e into slot 1 of each node.

■ Ignore the ServerNet I driver installation instructions in the adapter

installation guide. The required UnixWare ServerNet I device driver is included with the SCO UnixWare 7 NonStop Clusters software and is automatically installed during software installation.

■ Ignore the ServerNet I connection testing instructions in the adapter

installation guide. The software installation procedure includes testing the connection.

Setting Up the External Storage Hardware

IMPORTANT: The RA4100 is shipped with a single RAID controller. Each RA4100 array

used in Compaq ProLiant Clusters for SCO UnixWare 7 requires an additional, redundant controller.

NOTE: The Quick Install automatically configures an RA4100 drive with a RAID 1 9.1-GB UnixWare partition, even if the disk drive is larger than 9.1-GB. This partition cannot be modified and other UnixWare disk drive partitions cannot be added to this disk drive. After the Quick Install is completed, non-UnixWare partitions can be added up to the maximum capacity of the disk drive, or other disk drives can be installed for additional UnixWare partitions.

The U/300 cluster for the ProLiant ML370 server uses external storage with

the following components:

■ RA4100 storage subsystem

■ Two Compaq StorageWorks RAID Array 4000 (RA4000) controllers,

one included in the RA4100 storage

■ Two GBIC-SWs, one in each controller

■ Two 9.1-GB or larger disk drives

Setting Up Cluster Hardware 2-7

■ Fibre Channel cables

To configure the external storage for the U/300 Quick Install cluster, set up the

RA4100 storage subsystem according to the following steps:

1. Follow the set-up instructions in the documentation that comes with the

subsystem to set up the RA4100.

Review the section, “Fibre Channel Cable Precautions,” later in this

chapter for general information.

2. Refer to the user guide for the RA4100 for disk drive RAID array

options and considerations.
