Instructor Notes

This module is about installing Cluster service The installation is a standard install using the Cluster Configuration Wizard The students need to have an understanding of the choices that they are going to make during the install, such

as where to place the cluster configuration files and assigning the network adapters for cluster communication Students perform post-installation tasks to

verify that Cluster service is properly installed

After completing this module, students will be able to:

Install Cluster service on one or more servers (single or multinode clusters)

Assign a Cluster service account

Specify which disks Cluster service will manage

Assign a location for the cluster file storage

Configure network adapters for public, private, or mixed cluster communications

Verify that Cluster service has been installed as a Microsoft®

Windows® 2000 service, and that the correct changes have been made to the registry, directories, and event log

Module Strategy

Use the following strategy to present this module:

This module follows the steps in the Cluster Service Installation Wizard for installing Cluster service At the end of the module, students need to understand the choices that they will make when they install Cluster service on the job The lab reinforces the installation and verification procedures

Installing Cluster Service

In this section you will step through the installation of Cluster service by using the Cluster Service Configuration Wizard The wizard prompts the user for configuration choices

• Create or Join a Cluster: The wizard first prompts you to either create a new cluster or join an existing one When creating a new cluster, you will typically not use the cluster name for any resources other than cluster administration

• Cluster Service Account: The wizard does not create the Cluster service account, and you must set up the account prior to installing Cluster service

• Shared Disks and Cluster File Storage: The wizard prompts you for disks that the cluster will manage The list of unmanaged disks contains all of the disks that are associated with the node, but are not on the same bus as the operating system After selecting the disks that Cluster service will manage, you need to decide which disk you will use for the cluster configuration files This disk will be the same disk that you will use for the quorum

• Configuring Cluster Communications: When creating a new cluster, you need to decide whether you will use a network card for cluster

communication If you will use a network card for cluster communications, you then decide what type of communications will be performed on that network interface card (NIC): private, public, or mixed

Trang 5

Post-Installation After installing Cluster service, it is a best practice to go through the cluster service properties, files, registry settings and event logs to verify that the installation was successful

• Cluster Service Properties: Cluster service runs as a single service on each node of the cluster You need to check the startup type, the service status, and verify the log on account for the service account on each node

• Location of Cluster Files and Folders: After the installation, it is a best practice to know what files and folders have been added to the node and the shared disks This information can be useful in the restoration of a cluster after a failure

• Registry Settings: The installation of Cluster service adds a cluster hive

to the registry Remind the students that hives are backed up as part of the system state Cluster service replicates the cluster hive to the shared disk and to the other node of the cluster

• Event Log: Depending on whether you are creating or joining a cluster, you will see different results in the event log The event log is also the first place to look if the service was not installed correctly

Instructor Setup for a Lab

Lab A: Installing Cluster Service

To conduct this lab:

Read though the lab carefully, paying close attention to the instructions and details

Students work in teams of two, grouped together by their shared bus

Familiarize the students with the Reference Table and how to find their computers in the table

Make sure that the students understand that they are to begin the lab by installing Cluster service on Node A, and then join Node B to the created cluster

Overview

Installing Cluster Service

Post-Installation

***************************** ILLEGAL FOR NON - TRAINER USE ******************************

After you have completed the pre-installation requirements, you install Microsoft® Cluster service by following the steps in the configuration wizard A successful installation is dependent on having planned in advance You will need the names for the parts of the cluster, a decision about which disks the cluster will manage, where you will locate the quorum disk, and how you will configure the cluster communications

After completing this module, you will be able to:

Install Cluster service on one or more servers (single or multinode clusters)

Assign a Cluster service account

Specify which disks Cluster service will manage

Assign a location for the cluster file storage

Configure network adapters for public, private, or mixed cluster communications

Verify that you have installed Cluster service as a Microsoft Windows® 2000 service, and that the correct changes have been made to the registry, directories, and event log

In this module, you will learn

how to install Microsoft

Windows 2000 Cluster

service and how to verify

that all of the components

are installed correctly

Cluster Service Configuration Wizard

Hardware Configuration

Your hardware configuration must be tested for compatibility with the Cluster service.

< Back Next > Cancel

When you install Microsoft Windows 2000 Advanced Server or Microsoft Windows 2000 Datacenter Server, Microsoft Cluster service is installed as a Windows Component To create a cluster, you run the Cluster Service Configuration Wizard and enter the required information

The installation steps for the first node of the cluster are:

1 Select Create a cluster

2 Assign a cluster name

3 Set up the cluster service account

4 Assign shared disks that the cluster will manage

5 Designate a location for the quorum resource

6 Assign network adapters for specific types of cluster communications

You install Cluster service as a Windows component from Add/Remove

Programs in the Control Panel When you select the option to add Cluster

service, the program starts the Cluster Service Configuration Wizard

The first two pages of the Setup Wizard are the Welcome and Hardware

Configuration pages You do not have to enter any information on the Welcome page, but before you continue you should close any open programs

The Hardware Configuration page contains a warning that Cluster service is

only supported when installed on hardware configurations that have been tested and are on the Cluster service Hardware Compatibility List (HCL) To continue

the setup process, click I Understand to accept the condition that Cluster service is only supported on tested hardware Clicking I Understand enables the Next button

Topic Objective

To introduce the steps for

installing Cluster service by

using the Cluster Service

Configuration Wizard

Lead-in

You install Cluster service

from the Control Panel –

Add/Remove Programs

Remember that Cluster

service has prerequisites,

and you must check the

hardware, software, and

network requirements

before installation

Trang 9

Before you install Cluster service, make sure that you have met all of the

prerequisite requirements Refer to the Job Aid, Pre-installation Checklist, in

the Appendix

The installation steps for the other nodes of the cluster are:

1 Select Joining a cluster

2 Enter the network basic input/output system (NetBIOS) name of the cluster

to be joined

3 Enter a Cluster service account password for the new node

Note

Trang 10

Creating or Joining a Cluster

Create or Join a Cluster

You can create a new cluster, or you can join an existing one.

< Back Next > Next > Cancel

This server is:

The first node in the cluster.

If this server is the first node in a cluster, you are creating a new cluster.

The second or next node in the cluster.

If at least one other node already exists, you are joining an existing cluster.

Cluster Name

You must name the new cluster.

Type a name for the new cluster:

CLUSTER1

The first action that you take in the installation process is to specify whether you are creating a new cluster or adding nodes to an existing one A multinode cluster is installed in two phases First, you install Cluster service on a single server, which will become the first (or only) node in the new cluster You cannot complete the Cluster installation or add additional nodes until you have completed all of the installation requirements that the wizard has requested The second phase is to install any additional nodes that will become part of the cluster

Create or Join a Cluster

Select The first node in the cluster option to install the first node of a cluster

and create the cluster You will need to enter a unique network name (NetBIOS name) for the cluster when you select this option After you have entered the

name, click Next to continue the installation

Select The second or next node in the cluster when you are adding nodes to a

cluster You will need to know the NetBIOS name of the cluster when you select this option

Cluster Name

When you create a cluster, you must assign a cluster name, which you will use for cluster management The name is the first virtual server of the cluster This virtual server is installed by default in a group called Cluster Group When you

have assigned the cluster name, click Next to continue the installation

Topic Objective

To illustrate how to create

the first node and join the

second node in a server

cluster

Lead-in

You can either create or join

a cluster In creating a

cluster, you assign a cluster

name You join a new node

to the cluster by using this

cluster name

Trang 11

Cluster Service Account

Select an Account

For security purposes, the Cluster service must use a domain account.

Type the user name and password for the domain account you want the Cluster service

to use This account is given special security privileges on each cluster node.

User name: clusterservice Password:

Domain: NWTRADERS

The Cluster service account is an account that only the operating system and integrated services use Cluster service requires a Cluster service account to stop and start or take over resources The Cluster service account needs to have administrator rights on each node of the cluster The service account is

responsible for modifying the registry on both cluster nodes

In Active Directory™ Users and Computers:

1 Create or assign a service account

2 Set up password and account options Select User cannot change password and Password never expires

From the Cluster Service Installation Wizard:

1 When prompted by the Cluster Service Installation Wizard, enter the user name, password, and domain name for the user account under which Cluster service will run

2 When you enter the information and click Next, the Setup Wizard validates

the user account and password

The service account must have administrator rights and the log on as a service privilege If it does not, during the installation process, these rights and privileges will be granted to it

Topic Objective

To illustrate how to create

and validate the Cluster

service account

Lead-in

It is recommended that you

create the Cluster service

account prior to installation

The Cluster Service

Configuration Wizard will

assign the appropriate

permissions to the account

Trang 12

Cluster Disks and Cluster File Storage

Add or Remove Managed Disks

The disks that Cluster service controls access to are known as managed disks.

Add the disks that you want the cluster to manage Remove those disks that you do not want the cluster to manage.

Unmanaged disks: Managed disks:

Cluster File Storage

You store cluster checkpoint and log files on a cluster disk These files help manage the cluster.

Select a disk on which to store cluster checkpoint and log files.

Select a disk or partition with at least 5 MB of free space (100 MB recommended) It is also recommended that you keep the cluster checkpoint and log files on a separate partition from user applications.

Disks:

M: (sharedscsi) N: (sharedscsi)

Cluster service uses managed (or shared) disks to enable nodes to access and control shared data and services in case of a node failure You will select a location on one of the managed disks for the storage area where you will store cluster checkpoint and log files These files help manage the cluster

Cluster Disk Selection (Managed Disks)

You will need to identify which disks will be a part of the cluster These managed disks will be available as a resource to Cluster service Designating a disk as a managed disk allows Cluster service to use the small computer system interface (SCSI) reserve and the SCSI release command The SCSI reserve command allows one node to gain access to a disk resource and denies access to other nodes that might try to use a reserved disk The SCSI release command makes that disk resource available so that another node can reserve it

You must specify which disks Cluster service will manage By default, all of the disks on all of the buses other than the system bus will appear in the

Managed disks list Therefore, you need to remove disks if you do not want

Cluster service to manage them

Both servers can access data on any unmanaged disk on the shared bus Data corruption could occur if both servers access data on a shared disk at the same time

Cluster File Storage

At this point of the installation, the Cluster Service Configuration Wizard will prompt you for the location of the Cluster service configuration files (\mscs) The disk that you identify for these files will also be known as the quorum disk After installation, if you change the location of the quorum, Cluster service will move the cluster configuration files to the new disk location

Topic Objective

To illustrate how to specify

which disks Cluster service

will manage and identify a

disk resource where you will

locate cluster files

Lead-in

Identify where you want to

place the quorum disk – the

/mscs directory

Delivery Tip

Cluster service controls

managed disks (cluster

disks) on the shared bus

Unmanaged disks are

shared disks that the Cluster

service does not control

Note

Trang 13

Quorum Disk Recommendations

The partition containing the disk must have a minimum of 50 megabytes (MB) of free space A quorum disk size of 500 MB is generally

recommended

Dedicate a separate disk for a quorum resource so that if failover of a resource or application occurs, the cluster file storage disk will not also fail over

Because the failure of the quorum disk would cause the entire cluster to fail, using a volume on a Redundant Array of Independent Disks (RAID) disk array is highly recommended

Trang 14

Configuring Cluster Communications

Network Connections

Type the network name, and specify whether this network will perform as a public, private or mixed network.

Network name: Private Cluster Connection Device: NETGEAR FA310TX Fast Ethernet Adapter (NGRPCI)

IP address: 100.100.100.1 Enable this network for cluster use This network performs the following role in the cluster:

Client access only (public network) Internal cluster communications only (private network) All communications (mixed network)

Network Connections

Type the network name, and specify whether this network will perform as a public, private or mixed network.

Network name: Public Cluster Connection Device: Realtrek RTL8029(AS) PCI Ethernet Adapter

IP address: 200.200.200.1 Enable this network for cluster use This network performs the following role in the cluster:

Client access only (public network) Internal cluster communications only (private network) All communications (mixed network)

The final step in the installation process is to set up the cluster communications You identified how the nodes will communicate with each other and with clients during pre-installation planning Your choices are public, private, and mixed networks

The Configure Cluster Networks page reminds you that using a single network

for private communications allows for a single point of failure Whenever possible, use more than one network for node-to-node communications and

another network for client-to-node communications Click Next to start the scan

of network adapters

You will need to configure each of the network adapters on each node The

Network Connections page displays the network adapters on the node one at a

time, starting with the first network adapter that is detected For a node with three network adapters, this page will appear three times during Cluster service installation You must enter a network name and select one of the configuration settings for each network adapter

Network Name

The network name is a description that you give to the network adapter and is used as a label to identify the type of network communications to which the adapter is connected For example, if the network adapter is connected to a private network that is used only by the nodes to communicate, the entry for

Network name could be Cluster Net, or Private cluster connection

Topic Objective

To illustrate how to

configure the network

adapters for node-to-node

and client-to-node

communications

Lead-in

Cluster service can run with

one network card, but to

eliminate the network card

as a single point of failure,

two networks are

recommended

Trang 15

Enable for Cluster Use

The Enable the network for cluster use check box is selected by default It

allows Cluster service to use the network adapter Disable this option for an adapter that is used for a dedicated networking task, such as a Web site Cluster service will not be able to use this adapter if this check box is cleared

When you accept the enable default for a network adapter, you will next assign that adapter a communications role according to your cluster communications plan You have three choices

Client access only

You select Client access only to use a network adapter for communication

between the cluster and the clients No node-to-node communication will take

place by means of this network adapter The Client access only option is for

the public network

Internal cluster communications only

You select Internal cluster communications only to use a network adapter for

node-to-node communication No client communication will take place by

means of this network adapter The Internal cluster communication option is

for the private network

All communications or mixed network

You select All communications only to use a network adapter for a mixed

network You will use the adapter for both node-to-node communication and for communication with clients This option is selected by default

If a node only has a single network adapter, a page will appear that recommends that you use multiple network adapters with Cluster service to avoid a single point of failure with one network adapter

Network Priority

When you have configured all of the networks, a new page will prompt you to establish a network priority for private cluster communication networks This list configures the order in which the networks available for private cluster communications fail over in the event of a network failure

The dedicated private network should be at the top of the list of all of the available networks that you can use for private communication This list includes any network that is configured either for private network communications or mixed communications A network that you have configured for public communications will not appear on this list because you cannot use a public network for private cluster communications

When you complete this page, the wizard will finish the installation and start Cluster service
