Introduction

A server cluster is a group of independent servers running Cluster service and working collectively as a single system. Server clusters provide high-availability, scalability, and manageability for resources and applications by grouping multiple servers running Windows® 2000 Advanced Server or Windows 2000 Datacenter Server.

The purpose of server clusters is to preserve client access to applications and resources during failures and planned outages. If one of the servers in the cluster is unavailable due to failure or maintenance, resources and applications move to another available cluster node.

For clustered systems, the term high availability is used rather than fault-tolerant, as fault tolerant technology offers a higher level of resilience and recovery. Fault-tolerant servers typically use a high degree of hardware redundancy plus specialized software to provide near-instantaneous recovery from any single hardware or software fault. These solutions cost significantly more than a clustering solution because organizations must pay for redundant hardware that waits idly for a fault. Fault-tolerant servers are used for applications that support high-value, high-rate transactions such as check clearinghouses, Automated Teller Machines (ATMs), or stock exchanges.

While Cluster service does not guarantee non-stop operation, it provides availability sufficient for most mission-critical applications. Cluster service can monitor applications and resources, automatically recognizing and recovering from many failure conditions. This provides greater flexibility in managing the workload within a cluster, and improves overall availability of the system.

Cluster service benefits include:

  • High Availability. With Cluster service, ownership of resources such as disk drives and IP addresses is automatically transferred from a failed server to a surviving server. When a system or application in the cluster fails, the cluster software restarts the failed application on a surviving server, or disperses the work from the failed node to the remaining nodes. As a result, users experience only a momentary pause in service.

  • Failback. Cluster service automatically re-balances the workload in a cluster when a failed server comes back online.

  • Manageability. You can use the Cluster Administrator to manage a cluster as a single system and to manage applications as if they were running on a single server. You can move applications to different servers within the cluster by dragging and dropping cluster objects. You can move data to different servers in the same way. This can be used to manually balance server workloads and to unload servers for planned maintenance. You can also monitor the status of the cluster, all nodes and resources from anywhere on the network.

  • Scalability. Cluster services can grow to meet rising demands. When the overall load for a cluster-aware application exceeds the capabilities of the cluster, additional nodes can be added.

This paper provides instructions for installing Cluster service on servers running Windows 2000 Advanced Server and Windows 2000 Datacenter Server. It describes the process of installing the Cluster service on cluster nodes. It is not intended to explain how to install cluster applications, but rather to guide you through the process of installing a typical, two-node cluster itself.

Checklists for Cluster Server Installation

This checklist assists you in preparing for installation. Step-by-step instructions begin after the checklist.

Software Requirements

  • Microsoft Windows 2000 Advanced Server or Windows 2000 Datacenter Server installed on all computers in the cluster.

  • A name resolution method such as Domain Naming System (DNS), Windows Internet Naming System (WINS), HOSTS, etc.

  • Terminal Server to allow remote cluster administration is recommended.

Hardware Requirements

  • The hardware for a Cluster service node must meet the hardware requirements for Windows 2000 Advanced Server or Windows 2000 Datacenter Server. These requirements can be found at The Product Compatibility Search page

  • Cluster hardware must be on the Cluster Service Hardware Compatibility List (HCL). The latest version of the Cluster Service HCL can be found by going to the Windows Hardware Compatibility List and then searching on Cluster.

    Two HCL-approved computers, each with the following:

    • A boot disk with Windows 2000 Advanced Server or Windows 2000 Datacenter Server installed. The boot disk cannot be on the shared storage bus described below.

    • A separate PCI storage host adapter (SCSI or Fibre Channel) for the shared disks. This is in addition to the boot disk adapter.

    • Two PCI network adapters on each machine in the cluster.

    • An HCL-approved external disk storage unit that connects to all computers. This will be used as the clustered disk. A redundant array of independent disks (RAID) is recommended.

    • Storage cables to attach the shared storage device to all computers. Refer to the manufacturers' instructions for configuring storage devices. If an SCSI bus is used, see Appendix A for additional information.

    • All hardware should be identical, slot for slot, card for card, for all nodes. This will make configuration easier and eliminate potential compatibility problems.

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 two network adapters—one for connection to the public network and the other for the node-to-node private cluster network. If you use only one network adapter for both connections, your configuration is unsupported. A separate private network adapter is required for HCL certification.

Shared Disk Requirements:

  • All shared disks, including the quorum disk, must be physically attached to a shared bus.

  • Verify that disks attached to the shared bus can be seen from all nodes. This can be checked at the host adapter setup level. Please refer to the manufacturer's documentation for adapter-specific instructions.

  • SCSI devices must be assigned unique SCSI identification numbers and properly terminated, as per manufacturer's instructions.

  • All shared disks must be configured as basic (not dynamic).

  • All partitions on the disks must be formatted as NTFS.

While not required, the use of fault-tolerant RAID configurations is strongly recommended for all disks. The key concept here is fault-tolerant raid configurations—not stripe sets without parity.

Cluster Installation

Installation Overview

During the installation process, some nodes will be shut down and some nodes will be 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.

Use Table 1 below to determine which nodes and storage devices should be powered on during each step.

The steps in this guide are for a two-node cluster. However, if you are installing a cluster with more than two nodes, you can use the Node 2 column to determine the required state of other nodes.

Several steps must be taken prior to the installation of the Cluster service software. These steps are:

  • Installing Windows 2000 Advanced Server or Windows 2000 Datacenter Server on each node.

  • Setting up networks.

  • Setting up disks.

Perform these steps on every cluster node before proceeding with the installation of Cluster service on the first node.

To configure the Cluster service on a Windows 2000-based server, your account must have administrative permissions on each node. All nodes must be member servers, or all nodes must be domain controllers within the same domain. It is not acceptable to have a mix of domain controllers and member servers in a cluster.

Installing the Windows 2000 Operating System

Please refer to the documentation you received with the Windows 2000 operating system packages to install the system on each node in the cluster.

This step-by-step guide uses the naming structure from the "Step-by-Step Guide to a Common Infrastructure for Windows 2000 Server Deployment" http://www.microsoft.com/windows2000/techinfo/planning/server/serversteps.asp. However, you can use any names.

You must be logged on as an administrator prior to installation of Cluster service.

Setting up Networks

Note: For this section, power down all shared storage devices and then power up all nodes. Do not let both nodes access the shared storage devices at the same time until the Cluster service is installed on at least one node and that node is online.

Each cluster node requires at least two network adapters—one to connect to a public network, and one to connect to a private network consisting of cluster nodes only.

The private network adapter establishes node-to-node communication, cluster status signals, and cluster management. Each node's public network adapter connects the cluster to the public network where clients reside.

Verify that all network connections are correct, with private network adapters connected to other private network adapters only, and public network adapters connected to the public network. The connections are illustrated in Figure 1 below. Run these steps on each cluster node before proceeding with shared disk setup.

Figure 1: Example of two-node cluster (clusterpic.vsd)

Figure 1: Example of two-node cluster (clusterpic.vsd)

Configuring the Private Network Adapter

Perform these steps on the first node in your cluster.

  1. Right-click My Network Places and then click Properties.

  2. Right-click the Local Area Connection 2 icon.

    Note: Which network adapter is private and which is public depends upon your wiring. For the purposes of this document, the first network adapter (Local Area Connection) is connected to the public network, and the second network adapter (Local Area Connection 2) is connected to the private cluster network. This may not be the case in your network.

  3. Click Status. The Local Area Connection 2 Status window shows the connection status, as well as the speed of connection. If the window shows that the network is disconnected, examine cables and connections to resolve the problem before proceeding. Click Close.

  4. Right-click Local Area Connection 2 again, click Properties, and click Configure.

  5. Click Advanced. The window in Figure 2 should appear.

  6. Network adapters on the private network should be set to the actual speed of the network, rather than the default automated speed selection. Select your network speed from the drop-down list. Do not use an Auto-select setting for speed. Some adapters may drop packets while determining the speed. To set the network adapter speed, click the appropriate option such as Media Type or Speed.

    Bb727114.cluste02(en-us,TechNet.10).gif

    Figure 2: Advanced Adapter Configuration (advanced.bmp)

    All network adapters in the cluster that are attached to the same network must be identically configured to use the same Duplex Mode, Flow Control, Media Type, and so on. These settings should remain the same even if the hardware is different.

    Note: We highly recommend that you use identical network adapters throughout the cluster network.

  7. Click Transmission Control Protocol/Internet Protocol (TCP/IP).

  8. Click Properties.

  9. Click the radio-button for Use the following IP address and type in the following address: 10.1.1.1. (Use 10.1.1.2 for the second node.)

  10. Type in a subnet mask of 255.0.0.0.

  11. Click the Advanced radio button and select the WINS tab. Select Disable NetBIOS over TCP/IP. Click OK to return to the previous menu. Do this step for the private network adapter only.

    The window should now look like Figure 3 below.

    Bb727114.cluste03(en-us,TechNet.10).gif

    Figure 3: Private Connector IP Address (ip10111.bmp)

Configuring the Public Network Adapter

Note: While the public network adapter's IP address can be automatically obtained if a DHCP server is available, this is not recommended for cluster nodes. We strongly recommend setting static IP addresses for all network adapters in the cluster, both private and public. If IP addresses are obtained via DHCP, access to cluster nodes could become unavailable if the DHCP server goes down. If you must use DHCP for your public network adapter, use long lease periods to assure that the dynamically assigned lease address remains valid even if the DHCP service is temporarily lost. In all cases, set static IP addresses for the private network connector. Keep in mind that Cluster service will recognize only one network interface per subnet. If you need assistance with TCP/IP addressing in Windows 2000, please see Windows 2000 Online Help.

Rename the Local Area Network Icons

We recommend changing the names of the network connections for clarity. For example, you might want to change the name of Local Area Connection (2) to something like Private Cluster Connection. The naming will help you identify a network and correctly assign its role.

  1. Right-click the Local Area Connection 2 icon.

  2. Click Rename.

  3. Type Private Cluster Connection into the textbox and press Enter.

  4. Repeat steps 1-3 and rename the public network adapter as Public Cluster Connection.

    Bb727114.cluste04(en-us,TechNet.10).gif

    Figure 4: Renamed connections (connames.bmp)
  5. The renamed icons should look like those in Figure 4 above. Close the Networking and Dial-up Connections window. The new connection names automatically replicate to other cluster servers as they are brought online.

Verifying Connectivity and Name Resolution

To verify that the private and public networks are communicating properly, perform the following steps for each network adapter in each node. You need to know the IP address for each network adapter in the cluster. If you do not already have this information, you can retrieve it using the ipconfig command on each node:

  1. Click Start, click Run and type cmd in the text box. Click OK.

  2. Type ipconfig /all and press Enter. IP information should display for all network adapters in the machine.

  3. If you do not already have the command prompt on your screen, click Start, click Run and typing cmd in the text box. Click OK.

  4. Type ping ipaddress where ipaddress is the IP address for the corresponding network adapter in the other node. For example, assume that the IP addresses are set as follows:

    Node

    Network Name

    Network Adapter IP Address

    1

    Public Cluster Connection

    172.16.12.12.

    1

    Private Cluster Connection

    10.1.1.1

    2

    Public Cluster Connection

    172.16.12.14

    2

    Private Cluster Connection

    10.1.1.2

In this example, you would type ping 172.16.12.14 and ping 10.1.1.2 from Node 1, and you would type ping 172.16.12.12 and 10.1.1.1 from Node 2.

To verify name resolution, ping each node from a client using the node's machine name instead of its IP number. For example, to verify name resolution for the first cluster node, type ping hq-res-dc01 from any client.

Verifying Domain Membership

All nodes in the cluster must be members of the same domain and able to access a domain controller and a DNS Server. They can be configured as member servers or domain controllers. If you decide to configure one node as a domain controller, you should configure all other nodes as domain controllers in the same domain as well. In this document, all nodes are configured as domain controllers.

Note: See More Information at the end of this document for links to additional Windows 2000 documentation that will help you understand and configure domain controllers, DNS, and DHCP.

  1. Right-click My Computer, and click Properties.

  2. Click Network Identification. The System Properties dialog box displays the full computer name and domain. In our example, the domain name is reskit.com.

  3. If you are using member servers and need to join a domain, you can do so at this time. Click Properties and following the on-screen instructions for joining a domain.

  4. Close the System Properties and My Computer windows.

Setting Up a Cluster User Account

The Cluster service requires a domain user account under which the Cluster service can run. This user account must be created before installing Cluster service, because setup requires a user name and password. This user account should not belong to a user on the domain.

  1. Click Start, point to Programs, point to Administrative Tools, and click Active Directory Users and Computers

  2. Click the + to expand Reskit.com (if it is not already expanded).

  3. Click Users.

  4. Right-click Users, point to New, and click User.

  5. Type in the cluster name as shown in Figure 5 below and click Next.

    Bb727114.cluste05(en-us,TechNet.10).gif

    Figure 5: Add Cluster User (clusteruser.bmp)
  6. Set the password settings to User Cannot Change Password and Password Never Expires. Click Next and then click Finish to create this user.

    Note: If your administrative security policy does not allow the use of passwords that never expire, you must renew the password and update the cluster service configuration on each node before password expiration.

  7. Right-click Cluster in the left pane of the Active Directory Users and Computers snap-in. Select Properties from the context menu.

  8. Click Add Members to a Group.

  9. Click Administrators and click OK. This gives the new user account administrative privileges on this computer.

  10. Close the Active Directory Users and Computers snap-in.

Setting Up Shared Disks

Warning: Make sure that Windows 2000 Advanced Server or Windows 2000 Datacenter Server and the Cluster service are installed and running on one node before starting an operating system on another node. If the operating system is started on other nodes before the Cluster service is installed, configured and running on at least one node, the cluster disks will probably be corrupted.

To proceed, power off all nodes. Power up the shared storage devices and then power up node one.

About the Quorum Disk

The quorum disk is used to store cluster configuration database checkpoints and log files that help manage the cluster. We make the following quorum disk recommendations:

  • Create a small partition (min 50MB) to be used as a quorum disk. We generally recommend a quorum disk to be 500MB.)

  • Dedicate a separate disk for a quorum resource. As the failure of the quorum disk would cause the entire cluster to fail, we strongly recommend you use a volume on a RAID disk array.

During the Cluster service installation, you must provide the drive letter for the quorum disk. In our example, we use the letter Q.

Configuring Shared Disks

  1. Right click My Computer, click Manage, and click Storage.

  2. Double-click Disk Management

  3. Verify 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 happens, click Next to go through the wizard. The wizard sets the disk to dynamic. To reset the disk to Basic, right-click Disk # (where # specifies the disk you are working with) and click Revert to Basic Disk.

    Right-click unallocated disk space

    1. Click Create Partition…

    2. The Create Partition Wizard begins. Click Next twice.

    3. Enter the desired partition size in MB and click Next.

    4. Accept the default drive letter assignment by clicking Next.

    5. Click Next to format and create partition.

Assigning Drive Letters

After the bus, disks, and partitions have been configured, drive letters must be assigned to each partition on each clustered disk.

Note: Mountpoints is a feature of the file system that allows you to mount a file system using an existing directory without assigning a drive letter. Mountpoints is not supported on clusters. Any external disk used as a cluster resource must be partitioned using NTFS partitions and must have a drive letter assigned to it.

  1. Right-click the desired partition and select Change Drive Letter and Path.

  2. Select a new drive letter.

  3. Repeat steps 1 and 2 for each shared disk.

    Bb727114.cluste06(en-us,TechNet.10).gif

    Figure 6: Disks with Drive Letters Assigned (drives.bmp)
  4. When finished, the Computer Management window should look like Figure 6 above. Now close the Computer Management window.

Verifying Disk Access and Functionality

  1. Click Start, click Programs, click Accessories, and click Notepad.

  2. Type some words into Notepad and use the File/Save As command to save it as a test file called test.txt. Close Notepad.

  3. Double-click the My Documents icon.

  4. Right-click test.txt and click Copy

  5. Close the window.

  6. Double-click My Computer.

  7. Double-click a shared drive partition.

  8. Click Edit and click Paste.

  9. A copy of the file should now reside on the shared disk.

  10. Double-click test.txt to open it on the shared disk. Close the file.

  11. Highlight the file and press the Del key to delete it from the clustered disk.

Repeat the process for all clustered disks to verify they can be accessed from the first node.

At this time, shut down the first node, power on the second node and repeat the Verifying Disk Access and Functionality steps above. Repeat again for any additional nodes. When you have verified that all nodes can read and write from the disks, turn off all nodes except the first, and continue with this guide.

Install Cluster Service software

Configuring the First Node

Note: During installation of Cluster service on the first node, all other nodes must either be turned off, or stopped prior to Windows 2000 booting. All shared storage devices should be powered up.

In the first phase of installation, all initial cluster configuration information must be supplied so that the cluster can be created. This is accomplished using the Cluster Service Configuration Wizard.

  1. Click Start, click Settings, and click Control Panel.

  2. Double-click Add/Remove Programs.

  3. Double-click Add/Remove Windows Components .

  4. Select Cluster Service. Click Next.

  5. Cluster service files are located on the Windows 2000 Advanced Server or Windows 2000 Datacenter Server CD-ROM. Enter x:\i386 (where x is the drive letter of your CD-ROM). If Windows 2000 was installed from a network, enter the appropriate network path instead. (If the Windows 2000 Setup flashscreen displays, close it.) Click OK.

  6. Click Next.

  7. The window shown in Figure 7 below appears. Click I Understand to accept the condition that Cluster service is supported on hardware from the Hardware Compatibility List only.

    Bb727114.cluste07(en-us,TechNet.10).gif

    Figure 7: Hardware Configuration Certification Screen (hcl.bmp)
  8. Because this is the first node in the cluster, you must create the cluster itself. Select The first node in the cluster, as shown in Figure 8 below and then click Next.

    Bb727114.cluste08(en-us,TechNet.10).gif

    Figure 8: Create New Cluster (clustcreate.bmp)
  9. Enter a name for the cluster (up to 15 characters), and click Next. (In our example, we name the cluster MyCluster.)

  10. Type the user name of the cluster service account that was created during the pre-installation. (In our example, this user name is cluster.) Leave the password blank. Type the domain name, and click Next.

    Note: You would normally provide a secure password for this user account.

    At this point the Cluster Service Configuration Wizard validates the user account and password.

  11. Click Next.

Configuring Cluster Disks

Note: By default, all SCSI disks not residing on the same bus as the system disk will appear in the Managed Disks list. Therefore, if the node has multiple SCSI buses, some disks may be listed that are not to be used as shared storage (for example, an internal SCSI drive.) Such disks should be removed from the Managed Disks list.

  1. The Add or Remove Managed Disks dialog box shown in Figure 9 specifies which disks on the shared SCSI bus will be used by Cluster service. Add or remove disks as necessary and then click Next.

    Bb727114.cluste09(en-us,TechNet.10).gif

    Figure 9: Add or Remove Managed Disks (manageddisks.bmp)

    Note that because logical drives F: and G: exist on a single hard disk, they are seen by Cluster service as a single resource. The first partition of the first disk is selected as the quorum resource by default. Change this to denote the small partition that was created as the quorum disk (in our example, drive Q). Click Next.

    Note: In production clustering scenarios you must use more than one private network for cluster communication to avoid 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. You can also use a public network for cluster management, or you can use a mixed network for both private and public communications. In any case, make sure at least two networks are used for cluster communication, as using a single network for node-to-node communication represents a potential single point of failure. We recommend that multiple networks be used, with at least one network configured as a private link between nodes and other connections through a public network. If you have more than one private network, make sure that each uses a different subnet, as Cluster service recognizes only one network interface per subnet.

    This document is built on the assumption that only two networks are in use. It shows you how to configure these networks as one mixed and one private network.

    The order in which the Cluster Service Configuration Wizard presents these networks may vary. In this example, the public network is presented first.

  2. Click Next in the Configuring Cluster Networks dialog box.

  3. Make sure that the network name and IP address correspond to the network interface for the public network.

  4. Check the box Enable this network for cluster use.

  5. Select the option All communications (mixed network) as shown in Figure 10 below.

  6. Click Next.

    Bb727114.cluste10(en-us,TechNet.10).gif

    Figure 10: Public Network Connection (pubclustnet.bmp)
  7. The next dialog box shown in Figure 11 configures the private network. Make sure that the network name and IP address correspond to the network interface used for the private network.

  8. Check the box Enable this network for cluster use.

  9. Select the option Internal cluster communications only.

    Bb727114.cluste11(en-us,TechNet.10).gif

    Figure 11: Private Network Connection (privclustnet.bmp)
  10. Click Next.

  11. In this example, both networks are configured in such a way that both can be used for internal cluster communication. The next dialog window offers an option to modify the order in which the networks are used. Because Private Cluster Connection represents a direct connection between nodes, it is left at the top of the list. In normal operation this connection will be used for cluster communication. In case of the Private Cluster Connection failure, cluster service will automatically switch to the next network on the list—in this case Public Cluster Connection. Make sure the first connection in the list is the Private Cluster Connection and click Next.

    Important: Always set the order of the connections so that the Private Cluster Connection is first in the list.

  12. Enter the unique cluster IP address (172.16.12.20) and Subnet mask (255.255.252.0), and click Next.

    Bb727114.cluste12(en-us,TechNet.10).gif

    Figure 12: Cluster IP Address (clusterip.bmp)

    The Cluster Service Configuration Wizard shown in Figure 12 automatically associates the cluster IP address with one of the public or mixed networks. It uses the subnet mask to select the correct network.

  13. Click Finish to complete the cluster configuration on the first node.

    The Cluster Service Setup Wizard completes the setup process for the first node by copying the files needed to complete the installation of Cluster service. After the files are copied, the Cluster service registry entries are created, the log files on the quorum resource are created, and the Cluster service is started on the first node.

    A dialog box appears telling you that Cluster service has started successfully.

  14. Click OK.

  15. Close the Add/Remove Programs window.

Validating the Cluster Installation

Use the Cluster Administrator snap-in to validate the Cluster service installation on the first node.

  1. Click Start, click Programs, click Administrative Tools, and click Cluster Administrator.

    Bb727114.cluste13(en-us,TechNet.10).gif

    Figure 13: Cluster Administrator (1nodeadmin.bmp)

    If your snap-in window is similar to that shown above in Figure 13, your Cluster service was successfully installed on the first node. You are now ready to install Cluster service on the second node.

Configuring the Second Node

Note: For this section, leave node one and all shared disks powered on. Power up the second node.

Installing Cluster service on the second node requires 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.

Installation of Cluster service on the second node begins exactly as for the first node. During installation of the second node, the first node must be running.

Follow the same procedures used for installing Cluster service on the first node, with the following differences:

  1. In the Create or Join a Cluster dialog box, select The second or next node in the cluster, and click Next.

  2. Enter the cluster name that was previously created (in this example, MyCluster), and click Next.

  3. Leave Connect to cluster as unchecked. The Cluster Service Configuration Wizard will automatically supply the name of the user account selected during the installation of the first node. Always use the same account used when setting up the first cluster node.

  4. Enter the password for the account (if there is one) and click Next.

  5. At the next dialog box, click Finish to complete configuration.

  6. The Cluster service will start. Click OK.

  7. Close Add/Remove Programs.

If you are installing additional nodes, repeat these steps to install Cluster service on all other nodes.

Verify Installation

There are several ways to verify a successful installation of Cluster service. Here is a simple one:

  1. Click Start, click Programs, click Administrative Tools, and click Cluster Administrator.

    Bb727114.cluste14(en-us,TechNet.10).gif

    Figure 14: Cluster Resources (clustadmin.bmp)

    The presence of two nodes (HQ-RES-DC01 and HQ-RES-DC02 in Figure 14 above) shows that a cluster exists and is in operation.

  2. Right Click the group Disk Group 1 and select the option Move. The group and all its resources will be moved to another node. After a short period of time the Disk F: G: will be brought online on the second node. If you watch the screen, you will see this shift. Close the Cluster Administrator snap-in.

Congratulations. You have completed the installation of Cluster service on all nodes. The server cluster is fully operational. You are now ready to install cluster resources like 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.

This appendix is provided as a generic instruction set for SCSI drive installations. If the SCSI hard disk vendor's instructions conflict with the instructions here, 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. This includes:

  • Configuring the SCSI devices.

  • Configuring the SCSI controllers and hard disks to work properly on a shared SCSI bus.

  • Properly terminating the bus. The shared SCSI bus must have a terminator at each end of the bus. It is possible to have multiple shared SCSI buses between the nodes of a cluster.

In addition to the information on the following pages, refer to the documentation from the manufacturer of the SCSI device or the SCSI specifications, which can be ordered from the American National Standards Institute (ANSI). The ANSI web site contains a catalog that can be searched for the SCSI specifications.

Configuring the SCSI Devices

Each device on the shared SCSI bus must have a unique SCSI ID. Since most SCSI controllers default to SCSI ID 7, part of configuring the shared SCSI bus will be to change the SCSI ID on one controller to a different SCSI ID, such as SCSI ID 6. If there is more than one disk that will be on the shared SCSI bus, each disk must also have a unique SCSI ID.

Some SCSI controllers reset the SCSI bus when they initialize at boot time. If this occurs, the bus reset can interrupt any data transfers between the other node and disks on the shared SCSI bus. Therefore, SCSI bus resets should be disabled if possible.

Terminating the Shared SCSI Bus

Y cables can be connected to devices if the device is at the end of the SCSI bus. A terminator can then be attached to one branch of the Y cable to terminate the SCSI bus. This method of termination requires either disabling or removing any internal terminators the device may have.

Trilink connectors can be connected to certain devices. If the device is at the end of the bus, a trilink connector can be used to terminate the bus. This method of termination requires either disabling or removing any internal terminators the device may have.

Y cables and trilink connectors are the recommended termination methods, because they provide termination even when one node is not online.

Note: Any devices that are not at the end of the shared bus must have their internal termination disabled.
