Module 4: Installing Cluster Service

Overview n Installing Cluster Service n Post-Installation

n 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: n Install Cluster service on one or more servers (single or multinode clusters). n Assign a Cluster service account. n Specify which disks Cluster service will manage. n Assign a location for the cluster file storage. n Configure network adapters for public, private, or mixed cluster communications. n 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.

n 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.

n 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.

n 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. n 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. n 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.

n Note: 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. n The installation steps for the other nodes of the cluster are: 1. Select Joining a cluster. 2. Enter the network basic input/output system (Net. BIOS) name of the cluster to be joined. 3. Enter a Cluster service account password for the new node.

Creating or Joining a Cluster Service Configuration Wizard Create or Join a Cluster You can create a new cluster, or you can join an existing one. 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 Service Configuration Wizard Cluster Name You must name the new cluster. Type a name for the new cluster: CLUSTER 1 < Back Next > Cancel

n 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 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.

u. Create or Join a Cluster n Select The first node in the clusteroption to install the first node of a cluster and create the cluster. You will need to enter a unique network name (Net. BIOS name) for the cluster when you select this option. After you have entered the name, click Next to continue the installation. n Select The second or next nodein the cluster when you are adding nodes to a cluster. You will need to know the Net. BIOS name of the cluster when you select this option.

u. Cluster Name n 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.

Cluster Service Account Cluster Service Configuration Wizard 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 < Back Next > Cancel

n 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.

n In Active Directory™ Users and Computers: 1. Create or assign a service account. 2. Set up password and account options. Select User cannot change passwordand Password never expires.

n 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.

n 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.

Cluster Disks and Cluster File Storage Cluster Service Configuration Wizard 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: Add -> <-Remove Managed disks: Disk 1 M: (sahredscsi) N: (sharedscsi) Cluster Service Configuration Wizard Cluster File Storage You store cluster checkpoint and log files on a cluster disk. These files help manage the cluster. Caution: the likelihood of corruption of unmanaged NTFS disks on. Select a shared a disk buson is which very to store cluster checkpoint and log files. high. It is recommended that you use Cluster service to manage these disks. Select a disk or partition with at least 5 MB of free space (100 MB recommended). It is < Back also recommended that you keep the cluster checkpoint and log files on a separate partition from user applications. Next > Cancel Disks: M: (sharedscsi) N: (sharedscsi) < Back Next > Cancel

n 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.

u. Cluster Disk Selection (Managed Disks) n 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.

n 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. service does not control. n Note: 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.

u. Cluster File Storage n 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.

u. Quorum Disk Recommendations n 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. n 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. n 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.

Configuring Cluster Communications Cluster Service Configuration Wizard 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 FA 310 TX Fast Ethernet Adapter (NGRPCI) IP address: 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) Cluster Service Configuration Wizard Network Connections Type the network name, and specify whether this network will perform as a public, private or mixed network. Network name: < Back Next >Device: Cancel IP address: Public Cluster Connection Realtrek RTL 8029(AS) PCI Ethernet Adapter 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) < Back Next > Cancel

n 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 preinstallation planning. Your choices are public, private, and mixed networks. n 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.

n 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.

u. Network Name n 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.

u. Enable for Cluster Use n 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. n 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.

u. Client access only n 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

u. Internal cluster communications only n 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.

u. All communications or mixed network n 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. n Note: 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.

u. Network Priority n 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. n 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. n When you complete this page, the wizard will finish the installation and start Cluster service

u Post-Installation n Cluster Service Properties n Location of Cluster Files and Folders n Registry Settings n Event Log

n There are many ways to verify that Cluster service has been successfully installed. A simple method is to use the PING protocol to locate the cluster name. Using the PING protocol will verify that Cluster service was started and was able to register the cluster network name.

n In addition, it is recommended that you check to verify whether the following changes have been made to your system: l l Cluster service files and folders are installed in the correct directories. l The new entries have been written to the registry. l n Cluster service is installed. The event log indicates that a successful cluster has been formed. You will need to repeat these verification steps each time that you add a new node to the cluster.
