Safety Instructions

Use the following safety guidelines to help protect your computer system from potential damage and to ensure your own personal safety.

When Using Your Computer System – As you use your computer system, observe the following safety guidelines:

Caution:

Do not operate your computer system with any cover(s) (such as computer covers, bezels, filler brackets, and front-panel inserts) removed:

• To help avoid damaging your computer, be sure the voltage selection

switch on the power supply is set to match the alternating current (AC) power available at your location:

– 115 volts (V)/60 hertz (Hz) in most of North and South America

and some Far Eastern countries such as Japan, South Korea, and Taiwan

– 230 V/50 Hz in most of Europe, the Middle East, and the Far East.

Also be sure your monitor and attached peripherals are electrically rated to operate with the AC power available in your location.

• To help avoid possible damage to the system board, wait 5 seconds

after turning off the system before removing a component from the system board or disconnecting a peripheral device from the computer.

• To help prevent electric shock, plug the computer and peripheral

power cables into properly grounded power sources. These cables are equipped with 3-prong plugs to ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs.

• To help protect your computer system from sudden, transient

increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply.

• Be sure nothing rests on your computer system’s cables and that the

cables are not located where they can be stepped on or tripped over.

• Do not spill food or liquids on your computer. If the computer gets

wet, consult the documentation that came with it.

Preface v

Page 6

• Do not push any objects into the openings of your computer. Doing so

can cause fire or electric shock by shorting out interior components.

• Keep your computer away from radiators and heat sources. Also, do

not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a rug.

When Working Inside Your Computer –

Notice:

1. Turn off your computer and any peripherals.

2. Disconnect your computer and peripherals from their power sources. Also disconnect any telephone or telecommunications lines from the computer.

Doing so reduces the potential for personal injury or shock.

Also note these safety guidelines:

Do not attempt to service the computer system yourself, except as explained in this guide and elsewhere in LSI Logic documentation. Always follow installation and service instructions closely.

• When you disconnect a cable, pull on its connector or on its

strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned.

• Handle components and cards with care. Don’t touch the

components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins.

Protecting Against Electrostatic Discharge – Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface, such as the metal around the card-slot openings at the back of the computer.

vi Preface

Page 7

As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated. In addition to the preceding precautions, you can also take the following steps to prevent damage from electrostatic discharge (ESD):

• When unpacking a static-sensitive component from its shipping

carton, do not remove the component from the antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

• When transporting a sensitive component, first place it in an

antistatic container or packaging.

• Handle all sensitive components in a static-safe area. If possible, use

antistatic floor pads and workbench pads.

Chapter 1 Overview

This section provides a general overview of the MegaRAID 320 series of PCI-to-SCSI Storage Adapters with RAID control capabilities. It consists of the following sections.

• Section 1.1, “Overview”

• Section 1.2, “Features”

• Section 1.3, “Hardware”

1.1 Overview

The MegaRAID 320 Storage Adapters are high-performance intelligent PCI-to-SCSI host adapters with RAID control capabilities. MegaRAID 320 Storage Adapters provide reliability, high performance, and faulttolerant disk subsystem management. They are an ideal RAID solution for the internal storage of workgroup, departmental, and enterprise systems. MegaRAID 320 Storage Adapters offer a cost-effective way to implement RAID in a server.

MegaRAID 320 Storage Adapters are available with one, two, or four SCSI channels. There are two versions of the MegaRAID 320-1 Storage Adapter. The following are descriptions of the adapters:

• The MegaRAID 320-1 Storage Adapter (single-channel) has one

LSI53C1020 controller chip that controls one SCSI channel. The Storage Adapter has one very high-density cable interconnect (VHDCI) 68-pin external SCSI connector and one high-density cable interconnect (HDCI) 68-pin internal SCSI connector.

MegaRAID320 Storage Adapters User’s Guide 1-1

Page 18

• The MegaRAID 320-2 Storage Adapter (dual-channel) has one

LSI53C1030 controller chip that controls two SCSI channels. The Storage Adapter has two VHDCI 68-pin external SCSI connectors and two HDCI 68-pin internal SCSI connectors.

• The MegaRAID 320-2E (Express) Storage Adapter has one 80332

processor that controls two SCSI channels. The Storage Adapter has two UHDCI 68-pin external SCSI connectors and two HDCI 68-pin internal SCSI connectors. Note that the MegaRAID 320-2E is a PCI-Express controller.

• The MegaRAID 320-2X Storage Adapter (dual-channel) has one

LSI53C1030 controller chip that controls two SCSI channels. The Storage Adapter has two VHDCI 68-pin external SCSI connectors and two HDCI 68-pin internal SCSI connectors. Note that the MegaRAID 320-2X is a PCI-X controller.

• The MegaRAID 320-4X Storage Adapter (quad-channel) has two

LSI53C1030 controller chips that control the four SCSI channels. The Storage Adapter has four VHDCI 68-pin external SCSI connectors and two HDCI 68-pin internal SCSI connectors. Note that the MegaRAID 320-4X is a PCI-X controller.

The MegaRAID 320 Storage Adapters support a low-voltage differential (LVD) or a single-ended (SE) SCSI bus. With LVD, you can use cables up to 12 meters long. Throughput on each SCSI channel can be as high as 320 Mbytes/s.

PCI, PCI-X, and PCI-Express are I/O architectures designed to increase data transfers without slowing down the central processing unit (CPU). You can install the MegaRAID 320 PCI and PCI-X Storage Adapters in PCI-X computer systems with a standard bracket type. With these adapters in your system, you can connect SCSI devices over a SCSI bus.

PCI-Express goes beyond the PCI specification in that it is intended as a unifying I/O architecture for various systems: desktops, workstations, mobile, server, communications, and embedded devices.

Note:

For Ultra320 SCSI performance, you must connect only LVD devices to the bus. Do not connect a high voltage differential (HVD) device to the controller. Do not mix SE with LVD devices, or the bus speed will be limited to the slower SE (Ultra SCSI) SCSI data transfer rates.

1-2 Overview

Battery backup is available for the MegaRAID 320-1, 320-2, 320-2E, 320-2X, and 320-4X controllers, either through an onboard battery or daughter card. You can purchase the controller with the battery backup unit (BBU) or purchase the BBU separately.

1.2.4 Drive Roaming

Drive roaming occurs when the hard drives are moved within a configuration on the controller. When the drives are moved, the controller detects the RAID configuration from the configuration information on the drives. Configuration information is saved in both nonvolatile random access memory (NVRAM) on the MegaRAID controller and on the hard drives attached to the controller. This maintains the integrity of the data on each drive, even if the drives have changed their target ID.

Important:

Features 1-5

Before performing drive roaming, make sure to power off

both your platform and your drive enclosure.

Page 22

1.2.5 Drive Migration

Drive migration is the transfer of a set of hard drives in an existing configuration from one controller to a blank controller. The drives must be reinstalled in the same order as in the original configuration.

Important:

Do not perform drive roaming and drive migration at the same time.

1.3 Hardware

You can install the MegaRAID 320-1 and 320-2 boards in a computer with a mainboard that has 5 V or 3.3 V, 32- or 64-bit PCI slots, the MegaRAID 320-2X and -4X in 3.3 V, 64-bit PCI or PCI-X slots, and the MegaRAID 320-2E in 3.3 V PCI-Express slots.

2.3 Detailed Installation

This section provides detailed instructions for installing a MegaRAID 320 Storage Adapter.

Step 1. Unpack the Storage Adapter

Unpack and remove the Storage Adapter. Inspect it for damage. If it appears damaged, or if any items listed below are missing, contact your LSI support representative. The MegaRAID 320 Storage Adapter is shipped with

–the MegaRAID Universal Software Suite CD, which

contains MegaRAID drivers for supported operating systems, an electronic version of this User’s Guide, and other related documentation

– a license agreement

Step 2. Power Down the System

Turn off the computer and remove the AC power cord. Remove the system’s cover. Refer to the system documentation for instructions.

Step 3. Check the jumpers.

Ensure that the jumper settings on the your Storage Adapter are correct. Refer to Chapter 3, “MegaRAID 320 Storage

Adapter Characteristics” for diagrams of the Storage Adapters

with their jumpers and connectors.

Step 4. Install the MegaRAID 320 Storage Adapter

Select a PCI, PCI-X, or PCI-Express slot, and align the Storage Adapter PCI bus connector to the slot. Press down gently but firmly to ensure that the card is properly seated in the slot, as shown in Figure 2.1. Figure 2.2 shows installation of the PCI-Express controller. Then screw the bracket into the computer chassis.

Step 5. Set the Target IDs

Set target identifiers (TIDs) on the SCSI devices. Each device in a channel must have a unique TID. Provide unique TIDs for non-disk devices (CD-ROM or tapes), regardless of the channel where they are connected. The MegaRAID 320 Storage Adapter automatically occupies TID 7, which is the highest priority. The arbitration priority for a SCSI device depends on its TID.

TID 7 6 5 . . . 2 1 0 15 14 . . . 9 8

Step 6. Connect SCSI Devices to the Storage Adapter

Use SCSI cables to connect SCSI devices to the Storage Adapter. Refer to Section 2.4.1, “Internal SCSI Cables” and

Section 2.4.2, “External SCSI Cables” for SCSI cable

information. Refer to Section 2.4.3, “Connecting Internal SCSI

Devices” and Section 2.4.4, “Connecting External SCSI Devices” for details on connecting the controller to internal and

external devices.

To connect the SCSI devices

a. Disable termination on any SCSI device that does not sit at

the end of the SCSI bus.

b. Configure all SCSI devices to supply TERMPWR.

c. Connect cables to the SCSI devices. Refer to the following

table for maximum cable lengths.

Cable Length

SE SCSI 3

Ultra SCSI 1.5

LV D 12

You can connect up to 15 Ultra SCSI devices to each SCSI channel.

in Meters

2-6 Hardware Installation

Page 31

System throughput problems can occur if SCSI cables are not the correct type. To minimize the potential for problems,

– use cables no longer than 12 meters for Ultra160 and

Ultra320 devices (it is better to use shorter cables, if possible)

– use the shortest SCSI cables for SE SCSI devices

(no longer than 3 meters for Fast SCSI, no longer than

1.5 meters for an 8-drive Ultra SCSI system, and no longer than 3 meters for a 6-drive Ultra SCSI system)

– use active termination

– avoid clustering the cable nodes

– note that the cable stub length must be no greater than

0.1 meters (4 inches)

– use high impedance cables

– route SCSI cables carefully.

Step 7. Set SCSI Termination

The SCSI bus is an electrical transmission line and must be terminated properly to minimize reflections and losses. Set termination at each end of the SCSI cable(s).

For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. An easy way to do this is to connect the Storage Adapter to one end of the SCSI cable and to connect an external terminator module at the other end of the cable. You can then connect SCSI disk drives to the connectors between the two ends of the cable. If necessary, disable termination on the SCSI devices. (This is not necessary for Ultra320 and Ultra160 SCSI drives.)

Set the termination so that SCSI termination and TermPWR are intact when any disk drive is removed from a SCSI channel, as shown in Figure 2.3.

Step 8. Power On Host System

Replace the computer cover, and reconnect the AC power cords. Turn power on to the host computer. Ensure that the SCSI devices are powered up at the same time as, or before, the host computer. If the computer is powered up before a SCSI device, the device might not be recognized.

During boot, a BIOS message appears.

The firmware takes several seconds to initialize. During this time, the Storage Adapter scans the SCSI channel(s).

The MegaRAID 320 BIOS Configuration utility prompt times out after several seconds. The second portion of the BIOS message displays the MegaRAID 320 Storage Adapter number, firmware version, and cache SDRAM size. The numbering of the controllers follows the PCI slot scanning order used by the host mainboard.

If you want to run the MegaRAID Configuration utility or the WebBIOS utility at this point, press the appropriate keys when this message appears:

Press <CTRL><M> to run MegaRAID Configuration Utility, or Press <CTRL><H> for WebBIOS

2.4 SCSI Device Cables

For reliable Ultra320 operation, be sure to use an Ultra320-rated SCSI cable. The internal Ultra320 SCSI cable has built-in low voltage differential (LVD) and single-ended termination. This built-in feature is included because most LVD SCSI hard disk drives are not made with on-board low voltage differential termination.

2.4.1 Internal SCSI Cables

You can connect all internal SCSI devices to the Storage Adapter with an unshielded, twisted pair, 68-pin ribbon cable. Some 68-pin internal cables come with a low voltage differential and single-ended terminator on one end, which must be farthest from the host adapter. Figure 2.4 and

Figure 2.5 show internal cables with and without a terminator.

2.5 Replacing a Failed Controller with Data in the TBBU

The MegaRAID Transportable Battery Backup Module (TBBU) is a cache memory module with an integrated battery pack. The module provides an uninterrupted power source to the module if power is unexpectedly interrupted while cached data is still present. If the power failure is the result of the MegaRAID controller itself failing, then the TBBU can be moved to a new controller and the data recovered. The replacement controller must have a cleared configuration.

Perform the following steps to replace a failed controller with data in the transportable battery backup unit.

Step 1. Power-down the system and drives.

Step 2. Remove the failed controller from the system.

Step 3. Remove the TBBU from the failed controller.

Step 4. Insert the TBBU into the replacement controller.

Step 5. Insert the replacement controller into the system.

Step 6. Power-on the system.

The controller then reads the disk configuration into NVRAM and flushes cache data to the logical drives.

Resolving a Configuration Mismatch – If the replacement controller has a previous configuration, a message displays during the power-on self-test (POST) stating that there is a configuration mismatch. A configuration mismatch occurs when the configuration data in the NVRAM and the hard disk drives are different. You need to update the configuration data in the NVRAM with the data from the hard disk drive.

Perform the following steps to resolve the mismatch.

Step 1. Press <Ctrl> <M> when prompted during bootup to access the

BIOS Configuration Utility.

Step 2. Select Configure—>View/Add Configuration.

This gives you the option to view the configuration on both the NVRAM and the hard drive disk.

Step 3. Select the configuration on disk.

Page 40

Step 4. Press <ESC> and select YES to update the NVRAM.

Step 5. Exit and reboot.

2.6 After Installing the Storage Adapter

After Storage Adapter installation, you must configure the Storage Adapter and install the operating system driver. The MegaRAID Configuration Software User’s Guide instructs you on the configuration options and how to set them on your Storage Adapter. The MegaRAID Device Driver Installation User’s Guide provides detailed installation instructions for operating system drivers.

Chapter 3 MegaRAID 320 Storage Adapter Characteristics

This chapter describes the characteristics of the LSI MegaRAID 320 Storage Adapters. This chapter contains the following sections:

• Section 3.1, “MegaRAID 320 Storage Adapter Family”

• Section 3.2, “MegaRAID 320 Storage Adapter Characteristics”

• Section 3.3, “Technical Specifications”

3.1 MegaRAID 320 Storage Adapter Family

PCI is a high-speed standard local bus for interfacing I/O components to the processor and memory subsystems in a high-end PC. The component height on the top and bottom of the Ultra320 SCSI host adapters follows the PCI Local Bus Specification, Revision 2.2, and PCI-X Addendum to the PCI Local Bus Specification, Revision 1.0a. The MegaRAID 320 Storage Adapters are used in PCI-X and PCI computer systems with PCI standard and PCI low-profile bracket types.

The MegaRAID 320-2E controller is used in a system with a PCI-Express slot. PCI-Express goes beyond the PCI specification in that it is intended as a unifying I/O architecture for various systems: desktops, workstations, mobile, server, communications, and embedded devices.

Ta bl e 3 .7 lists the features for the MegaRAID 320 Storage Adapters.

Chapter 4 Installing and Configuring Clusters

This chapter explains how clusters work and how to install and configure them. It contains the following sections:

• Section 4.1, “Overview”

• Section 4.2, “Benefits of Clusters”

• Section 4.3, “Installing and Configuring Your System as Part of a

Cluster”

• Section 4.4, “Driver Installation Instructions under Microsoft Windows

• Section 4.8, “Installing Clusters under Windows Server 2003”

4.1 Overview

A cluster is a grouping of two independent servers that can access the same shared data storage and provide services to a common set of clients (servers connected to common I/O buses and a common network for client access).

2000 Advanced Server”

Note:

The MegaRAID 320-2, -2E, -2X, and -4X Storage Adapters support clustering; the MegaRAID 320-1 does not.

Logically, a cluster is a single management unit. Any server can provide any available service to any authorized client. The servers must have access to the same shared data and must share a common security model. This generally means that the servers in a cluster have the same architecture and run the same version of the operating system.

4.4.1 Network Requirements

The network requirements for clustering are

• A unique NetBIOS cluster name

• Five unique, static IP addresses:

– Two addresses are for the network adapters on the

internal network.

– Two addresses are for the network adapters on the

external network.

– One address is for the cluster itself.

4-4 Installing and Configuring Clusters

Page 63

• 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. HCL certification requires a separate private network adapter.

4.4.2 Shared Disk Requirements

Disks can be shared by the nodes. The requirements for sharing disks are the following:

• All shared disks, including the quorum disk, must be physically

attached to the shared bus.

• All disks attached to the shared bus must be visible from all nodes.

You can check this at the setup level in the BIOS Configuration Utility, which is accessed by pressing <Ctrl> <M> during bootup. Refer to

Section 4.6, “Installing SCSI Drives,” page 4-12, for installation

information.

• Each SCSI device must have a unique SCSI identification number

assigned to it, and each device at the end of the bus must be terminated properly. Refer to the storage enclosure manual for details on installing and terminating SCSI devices.

• Configure all shared disks as basic (not dynamic).

• Format all partitions on the disks as NTFS.

Important:

Use fault-tolerant RAID configurations for all disks. This includes RAID levels 1, 5, 10, and 50.

4.5 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:

After the shared drives are configured, and both nodes powered up, a prompt for another device to be installed appears. This is the peer controller’s initiator ID and is installed as the processor device. The peer processor device for the 320-2 controller is detected as LSI SCSI 320-2. The 320-2X and 320-4X controllers peer processor device are detected as 320-2X SCSI Processor Device and 320-4X SCSI Processor Device.

Perform the following steps to correctly install the driver for this device so that the prompt does not display anymore.

Step 1. Using the MegaRAID SCSI 320-2 controller as an example, in

These steps apply to both Windows 2000 and Windows Server 2003 clusters.

Windows Server 2003, when the peer initiator ID is detected, the New Hardware Wizard detects the peer initiator as LSI SCSI 320-2.

The peer initiator in this example, LSI SCSI 320-2, is shown in

Figure 4.1.

4.6 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. This includes

• Configuring the SCSI devices.

• Configuring the SCSI Storage Adapters 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 next page, refer to the documentation from the SCSI device manufacturer or the SCSI specifications, which can be ordered from the American National Standards Institute (ANSI). The ANSI web site contains a catalog that you can search for the SCSI specifications.

4.6.1 Configuring the SCSI Devices

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

4.6.2 Terminating the Shared SCSI Bus

You can connect Y cables to devices if the device is at the end of the SCSI bus. You can then attach a terminator 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 has.

Important:

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

4-12 Installing and Configuring Clusters

4.7 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.

Ta bl e 4 .1 shows which nodes and storage devices must be powered on

during each step.

Before installing the Cluster Service software, perform the following steps.

Step 1. Install Windows 2000 Advanced Server or Windows 2000

Datacenter Server on each node.

Step 2. Set up networks.

Step 3. Set up disks.

Important:

To configure the Cluster Service on a Windows 2000-based server, you must be able to log on as administrator or have administrative

Installing Clusters under Windows 2000 4-13

Page 72

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. Refer to your Windows 2000 manual for information.

Log on as administrator before you install the Cluster Services.

4.7.2 Setting Up Networks

Important: Do not allow both nodes to access the shared storage

device before the Cluster Service is installed. To prevent this, power down any shared storage devices, then power up nodes one at a time. Install the Clustering Service on at least one node, and ensure it is online before you power up the second node.

Install at least two network card adapters for each cluster node. One network card adapter card is used to access the public network. The second network card adapter is used to access the cluster nodes.

The network card adapter used to access the cluster nodes establishes the following:

• Node-to-node communications

• Cluster status signals

• Cluster Management

Ensure that all the network connections are correct. Network cards that access the public network must be connected to the public network. Network cards that access the cluster nodes must connect to each other.

Verify that all network connections are correct, with private network adapters connected only to other private network adapters, and public network adapters connected only to the public network. View the Network and Dial-up Connections screen in Figure 4.6 to check the connections.

4-14 Installing and Configuring Clusters

Page 73

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. However, if you install Cluster Service on both nodes, and both nodes are powered on, you can add the adapter as a cluster resource and configure it properly for the cluster node network in the Cluster Administrator application.

4.7.3 Configuring the Cluster Node Network Adapter

Note: The wiring determines which network adapter is private and

which is public. For this chapter, the first network adapter (Local Area Connection) is connected to the public network; the second network adapter (Local Area Connection 2) is connected to the private cluster network. This might not be the case in your network.

Installing Clusters under Windows 2000 4-15

Page 74

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

Step 2. Click Rename.

Step 3. In the text box, type:

Private Cluster Connection

and press <Enter>.

Step 4. Repeat steps 1 through 3 to change the name of the public

LAN network adapter to Public Cluster Connection.

These settings should stay the same even if the hardware is different.

Step 17. Select Disable NetBIOS over TCP/IP.

Step 18. Click OK to return to the previous menu. Perform this step for

the private network adapter only.

4.7.5 Configuring the Public Network Adapter

Important: It is strongly recommended that you use static IP

addresses for all network adapters in the cluster. This includes both the network adapter used to access the cluster nodes and the network adapter used to access the LAN (Local Area Network). If you use a dynamic IP address through DHCP, access to the cluster could be terminated and become unavailable if the DHCP server goes down or goes offline.

Installing Clusters under Windows 2000 4-17

Page 76

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.

Page 77

Table 4.2 Example IP Addresses

Node Network Name Network Adapter IP Address

1 Public Cluster Connection 192.168.0.171

1 Private Cluster Connection 10.1.1.1

2 Public Cluster Connection 192.168.0.172

2 Private Cluster Connection 10.1.1.2

In this example, you would type:

Ping 192.168.0.172

and

Ping 10.1.1.1

from Node 1.

Then you would type:

Ping 192.168.0.172

and

10.1.1.1

from Node 2.

To confirm name resolution, ping each node from a client using the node’s machine name instead of its IP number.

4.7.7 Verifying Domain Membership

All nodes in the cluster must be members of the same domain and must be capable of accessing a domain controller and a DNS Server. You can configure them as either member servers or domain controllers. If you configure one node as a domain controller, configure all other nodes as domain controllers in the same domain.

Installing Clusters under Windows 2000 4-19

Page 78

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.

Perform the following steps to set up a cluster user account.

Step 1. Click Start.

Step 2. Point to Programs, then point to Administrative Tools.

Step 3. Click Active Directory Users and Computers.

Step 4. Click the plus sign (+) to expand the domain name (if it is not

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.

To continue, power off all nodes. Power up the shared storage devices. Once the shared storage device is powered up, power up node one.

Quorum Disk – The quorum disk stores cluster configuration database checkpoints and log files that help manage the cluster. Microsoft makes the following quorum disk recommendations:

• Create a small partition. Use a minimum of 50 Mbytes as a quorum

disk. Microsoft generally recommends that a quorum disk be 500 Mbytes.

• Dedicate a separate disk for a quorum resource. The failure of the

quorum disk would cause the entire cluster to fail; therefore, Microsoft strongly recommends that you use a volume on a RAID disk array.

During the Cluster Service installation, you must provide the drive letter for the quorum disk. For our example, we use the letter E.

4.7.10 Configuring Shared Disks

Perform these steps to configure the shared disks:

Step 1. Right-click My Computer.

Step 2. Click Manage, then click Storage.

Step 3. Double-click Disk Management.

Step 10. Accept the default drive letter assignment by clicking Next.

Step 11. Click Next to format and create a partition.

4.7.11 Assigning Drive Letters

After you have configured the bus, disks, and partitions, you must assign drive letters to each partition on each clustered disk. Perform the following steps to assign drive letters.

Important:

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

Mountpoints is a feature of the file system that lets you mount a file system using an existing directory without assigning a drive letter. Mountpoints is not supported on Windows 2000 clusters. Any external disk that is used as a cluster resource must be partitioned using NTFS partitions and must have a drive letter assigned to it.

and Path.

Step 2. Select a new drive letter.

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.

To create the cluster, you must provide the cluster information. The Cluster Configuration Wizard lets you input this information. To use the Wizard, perform these steps:

Step 1. Click Start.

Step 2. Click Settings, then click Control Panel.

Step 3. Double-click Add/Remove Programs.

Step 4. Double-click Add/Remove Windows Components.

Step 5. Select Cluster Service, then click Next.

Step 6. Cluster Service files are located on the Windows 2000

Advanced Server or Windows 2000 Datacenter Server CD-ROM.

Step 7. Enter x:\i386 (where x is the drive letter of your CD-ROM). If

you installed Windows 2000 from a network, enter the appropriate network path instead. (If the Windows 2000 Setup flashscreen displays, close it.)

Step 8. Click OK.

The Cluster Service Configuration Window displays.

Step 9. Click Next.

The Hardware Configuration Certification window appears.

Step 10. Click I Understand to accept the condition that Cluster Service

Page 85

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. You must remove any SCSI disks that are internal to the node and not to be shared storage.

The Add or Remove Managed Disks dialog box (Figure 4.9) specifies disks on the shared SCSI bus that are used by Cluster Service.

Perform the following steps to configure the clustered disks:

Step 1. Add or remove disks as necessary, then click Next.

The Configure Cluster Networks dialog box displays, as shown in Figure 4.10.

The Network Connections dialog box displays, as shown in

Figure 4.11.

4-28 Installing and Configuring Clusters

Page 87

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. In addition, you can use a public network for cluster management, or you can use a mixed network for both private and public communications.

Verify that at least two networks are used for cluster communication. Using a single network for node-to-node communication creates a potential single point of failure. We recommend that you use multiple networks, with at least one network configured as a private link between nodes and other connections through a public network. If you use more than one private network, ensure that each uses a different subnet, as Cluster Service recognizes only one network interface per subnet.

This document assumes that only two networks are in use. It describes how you can configure these networks as one mixed and one private network.

Installing Clusters under Windows 2000 4-29

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. Select Enable This Network for Cluster Use.

Step 5. Select the option All Communications (Mixed Network) and

click Next.

The next dialog box configures the private network, as shown in Figure 4.12. Make sure that the network name and IP address correspond to the network interface used for the private network.

(Private Network), then click Next.

In this example, both networks are configured so that they can be used for internal cluster communication. The next dialog window offers an option to modify the order in which the

Page 89

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).

The Internal Cluster Communication dialog box displays next, as shown in Figure 4.13.

Figure 4.14.

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. It uses the subnet mask to select the correct network.

The final wizard dialog box displays.

Step 10. 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.

Page 92

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.

Installation of Cluster Service on the second node begins the same way as installation on the first node. The first node must be running during installation of the second node.

Follow the same procedures used to install Cluster Service on the first node, with the following differences:

Step 1. In the Create or Join a Cluster dialog box, select The Second

or Next Node in the Cluster, then click Next.

Step 2. Enter the cluster name that was previously created (in this

example, ClusterOne) and click Next.

Step 3. Leave Connect to Cluster as unselected.

The Cluster Service Configuration Wizard automatically supplies the name of the user account selected when you installed the first node. Always use the same account you used when you set up the first cluster node.

Step 4. Enter the password for the account (if there is one), then

click Next.

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

The Cluster Service starts.

Step 6. Click OK.

Step 7. Close Add/Remove Programs.

Step 8. If you install additional nodes, repeat the preceding steps to

install Cluster Service on all other nodes.

This option moves the group and all its resources to another node. Disks F: and G: are brought online on the second node. Watch the screen to see this change.

Page 94

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.

4.8 Installing Clusters under Windows Server 2003

The preparation for the Windows Server 2003 Cluster Service follows the same guidelines as that of the Windows 2000 Cluster Service. The following is assumed to have already been done:

• Installation of the controller and configuration of the controller for

cluster operation. Refer to Procedure to Install and Configure Your system as Part of a cluster in the this chapter.

• The Windows Server 2003 driver for the RAID controller has been

installed. The procedures are similar to those in Section 4.4, “Driver

Installation Instructions under Microsoft Windows 2000 Advanced Server” in this chapter.

• Network requirements have been met.

• Shared disk requirements have been met.

4.8.1 Cluster Service Software Installation

Before you begin the Cluster Service Software installation on the first node, make sure that all other nodes are either powered down or stopped and all shared storage devices are powered on.

4.8.2 Installation Checklist

This checklist helps you prepare for installation. Step-by-step instructions begin after the checklist.

Software Requirements – The following are required for software installation:

4-36 Installing and Configuring Clusters

Page 95

• Microsoft Windows Server 2003 Enterprise Edition or Windows Server

2003 Datacenter Edition installed on all computers in the cluster

• A name resolution method such as Domain Name System (DNS),

DNS dynamic update protocol, Windows Internet Name Service (WINS), HOSTS, and so on

• An existing domain model

• All nodes must be members of the same domain

• A domain-level account that is a member of the local administrators

group on each node. A dedicated account is recommended.

Network Requirements –

• A unique NetBIOS name

• Static IP addresses for all network interfaces on each node

Note:

• Access to a domain controller. If the cluster service is unable to

authenticate the user account used to start the service, it could cause the cluster to fail. It is recommended that you have a domain controller on the same local area network (LAN) as the cluster is on to ensure availability.

• Each node must have at least two network adapters – one for

connection to the client public network and the other for the node-to-node private cluster network. A dedicated private network adapter is required for HCL certification.

• All nodes must have two physically independent LANs or virtual

LANs for public and private communication.

• If you are using fault-tolerant network cards or network adapter

teaming, verify that you are using the most recent firmware and drivers. Check with your network adapter manufacturer for cluster compatibility.

Server Clustering does not support the use of IP addresses assigned from Dynamic Host Configuration Protocol (DHCP) servers.

Installing Clusters under Windows Server 2003 4-37

Page 96

4.8.3 Shared Disk Requirements

• An HCL-approved external disk storage unit connected to all

computers. This is used as the clustered shared disk.

• All shared disks, including the quorum disk, must be physically

attached to a shared bus.

• Shared disks must be on a different controller then the one used by

the system drive.

• Creating multiple logical drives at the hardware level in the RAID

configuration is recommended rather than using a single logical disk that is then divided into multiple partitions at the operating system level. This is different from the configuration commonly used for stand-alone servers. However, it enables you to have multiple disk resources and to do Active/Active configurations and manual load balancing across the nodes in the cluster.

• A dedicated disk with a minimum size of 50 megabytes (MB) to use

as the quorum device. A partition of at least 500 MB is recommended for optimal NTFS file system performance.

• Verify that disks attached to the shared bus can be seen from all

nodes. This can be checked at the host adapter setup level.

• SCSI devices must be assigned unique SCSI identification numbers

and properly terminated.

• All shared disks must be configured as basic disks.

• Software fault tolerance is not natively supported on cluster

shared disks.

• All shared disks must be configured as master boot record (MBR)

disks on systems running the 64-bit versions of Windows Server 2003.

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

• Hardware fault-tolerant RAID configurations are recommended for

all disks.

• A minimum of two logical shared drives is recommended.
