Step 8. Change the initiator ID in the Objects→ Adapter→ Initiator ID menu. For example, you can change the initiator ID to 6. If ID 6 is used by a disk drive, select a different ID. Step 9. Power down the first server. Step 10.
Driver Installation Instructions under Microsoft Windows 2000 Advanced Server After the hardware is set up for the MS cluster configuration, perform the following procedure to configure the driver under Microsoft Windows 2000 Advanced Server. Note that when the Storage Adapter is added after a Windows 2000 Advanced Server installation, the operating system detects it.
• A domain user account for Cluster Service (all nodes must be part of the same domain) • Two network adapters for each node – one for connection to the external network, the other for the node-to-node internal cluster network. If you do not use two network adapters for each node, your configuration is unsupported.
Installing the Peer Processor Device in a Windows Cluster Use the procedure in this section to install the peer processor device in a Windows cluster. Note: These steps apply to both Windows 2000 and Windows Server 2003 clusters. After the shared drives are configured, and both nodes powered up, a prompt for another device to be installed appears.

Installing SCSI Drives This information is provided as a generic instruction set for SCSI drive installations. If the SCSI hard disk vendor’s instructions conflict with the instructions in this section, always use the instructions supplied by the vendor. The SCSI bus listed in the hardware requirements must be configured prior to installation of Cluster Services.
Installing Clusters under Windows 2000 During installation, some nodes are shut down, and other nodes are rebooted. This ensures uncorrupted data on disks attached to the shared storage bus. Data corruption can occur when multiple nodes try to write simultaneously to the same disk that is not yet protected by the cluster software.
permissions on each node. Each node must be a member server, or must be a domain controller inside the same domain. A mix of domain controllers and member servers in a cluster is not supported. 4.7.1 Installing the Microsoft Windows 2000 Operating System Install the Microsoft Windows 2000 operating system on each node.
Figure 4.6 Network and Dial-up Connections Screen Important: Use crossover cables for the network card adapters that access the cluster nodes. If you do not use the crossover cables properly, the system does not detect the network card adapter that accesses the cluster nodes. If the network card adapter is not detected, you cannot configure the network adapters during the Cluster Service installation.
Renaming the Local Area Connections – To clarify the network connection, you can change the name of the Local Area Connection (2). Renaming helps you identify the connection and correctly assign it. Perform the following steps to change the name. Step 1.
Step 9. Set network adapter speed on the private network to 10 Mbytes/s, rather than the default automated speed selection. 10 Mbytes/s is the recommended setting. a. Select the network speed from the drop-down list. Important: Do not use “Auto detect” as the setting for speed. Some adapters can drop packets while determining the speed.
Use long lease periods to assure that a dynamically assigned IP address remains valid in the event that the DHCP server is temporarily lost. In all cases, set static IP addresses for the private network connector. Note that Cluster Service recognizes only one network interface per subnet. 4.7.6 Verifying Connectivity and Name Resolution Perform the following steps to verify that the network adapters are...

Then you would type: Ping 192.168.0.172 10.1.1.1...
4.7.8 Setting Up a Cluster User Account The Cluster Service requires a domain user account under which the Cluster Service can run. Create the user account before installing the Cluster Service. Setup requires a user name and password. This user account should not belong to a user on the domain.
4.7.9 Setting Up Shared Disks Caution: Ensure that Windows 2000 Advanced Server or Windows 2000 Datacenter Server and the Cluster Service are installed and running on one node before you start an operating system on another node. If the operating system is started on other nodes before you install and configure Cluster Service and run it on at least one node, the cluster disks have a high chance of becoming corrupted.
Step 4. Ensure that all shared disks are formatted as NTFS and are designated as Basic. If you connect a new drive, the Write Signature and Upgrade Disk Wizard starts automatically. If this occurs: 1. Click Next to go through the wizard. The wizard sets the disk to dynamic, but you can deselect it at this point to set it to Basic.
Step 3. Repeat steps 1 and 2 for each shared disk. Step 4. Close the Computer Management window. Step 5. Power down node 1 and boot to node 2 to verify the drive letters. 4.7.12 Verifying Disk Access and Functionality Perform these steps to verify disk access and functionality: Step 1.
4.7.13 Installing Cluster Service Software Important: If drive letters were changed, make sure they correspond on each node. Before you begin the Cluster Service Software installation on the first node, ensure that all other nodes are either powered down or stopped and that all shared storage devices are powered on.
Figure 4.8 User Account and Password Validation Step 12. Enter a name for the cluster (up to 15 characters) and click on Next. (In our example, the cluster is named ClusterOne.) Step 13. Type the user name of the Cluster Service account that you created during the pre-installation.
Figure 4.9 Add or Removed Managed Disks Screen 4.7.14 Configuring Cluster Disks The Windows 2000 Managed Disks displays all SCSI disks, as shown on Figure 4.9. It might display SCSI disks that do not reside on the same bus as the system disk. Because of this, a node that has multiple SCSI buses lists SCSI disks that are not to be used as shared storage.
Figure 4.11 Network Connections Dialog Box In production clustering scenarios, you must use more than one private network for cluster communication; this avoids having a single point of failure. Cluster Service can use private networks for cluster status signals and cluster management. This provides more security than using a public network for these roles.
Page 88
The order in which the Cluster Service Configuration Wizard presents these networks can vary. In this example, the public network is presented first. Step 3. Verify that the network name and IP address correspond to the network interface for the public network. Step 4.
networks are used. Because Private Cluster Connection represents a direct connection between nodes, it remains at the top of the list. In normal operation, this connection is used for cluster communication. In case of the Private Cluster Connection failure, Cluster Service automatically switches to the next network on the list (in this case, Public Cluster Connection).
Page 90
Figure 4.14 Cluster IP Address Dialog Box Step 9. Enter the unique cluster IP address and Subnet mask for your network, then click Next. The Cluster Service Configuration Wizard automatically associates the cluster IP address with one of the public or mixed networks.
Figure 4.15 Cluster Service Confirmation Step 11. Click OK. Step 12. Close the Add/Remove Programs window. 4.7.15 Validating the Cluster Installation Use the Cluster Administrator snap-in to validate the Cluster Service installation on the first node. To validate the cluster installation: Step 1.
4.7.16 Configuring the Second Node For this procedure, have node one and all shared disks powered on, then power up the second node. Installation of Cluster Service on the second node takes less time than on the first node. Setup configures the Cluster Service network settings on the second node based on the configuration of the first node.
4.7.17 Verifying Installation There are several ways to verify that Cluster Service was successfully installed. Here is a simple one: Step 1. Select Start—> Programs—> Administrative Tools—> Cluster Administrator. The Cluster Administrator Screen displays, as shown in Figure 4.16. The presence of two nodes shows that a cluster exists and is in operation.
Step 3. Close the Cluster Administrator snap-in. This completes Cluster Service installation on all nodes. The server cluster is fully operational. Now you can install cluster resources, such as file shares, printer spoolers, cluster aware services like IIS, Message Queuing, Distributed Transaction Coordinator, DHCP, WINS, or cluster aware applications like Exchange or SQL Server.
