Page 11: Introduction
1 Introduction This document describes how to install and configure clustered computing solutions using HP Integrity servers running Microsoft® Windows® Server 2003. The clustering improvements for Microsoft Windows Server 2003, 64-bit Edition (over Microsoft Windows 2000) include the following: Larger cluster sizes 64-bit Enterprise and Datacenter Editions now support up to eight nodes. -
Page 12: Server Cluster Versus Network Load Balancing
Public network One or more public networks can be used as a backup for the private network and can be used both for internal cluster communication and to host client applications. Network adapters, known to the cluster as network interfaces, attach nodes to networks. •... -
Page 13: Server Cluster
Table 1-1 Server Cluster and NLB Features (continued) Server Cluster Supports clusters up to eight nodes Supports clusters up to 32 nodes Requires the use of shared or replicated storage Doesn't require any special hardware or software Server Cluster Use a server cluster to provide high availability for mission critical applications through failover. It uses a shared-nothing architecture, which means that a resource can be active on only one node in the cluster at any given time. -
Page 14: Cluster Terminology
Figure 1-1 NLB Example Cluster Terminology A working knowledge of clustering begins with the definition of some common terms. The following terms are used throughout this document. Nodes Individual servers or members of a cluster are referred to as nodes or systems (the terms are used interchangeably). -
Page 15: Resource Dependencies
If the resource cannot be brought online or taken offline after a specified amount of time, and the resource is set to the failed state, you can specify the amount of time that cluster service waits before failing the resource by setting its pending timeout value in Cluster Administrator. Resource state changes can occur either manually (when you use Cluster Administrator to make a state transition) or automatically (during the failover process). -
Page 16: Single Quorum
Arbitration The quorum is used as the tie-breaker to avoid split-brain scenarios. A split-brain scenario occurs when all network communication links between two or more cluster nodes fail. In these cases, the cluster can split into two or more partitions that cannot communicate with each other. The quorum then guarantees that any cluster resource is brought online on one node only. -
Page 17: Majority Node Set (Mns) Quorum
Stateful applications Applications or Windows NT services that require only a single instance at any time and require state information to be stored typically use single quorums, because they already have shared state information storage. Connecting all nodes to a single storage device simplifies transferring control of the data to a backup node. -
Page 18: Heartbeats
In the case of a failure or split-brain, all partitions that do not contain an MNS quorum are terminated. This ensures that if there is a partition running that contains a majority of the nodes, it can safely start up any resources that are not running on that partition. Thus, it can be the only partition in the cluster that is running resources. -
Page 19: Failback
Failback Failback is the process of returning a resource or group of resources to the node on which it was running before it failed over. For example, when node A comes back online, IIS can fail back from node B to node A. Cluster Terminology... -
Page 21: Administering The Cluster
2 Administering the cluster This chapter provides step-by-step installation and configuration directions for HP Integrity clustered systems running Microsoft Windows Server 2003, 64-bit Edition. Verifying Minimum System Requirements To verify that you have all of the required software and firmware and have completed all the necessary setup tasks before beginning your cluster installation, complete the following steps: Before installation, see the HP Cluster Configuration Support website for details about the components that make up a valid cluster configuration. -

Verify that you have sufficient administrative rights to install the OS and other software onto each node. 10. Verify that all of the required hardware is properly installed and cabled (see Figure 2-1). For information about best practices for this step, go to: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/ServerHelp/ f5abf1f9-1d84-4088-ae54-06da05ac9cb4.mspx NOTE:... - Page 23 Table 2-1 Installation and Configuration Input Input Description Value Node name Node 1: Node 2: Node 3: Node 4: Node 5: Node 6: Node 7: Node 8: Public network connection, Node 1: Node 2: IP address, and subnet mask IP address: IP address: for each node Subnet mask:...

Page 25: Configuring The Public And Private Networks
Configuring the Public and Private Networks NOTE: Private and public NICs must be configured in different subnets, otherwise the cluster service and Cluster Administrator utility cannot detect the second NIC. In clustered systems, node-to-node communication occurs across a private network, while client-to-cluster communication occurs across one or more public networks. -
Page 26: Public Networks
Click the General tab. Be sure that only the Internet Protocol (TCP/IP) checkbox is selected. If you have a network adapter that transmits at multiple speeds, manually specify a speed and duplex mode. Do not use an autoselect setting for speed, because some adapters can drop packets while determining the speed. -
Page 27: Nic Teaming
NOTE: If your public network paths are teamed, you must put your teamed connection at the top of the list (instead of the external public network). Repeat Step 1 through Step 7 for each node in the cluster. Be sure to assign a unique IP address to each node while keeping the subnet mask the same for all nodes. -

Install and configure your HP StorageWorks MultiPath for Windows software. For an overview and general discussion of the MultiPath software, go to: http://h18006.www1.hp.com/products/sanworks/secure-path/spwin.html HP MultiPathing IO (MPIO) Device Specific Module software can be used as an alternative to HP StorageWorks Secure Path to provide multipath support. NOTE: You must use MultiPath software if more than one host bus adapter (HBA) is installed in each cluster. -
Page 29: Creating The Cluster
Click the Computer Name tab, and click Change. Select Domain Name and enter the domain name determined by your network administrator. Reboot when prompted and log into the new domain. Install the MultiPath software on this node. All other nodes should be powered Off before completing this step. Click Start Programs Administrative Tools Computer Management Disk Management and select Disk Management. -

In the Action menu list, select Add Nodes to Cluster and click OK. In the Welcome to Add Nodes wizard, click Next. Enter the name of the node you want to add under Computer Name, click Add, then click Next. Cluster analysis begins. NOTE: You can list all the nodes at the same time by entering the name of each one and clicking Add. -
Page 31: Validating Cluster Operation
Validating Cluster Operation To validate your cluster installation, use one or both of the following methods from any node in the cluster. Method 1: Simulate a Failover To simulate a failover, complete the following steps: Select Start Programs Administrative Tools Cluster Administrator and connect to the cluster. - Page 32 With clustered systems, you can do maintenance even when users are online. Wait until a convenient, off-peak time when one of the nodes in the cluster can be taken offline for maintenance and its workload distributed among the remaining nodes. Before the upgrade, however, you must evaluate the entire cluster to verify that the remaining nodes can handle the increased workload.
