Chapter 1 Automatic Server Failover Introduction This chapter covers the following topics: • Introduction • Summary of the Way it Works • Installing the Failover Hardware Components • Terminology Introduction The automatic server failover mechanism in Avid Interplay allows client access to the Interplay Engine in the event of failures or during maintenance, with minimal impact on the availability. A failover server is activated in the event of application, operating system, or hardware failures.
Chapter 1 Automatic Server Failover Introduction The following diagram illustrates the failover cluster architecture. Two-Node Cluster in Unity MediaNetwork environment Network Switch Interplay clients Private network for heartbeat Interplay Engine - Cluster Node Intranet Cluster shared RAID array Interplay Engine - Cluster Node Fibre Switch n 14 If you are already using clusters, the Avid Interplay Engine won't interfere with your current setup.
Summary of the Way it Works Summary of the Way it Works When the Microsoft® Windows® cluster service is running on the machines and the server is deployed in cluster mode, the Interplay Engine and its accompanying services are exposed to users as a virtual server. To clients, however, connecting to the clustered virtual Interplay Engine appears to be the same process as connecting to a single, physical machine. The user or client application does not know which node is actually hosting the virtual server.
Chapter 1 Automatic Server Failover Introduction Installing the Failover Hardware Components A failover cluster system includes the following components: • Two Interplay Engine nodes or two Interplay Archive nodes (SR2400 servers) • Cluster shared storage - RAID array SR2400 Slot Locations The SR2400 is supported as a server for the Interplay applications. This section describes the slot locations that are specific to the Interplay components in a cluster configuration.

Chapter 1 Automatic Server Failover Introduction Failover Cluster Connections in an Unity MediaNetwork Environment The Interplay Engine Cluster nodes ship with an Intel Pro 1000 MT card in slot 3 (top). You need to move this card to slot 1 (bottom). Then add an ATTO host bus adapter in slot 3 (top).
Terminology Terminology Clustering is not always straightforward, so it is important that you get familiar with the terminology of server clusters before you start. A good source of information is the Microsoft Technology Center for Clustering Services under: http://www.microsoft.com/windowsserver2003/technologies/clustering/default.mspx Detailed architecture documentation can be found here: http://www.microsoft.com/windowsserver2003/techinfo/overview/servercluster.
Chapter 1 Automatic Server Failover Introduction 22
Chapter 2 Automatic Server Failover Installation This chapter describes the processes for configuring the automatic server failover. It is crucial that you follow the instructions given in this chapter completely, otherwise the automatic server failover will not work. You can install the cluster service during any step of the overall Avid Interplay installation process. For the Cluster Group, create a partition on the cluster shared RAID array. This partition is used as the quorum disk (4GB).
Chapter 2 Automatic Server Failover Installation This chapter covers the following topics: • Requirements • Before You Start: Preparation • Configuring the Cluster Service • Configuring Rules For The Cluster Networks • After Setting Up the Cluster • Installing the Distributed Transaction Coordinator • Disabling Any Web Servers • Installing the Interplay Engine on the First Node • Installing Interplay Engine on the Second Node • Bring the MSDTC Services Online • Testing the Complete Ins
Requirements Space Requirements The default disk configuration for the cluster shared RAID array is as follows: • Quorum disk - 4GB • MSDTC disk - 5GB • Database disk - 925GB or larger Antivirus Software You can run antivirus software on a cluster, if the antivirus software is cluster-aware. For information about cluster-aware versions of your antivirus software, contact the antivirus vendor.
Chapter 2 Automatic Server Failover Installation Before You Start: Preparation Before you begin the installation process you need to obtain some IP addresses, IP host names, domain user accounts, and establish server addresses on your network. • Establish the subnet mask, the gateway, DNS and WINS server addresses on your network. • Install and setup Avid Unity client on the Interplay Engine servers. See the Avid Unity MediaNetwork File Manager Setup Guide or the Avid Unity ISIS System Setup Guide.
Before You Start: Preparation List of IP Addresses and Network Names You need to reserve IP host names and static IP addresses before you begin the installation process. A Unity ISIS environment needs 8 IP addresses and a Unity MediaNetwork needs 5 IP addresses. The following table provides a list of example names that you can use when configuring the cluster. The procedures in the chapter use these example names.
Chapter 2 Automatic Server Failover Installation Renaming Local Area Network Interface on Each Node When you rename the LAN interface on each node, make sure you use the same names.

Bring MSDTC DISK R online; right-click MSDTC DISK R and select Bring Online. b.
Disabling Any Web Servers Disabling Any Web Servers n If you followed the procedures in the document no action is required. The Interplay Engine uses an Apache web server that can only be registered as a service if no other web server (for example, IIS) is serving the port 80 (or 443). Stop and disable or uninstall the other http services before you start the installation of the server. You must perform this procedure on both nodes.
Chapter 2 Automatic Server Failover Installation c • Public Network: the name of the public network connection. For example, Left-subnet, Right-subnet, Public. • Shared Drive: S: database • Cluster Service Account User and Password: the domain account that is used to run the cluster. See “Before You Start: Preparation” on page 26. Shut down the second node while installing Interplay Engine for the first time. Starting the Installation and Accepting the License Agreement 1.

Installing the Interplay Engine on the First Node 1. Type the following values: - Virtual IP address: This is the Interplay Engine services IP Address. - Subnet Mask: The subnet mask on the local network. Ask your system administrator for more information on this. - Public Network: The name of the public network connection. For example, Left-subnet, Right-subnet, Public. (the other adapter is used for the cluster heartbeat).
Chapter 2 Automatic Server Failover Installation Specifying the Cluster Details 1. Choose the public names for the Avid Interplay Engine by typing the following values: - The Network Name will be associated with the virtual IP Address that you've entered in the previous Cluster Information dialog. It is registered in the DNS so that clients can find the server without having to specify its address. The name must not exist yet.
Installing the Interplay Engine on the First Node Destination Location The Destination Location is the location of the Interplay Engine program files. 1. Do one of the following: c t Keep the default. t Type another location or use the Browse button to select another location.The installation needs to be on a local disk of the host and not on a shared cluster disk. It is also essential that the same location is used on the other machine.
Chapter 2 Automatic Server Failover Installation Specifying the Default Database Folder The Specify Default Database Folder dialog box opens. The database folder is the place where the database data is stored. 1. Type or browse to the database folder name. This folder should reside on the shared drive that is owned by the resource group of the server.
Installing the Interplay Engine on the First Node Specifying the Share Name The Specify Share Name dialog box opens. The share name is the name to be used by the File Share resource. 1. Type the share name. Avid recommends you use the default sharing name of "WG_Database$". This name is visible on all client platforms, such as Windows 98, Windows ME, Windows NT Windows 2000 and Windows XP. Other sharing names such as "Interplay Database" are only reachable from Windows NT, Windows 2000 and Windows XP.
Chapter 2 Automatic Server Failover Installation Specifying the Configuration Server The Specify Configuration Server dialog box opens. This setting indicates whether this server is to act as a Central Configuration Server. Set for both Interplay Engines Use this option for Interplay Archive A Central Configuration Server (CCS) is an Avid Interplay Engine with a special module which is used to store server and database-spanning information.
Installing the Interplay Engine on the First Node If you do select “Another Avid Interplay Engine,” you need to type the name of the other server to be used as the CCS in the next dialog box. For example, use this option when using an Interplay Archive Engine as the CCS. If you specify the wrong CCS, you can change the setting later on the server machine in the Windows Registry under: HKEY_LOCAL_MACHINE/Software/Avid Technology/Workgroup/DatabaseServer The string value CMS specifies the server.
Chapter 2 Automatic Server Failover Installation 1. Type the Cluster Service Account user login information. The "Server Execution User" is the Windows domain user that runs the Interplay Engine and the cluster service. This user needs to have administrative access to the file server. This user must be the one that was used to set up the cluster service. See “Before You Start: Preparation” on page 26. n The installer cannot check the username or password you type in this dialog.
Installing the Interplay Engine on the First Node Enabling Email Notifications The Enable Email Notification dialog box opens if you are installing the Avid Interplay Engine for the first time. The email notification feature sends emails to your administrator when special events, such as "Cluster Failure", "Disk Full", and "Out Of Memory" occur. Activate email notification if you want to receive emails on special events, server or cluster failures. 1.
Chapter 2 Automatic Server Failover Installation - Type the administrator's email address and the email address of the server, which is the sender. If an event, such as "Resource Failure" "Disk Full" occurs on the server machine, the administrator receives an email from the sender's email account explaining the problem, so that the administrator can react to the problem. You also need to type the static IP address of your SMTP server. The notification feature needs the SMTP server in order to send emails.
Installing the Interplay Engine on the First Node Preparing the Server for the Interplay Engine Installation Using Typical Mode The Typical installation mode, installs the default components of the software. If you have installed the Avid Interplay Engine previously, the settings from the previous installation are used. The Typical installation mode is usually used for upgrading the software.
Chapter 2 Automatic Server Failover Installation 1. Do one of the following: t Select Cluster to continue the installation in cluster mode. t Select Standalone to install a standalone server (on the physical node) without cluster integration. If you select standalone mode, follow the standard installation procedure (see the Avid Interplay Installation Guide: Avid Interplay Engine, Avid Interplay Archive Engine, and Avid Interplay Access). 2. Click Next.
Installing the Interplay Engine on the First Node 1. Type the following values: - Virtual IP address: This is the Interplay Engine services IP Address. - Subnet Mask: The subnet mask on the local network. Ask your system administrator for more information on this. - Public Network: The name of the public network connection. For example, Left-subnet, Right-subnet, Public. (the other adapter is used for the cluster heartbeat).
Chapter 2 Automatic Server Failover Installation Specifying the Server User The Specify Server User dialog box opens. 1. Type the Cluster Service Account user login information. The "Server Execution User" is the Windows domain user that runs the Interplay Engine and the cluster service. This user needs to have administrative access to the file server. This user must be the one that was used to set up the cluster service. See “Before You Start: Preparation” on page 26.
Installing the Interplay Engine on the First Node Beginning the Installation of Interplay Engine on the First Node When all of the settings have been entered, whether you used the Custom mode or Typical mode to prepare the installation, the Ready to Install dialog box opens. 1. Click Next to start the actual installation process of the Interplay Engine, or use Back to revisit the data you have entered.
Chapter 2 Automatic Server Failover Installation 2. Do one of the following: t Click Finish. t Analyze and resolve any issues or failures reported. 3. Click OK if prompted for a restart the system. The installation procedure requires the machine to restart (up to twice). For this reason it is very important that the other node is shut down, otherwise the current node loses ownership of the Avid Workgroup resource group. This applies to the installation on the first node only.
Installing the Interplay Engine on the First Node The Avid Workgroup Disk resource should be online, all other resources offline. 3. Bring the disk resource online manually before continuing if necessary. n Avid does not recommend starting the server at this stage yet, since it is not installed on the other node and a failover would be impossible. 4. (Unity ISIS only) Add IP address on the second subnet for the Interplay Engine. a.
Chapter 2 Automatic Server Failover Installation e. f. Complete TCP/IP Address Parameters dialog box as follows: - Address: type the second Unity ISIS IP address. See “List of IP Addresses and Network Names” on page 27. - Subnet mask: displays subnet for the second subnet network - Network: select a network connection: Right - subnet - Select Enable NetBIOS for this address Click Finish. The following illustration shows the new entry. Avid Workgroup Address 2 g.
Installing Interplay Engine on the Second Node i. Deselect Affect the Group as shown in the following illustration. Affect the group j. Click OK. 5. When the installation is complete, leave this node running so that it maintains ownership of the resource group and proceed to “Installing Interplay Engine on the Second Node” on page 79. Installing Interplay Engine on the Second Node To install Interplay Engine on the second node: 1.
Chapter 2 Automatic Server Failover Installation 3. Click OK. 4. The same installation dialog boxes will open that you saw before, except for the cluster related settings that only has to be entered once. Enter the requested information and allow the installation to proceed. c Make sure you use the installation mode that you used for the first node and enter the same information throughout the installer. Using different values results in a corrupted installation. 5.
Testing the Complete Installation To test the complete installation: 1. To start the server, bring the resource group online; this starts the Interplay Engine and its affiliated services. After starting the Avid Interplay Engine on the first node, the Cluster Administrator should look similar to the following figure. 2. Start an Interplay Administrator, install the licenses if needed, create a test database and add some files to it.
Chapter 2 Automatic Server Failover Installation Updating a Clustered Installation A major benefit of a clustered installation is that you can perform rolling upgrades. You can keep a node in production while updating the installation on the other, then move the resource over and update the second node as well. You are also able to experiment by temporarily keeping two different versions (must be compatible in database format though) on the two nodes if, for example, you want to test a patch.
Uninstalling the Interplay Engine 5. Make sure that first node is online. Update the installation on the first node using the WorkgroupServer.exe installer. Select the Typical mode so that all values are reused. This restarts the first node. 6. During installation, the installer asks you to move the resource groups to the second node. Move the resource groups. Then click OK in the installation dialog box to continue. Restart as requested and continue with Part 2 of the installation.
Chapter 2 Automatic Server Failover Installation 3. When uninstalling a clustered installation, you are asked whether the cluster resources are to be removed. Typically you should select Yes to delete the resources only when uninstalling the second node, otherwise the other installation becomes useless. c 84 The uninstall mechanism of the cluster resources only functions properly if the names of the resources or the resource group were not changed. Never change these names.
Chapter 3 Automatic Server Failover Tips and Rules This chapter provides some important tips and rules to use when configuring the automatic server failover. Don't Access the Machines Directly Don’t access the machines directly. Refer to the projects using the "virtual" network name or IP address that has been assigned to the resource group; never use the actual physical names or IP addresses of the machines that are part of the cluster.
Chapter 3 Automatic Server Failover Tips and Rules Do Not Install the Server on a Shared Disk The Interplay Engine must be installed on the local disk of the cluster nodes and not on a shared resource.
