1Automatic Server Failover Introduction

This chapter covers the following topics:

•Server Failover Overview

•How Server Failover Works

•Installing the Failover Hardware Components

•Clustering Terminology

Server Failover Overview

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. The server can be configured to notify the administrator about such

failures using email.

The Interplay implementation of server failover uses Microsoft® clustering technology. For

background information on clustering technology and links to Microsoft clustering

information, see “Clustering Terminology” on page 39.

cAdditional monitoring of the hardware and software components of a high-availability

solution is always required. Avid delivers Interplay preconfigured, but additional

attention on the customer side is required to prevent outage (for example, when a

private network fails, RAID disk fails, or a power supply loses power). In a mission

critical environment, monitoring tools and tasks are needed to be sure there are no

silent outages. If another (unmonitored) component fails, only an event is generated,

and while this does not interrupt availability, it might go unnoticed and lead to

problems. Additional software reporting such issues to the IT administration lowers

downtime risk.

The failover cluster is a system made up of two server nodes and a shared-storage device

connected over Fibre Channel. These are to be deployed in the same location given the

shared access to the storage device. The cluster uses the concept of virtual servers to specify

groups of resources that failover together.

1 Automatic Server Failover Introduction

The following diagram illustrates the components of a cluster group, including sample IP

addresses. For a list of required IP addresses and node names, see “List of IP Addresses and

Network Names” on page 43.

nIf you are already using clusters, the Avid Interplay Engine will not interfere with your

current setup.

How Server Failover Works

Server failover works on two different levels:

• Failover in case of hardware failure

• Failover in case of network failure

Hardware Failover Process

When the Microsoft cluster service is running on both systems 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, 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.

Server Failover Configurations

When the server is online, the resource monitor regularly checks its availability and

automatically restarts the server or initiates a failover to the other node if a failure is

detected. The exact behavior can be configured using the Windows Cluster Administrator

console. Because clients connect to the virtual network name and IP address, which are also

taken over by the failover node, the impact on the availability of the server is minimal.

Network Failover Process

The cluster resource monitors one primary network that connects the virtual server to the

intranet. If the primary network fails, the virtual server (and thus both cluster nodes) will go

offline. Avid supports a configuration that uses connections to two public networks (VLAN

10 and VLAN 20) on a single switch. However, in this configuration Windows clustering

technology binds multiple virtual IP addresses to VLAN 10 as the primary network, and if

VLAN 10 fails the virtual server will go offline.

For a high degree of protection against network outages, Avid supports a configuration that

uses two network switches, each connected to a shared primary network (VLAN 30) and

protected by a failover protocol. If one network switch fails, the virtual server remains online

through the other VLAN 30 network and switch.

These configurations are described in the next section.

Server Failover Configurations

There are three supported configurations for integrating a failover cluster into an existing

network:

• A cluster in an Avid Unity ISIS environment that is integrated into the intranet through

two layer-3 switches (VLAN 30 in Zone 3). This “redundant-switch” configuration

protects against both hardware and network outages and thus provides a higher level of

protection than the dual-connected configuration.

• A cluster in an Avid Unity ISIS environment that is integrated into the intranet through

two public networks (VLAN 10 and VLAN 20 in Zone 1). This “dual connected”

configuration protects against hardware outages and network outage on VLAN 20 but,

because only VLAN 10 is monitored, does not protect against a outage on the other

network.

• A cluster in an Avid Unity MediaNetwork environment that is integrated into the

intranet through a single public network. This configuration protects against hardware

outages.It relies on a single public network, and so does not protect against a network

outage.

1 Automatic Server Failover Introduction

Redundant-Switch Configuration

The following diagram illustrates the failover cluster architecture for an Avid Unity ISIS

environment that uses two layer-3 switches. These switches are configured for failover

protection through either HSRP (Hot Standby Router Protocol) or VRRP (Virtual Router

Redundancy Protocol). The cluster nodes are connected to two subnets (VLAN 30), each on

a different switch. If one of the VLAN 30 networks fails, the virtual server remains online

through the other VLAN 30 network and switch.

nThis guide does not describe how to configure redundant switches for an Avid Unity ISIS

media network. Configuration information is included in the Avid Unity ISIS Switch

Reference Guide, which is available for download from the Avid Customer Support

Knowledge Base at www.avid.com\onlinesupport.

Dual-Connected Configuration

The following diagram illustrates the failover cluster architecture for an Avid Unity ISIS

environment. In this environment, each cluster node is “dual-connected” to the network

switch: one network interface is connected to the VLAN 10 subnet and the other is

connected to the VLAN 20 subnet. In this configuration Windows clustering technology

binds multiple virtual IP addresses to VLAN 10 as the primary network, and if VLAN 10

fails the virtual server goes offline.

memory, cable, power supply) fails

The cluster detects the outage and triggers failover to the remaining node.

Server Failover Requirements

The following table describes what happens in the MediaNetwork configuration as a result

of an outage:

Server Failover Requirements

You should make sure the server failover system meets the following requirements.

Hardware

A dual-server failover cluster-capable system with an Infortrend® cluster shared-storage

RAID disk set is needed. The automatic server failover system was developed on and tested

with the following:

• Intel Server Chassis SR2500 Packaged Cluster, which is the recommended hardware:

http://www.intel.com/design/servers/chassis/sr2500/

• Intel Server Chassis SR2400 Packaged Cluster:

http://www.intel.com/design/servers/chassis/sr2400/

The servers in a cluster are connected using one or more cluster shared-storage buses and

one or more physically independent networks acting as a heartbeat.

Server Software

Two licenses of Windows Server 2003 Enterprise Edition or Windows Server 2003

Datacenter Edition are needed.

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

Type of Outage Result

Hardware (CPU, network adapter,

memory, cable, power supply) fails

The cluster detects the outage and triggers failover to the remaining node.

The Interplay Engine is still accessible.

Network switch fails The cluster detects the outage and triggers failover but detects that the

second node is also disconnected from the network, and both clusters fail.

The Interplay Engine is not accessible.

1 Automatic Server Failover Introduction

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. If you are running antivirus software on a cluster, make sure you exclude these

locations from the virus scanning: Q:\ (Quorum disk), C:\Windows\Cluster, and

S:\Workgroup_Databases (database).

Functions You Need To Know

Before you set up a cluster in an Avid Interplay environment, you should be familiar with the

following functions:

• Microsoft Windows Active Directory domains and domain users

• Microsoft Windows clustering (current version, as there are changes from prior version)

• Disk configuration (format, partition, naming)

• Network configuration

Installing the Failover Hardware Components

A failover cluster system includes the following components:

• Two Interplay Engine nodes or two Interplay Archive nodes (two SR2400 servers or two

SR2500 servers)

• One Infortrend cluster shared-storage RAID array (one Infortrend A16F-R221 or one

Infortrend A16F-R2431)

1 Automatic Server Failover Introduction

Failover Cluster Connections: Avid Unity MediaNetwork, Infortrend

A16F-R221

Make the following cable connections to add a failover cluster to an Unity MediaNetwork

environment, using the Infortrend A16F-R221RAID array:

• First cluster node:

- Left on-board network interface connector to Ethernet® public network on the Avid

network switch

- QLogic card connector to RAID array, Fibre Channel 1 left connector

- ATTO card connector to Unity MediaNetwork FC switch

• Second cluster node:

- Left on-board network interface connector to Ethernet public network on the Avid

network switch

- QLogic card connector to RAID array, Fibre Channel 0 left connector

- ATTO card connector to Unity MediaNetwork FC switch

• Right on-board network interface connector on the first cluster node to right on-board

network interface connector on the second cluster node (private network for heartbeat)

• All switches on the cluster shared-storage RAID array are in the default “enable”

position (left)

nSR2400 servers 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). See “SR2400 Slot

Locations” on page 21.

You can implement this configuration using either SR2400 servers or SR2500 servers. The

following illustrations show the connections for each type of server.

Clustering 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.mspx

Here is a brief summary of the major concepts and terms:

•Nodes: Individual computers in a cluster configuration.

•Cluster service: The group of components on each node that perform a cluster-specific

activity.

•Resource: Cluster components (hardware and software) that are managed by the cluster

service. Resources are physical hardware devices such as disk drives, and logical items

such as IP addresses and applications.

•Online resource: A resource that is available and is providing its service.

•Quorum resource: A special common cluster resource. This resource plays a critical role

in cluster operations.

•Resource group: A collection of resources that are managed by the cluster service as a

single, logical unit.

1 Automatic Server Failover Introduction

2 Creating a Microsoft Failover Cluster

This chapter describes the processes for creating a Microsoft failover cluster for automatic

server failover. It is crucial that you follow the instructions given in this chapter completely,

otherwise the automatic server failover will not work.

This chapter covers the following topics:

•Server Failover Installation Overview

•Before You Begin the Server Failover Installation

•Preparing the Server for the Cluster Service

•Configuring the Cluster Service

•Configuring Rules for the Cluster Networks

•After Setting Up the Cluster

•Installing the Distributed Transaction Coordinator

Instructions for installing the Interplay Engine are provided in “Installing the Interplay

Engine for a Failover Cluster” on page 83.

Server Failover Installation Overview

Installation and configuration of the automatic server failover consists of the following

major tasks:

• Make sure that the network is correctly set up and that you have reserved IP host names

and static IP addresses (see “Before You Begin the Server Failover Installation” on page

42).

• Prepare the servers for the cluster service (see “Preparing the Server for the Cluster

Service” on page 47). This includes configuring the nodes for the network and

formatting the drives.

• Configure the cluster service (see “Configuring the Cluster Service” on page 61,

“Configuring Rules for the Cluster Networks” on page 70, and “After Setting Up the

Cluster” on page 72).

• Install the Distributed Transaction Coordinator (MSDTC group) (see “Installing the

Distributed Transaction Coordinator” on page 76).

2 Creating a Microsoft Failover Cluster

• Install the Interplay Engine on both nodes (see “Installing the Interplay Engine for a

Failover Cluster” on page 83).

• Test the complete installation (see “Testing the Complete Installation” on page 104).

nDo not install any other software on the cluster machines except the Interplay engine. For

example, Media Indexer software needs to be installed on a different server. For complete

installation instructions, see the Avid Interplay Software Installation and Configuration

Guide.

For more details about server clusters, see the Microsoft document “Guide to Creating and

Configuring a Server Cluster under Windows Server 2003,” available at:

http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/clustering

/confclus.mspx

Before You Begin the Server Failover Installation

Before you begin the installation process, you need to do the following:

• Make sure all cluster hardware connections are correct. See “Installing the Failover

Hardware Components” on page 20.

• Make sure that the facility has a network that is qualified to run Active Directory and

DNS services.

• Determine the subnet mask, the gateway, DNS, and WINS server addresses on the

network.

• Install and set up an Avid Unity client on both servers. See the Avid Unity

MediaNetwork File Manager Setup Guide or the Avid Unity ISIS System Setup Guide.

• Create or select two domain user accounts:

- Cluster Service Account (Server Execution User): Create or select an account

(sometimes called the cluster user account) that is used to start the cluster service

and is also used by the Interplay Engine service. This account must be a domain

user and it must be a unique name that will not be used for any other purpose. The

procedures in this document use sqauser as an example of a Cluster Service

Account. This account is automatically added to the Local Administrators group on

each node by the Interplay Engine software during the installation process.

The Server Execution User is critical to the operation of the Interplay Engine. If

necessary, you can change the name of the Server Execution User after the

installation. For more information, see “Troubleshooting the Server Execution User

Account” and “Re-creating the Server Execution User” in the Avid Interplay Engine

and Avid Interplay Archive Engine Administration Guide and the Interplay ReadMe.

Before You Begin the Server Failover Installation

For information on creating a cluster user account, see the Microsoft document

“Guide to Creating and Configuring a Server Cluster under Windows Server 2003.”

http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/cl

ustering/confclus.mspx.

- Cluster Installation and Administration Account: Create or select a user account to

use during the installation process. This user account must be a domain user

account with privileges to add servers to the domain. Also use this account to log in

to and administer the system.

nDo not use the same username and password for the Cluster Service Account and the

Cluster Installation Account. These accounts have different functions and require different

privileges.

• Create an Avid Unity user account with read and write privileges. This account is not

needed for the installation of Interplay Engine, but is required for the operation of

Interplay Engine. The user name and password must match the user name and password

of the Cluster Service Account.

• Make sure the network includes an Active Directory domain before you install or

configure the cluster.

• Reserve static IP addresses for all network interfaces and host names. See “List of IP

Addresses and Network Names” on page 43.

List of IP Addresses and Network Names

You need to reserve IP host names and static IP addresses on the in-network DNS server

before you begin the installation process. The number of IP addresses you need depends on

your configuration:

• An Avid Unity ISIS environment with a redundant-switch configuration requires 5 IP

addresses

• An Avid Unity ISIS environment with a dual-connected configuration requires 8 IP

addresses

• An Avid Unity MediaNetwork environment requires 5 IP addresses.

The following table provides a list of example names that you can use when configuring the

cluster. The procedures in this chapter use these example names.

nMake sure that these IP addresses are outside of the range that is available to DHCP so they

cannot automatically be assigned to other machines.

2 Creating a Microsoft Failover Cluster

nIf your Active Directory domain or DNS includes more than one cluster, to avoid conflicts,

you need to make sure the cluster names, MSDTC names, and IP addresses are different for

each cluster.

nAll names must be valid and unique network host names.

Preparing the Server for the Cluster Service

Before you configure the cluster service, you need to complete the tasks in the following

procedures:

•“Setting the QLogic HBA Link Speed” on page 47

•“Increasing the Boot Delay” on page 49

•“Setting the ATTO Link Speed” on page 50

•“Renaming the Local Area Network Interface on Each Node” on page 52

•“Removing Unnecessary Windows Components” on page 51

•“Renaming the Local Area Network Interface on Each Node” on page 52

•“Configuring the Private Network Adapter on Each Node” on page 55

•“Configuring the Binding Order Networks on Each Node” on page 58

•“Configuring the Public Network Adapter on Each Node” on page 60

•“Joining Both Servers to the Active Directory Domain” on page 60

•“Configuring the Cluster Shared-Storage RAID Disks on Each Node” on page 60

Setting the QLogic HBA Link Speed

To avoid possible problems with the Infortrend RAID array (Model A16F-R221), Avid

recommends that you change the QLogic HBA link speed (data rate) from the default setting

to 2 Gbps. You need to specify this setting on both the SR2400 server and the SR2500

server. Change the setting by using the SAN Surfer utility on both nodes.

To set the QLogic HBA link speed:

1. On the first node, click Start, and select Programs > QLogic Management Suite > San

Surfer.

The San Surfer FC HBA Manager dialog box opens.

2 Creating a Microsoft Failover Cluster

2. In the left pane, select Port 1.

3. Click the Settings tab.

4. In the HBA Port Settings section, click the arrow pointer for the Data Rate list and

change the default setting from Auto to 2 Gbps.

5. Click Save.

6. When prompted for a password, enter

config

and click OK.

7. On the other node, repeat steps 1 through 6.

8. Verify that the SAN Surfer data rate is set to 2 Gbps on both nodes.

Preparing the Server for the Cluster Service

Increasing the Boot Delay

Increasing the the timeout value in the boot.ini file increases the time it takes for the server

to boot. This boot delay might avoid a problem if the Infortrend requires a longer than usual

time for a self-test and initializing. If a server boots before the Infortrend is ready, the cluster

might fail.

Avid recommends that you offset the startup time of each node’s operating system (see

“Setting the Startup Times on Each Node” on page 73).

To increase the timeout value in the boot.ini file:

1. Start the first node and log in to Windows.

2. At the command prompt, type the following command and press Enter:

bootcfg /timeout 60

This command changes the boot timeout delay to 60 seconds, after which the default

operating system is loaded.

3. Repeat these steps on the second node, but set the timeout delay to 120 seconds.

2 Creating a Microsoft Failover Cluster

Setting the ATTO Link Speed

To avoid possible problems with the Infortrend RAID array (Model A16F-R2431), Avid

recommends that you change the ATTO link speed (data rate) from the default setting to 4

Gbps. You need to specify this setting on both the SR2400 server and the SR2500 server.

Change the setting by using the ATTO Configuration Tool on both nodes.

To set the ATTO link speed:

1. On the first node, click Start, and select Programs > ATTO Configuration Tool >

Configuration Tool.

The ATTO Configuration Tool dialog box opens.

2. In the left pane, navigate to the appropriate channel on your host adapter.

The NVRAM tab opens.

3. Click the arrow pointer for the Data Rate list and change the default setting from Auto to

4 Gb/sec.

Preparing the Server for the Cluster Service

4. Click Commit.

5. Reboot the system.

6. Open the Configuration tool again and verify that the Data Rate is set to 4 Gb/sec.

7. On the other node, repeat steps 1 through 6.

Removing Unnecessary Windows Components

You need to remove some unnecessary Windows components before you configure the

cluster service. Which components you remove depends on the type of cluster you are

configuring.

• For a cluster that will be used as an Interplay Engine, remove the following from each

server:

- Internet Information Services (IIS)

- IIS-Admin

- Internet Explorer Enhanced Security Configuration

- Microsoft SQL Native Client

• For a cluster that will be used as an Interplay Archive Engine, remove the following

from each server:

- Internet Information Services (IIS)

- IIS-Admin

- Internet Explorer Enhanced Security Configuration

nMicrosoft SQL Native Client is required for SGL archive solutions and should be correctly

installed and configured before creating a cluster that will be used as an Archive Engine.

To remove unnecessary Windows components:

1. On one of the servers, click Start and select Control Panel > Add or Remove Programs.

2. (Interplay Engine only) If Microsoft SQL Native Client is listed, select it and click

Change/Remove.

2 Creating a Microsoft Failover Cluster

3. Click Add/Remove Windows Components.

a. If a box is checked for Internet Explorer Enhanced Security Configuration, click the

check box to remove the check.

b. Select Application Server and click Details.

c. If a box is checked for Internet Information Services (IIS), click the check to

remove the check.

d. Click OK, then click Next. At the end of the process, click Finish.

4. Repeat the procedure on the other server.

Renaming the Local Area Network Interface on Each Node

You need to rename the LAN interface on each node to appropriately identify each network.

Although you can use any name for the network connections, Avid suggests that you use the

naming conventions provided in the table in the following procedure.

Make sure you use the same name on both nodes. The names and network connections on

both nodes must match.

To rename the local area network connections:

1. Open the Network Connections window.

a. Click Start and select Control Panel.

b. Right-click Network Connections, and select Open.

The Network Connections window opens.

Preparing the Server for the Cluster Service

2. Right-click one of the listed network connections and select Rename.

You need to match the numbered connection with the appropriate device. For example,

you can start by determining which connection refers to the left on-board network

interface and select that connection.

cBoth nodes must use identical network interface names. Although you can use any

name for the network connections, Avid suggests that you use the naming conventions

provided in the following table.

3. Depending on your Avid Unity network and the device you selected, type a new name

for the network connection and press Enter.

Use the following illustration and table for reference. The illustration uses an SR2400 in

an Avid Unity ISIS environment as an example.

- Local Area Connection 4

2 Creating a Microsoft Failover Cluster

- For an Avid Unity MediaNetwork environment use the following order:

-Public

-Private

4. Click OK.

5. Repeat this procedure on the other node and make sure the configuration matches on

both nodes.

Configuring the Public Network Adapter on Each Node

Make sure you configure the IP address network interfaces for the Public Network Adapter

as you normally would. For examples of public network settings, see “List of IP Addresses

and Network Names” on page 43.

Joining Both Servers to the Active Directory Domain

After configuring the network information, join the two servers to the Active Directory

domain. You can then use your domain credentials for the Cluster Installation Account (see

“Before You Begin the Server Failover Installation” on page 42).

Configuring the Cluster Shared-Storage RAID Disks on Each Node

Both nodes must have the same configuration for the cluster shared-storage RAID disk.

When you configure the disks on the second node, make sure the disks match the disk

configuration you set up on the first node.

nBefore you create the partitions on the cluster nodes, make sure the cluster shared-storage

RAID disks were pre-configured (mirror, stripe, etc.) by the vendor. Make sure the disks are

Basic and not Dynamic.

To configure the disks on each node:

1. Shut down the server node you are not configuring at this time.

2. Open the Disk Management tool.

3Installing the Interplay Engine for a

Failover Cluster

After you set up and configure the cluster, you need to install the Interplay Engine software

on both nodes. The following topics describe installing the Interplay Engine and other final

tasks:

•Disabling Any Web Servers

•Installing the Interplay Engine on the First Node

•Installing the Interplay Engine on the Second Node

•Bringing the Interplay Engine Online

•Testing the Complete Installation

•Updating a Clustered Installation (Rolling Upgrade)

•Uninstalling the Interplay Engine on a Clustered System

Disabling Any Web Servers

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 any other http services before you start the installation of the server. You must

perform this procedure on both nodes.

nIf you followed the procedures in this document no action is required, since the only web

server installed at this point is the IIS and it is disabled.

3 Installing the Interplay Engine for a Failover Cluster

Installing the Interplay Engine on the First Node

The following sections provide procedures for installing the Interplay Engine on the first

node. For a list of example entries, see “List of IP Addresses and Network Names” on page

43.

•“Preparation for Installing on the First Node” on page 84

•“Starting the Installation and Accepting the License Agreement” on page 85

•“Installing the Interplay Engine Using Custom Mode” on page 85

•“Bringing the Disk Resource Online” on page 99

cShut down the second node while installing Interplay Engine for the first time.

Preparation for Installing on the First Node

You are ready to start installing the Interplay Engine on the first node. During setup you

must enter the following cluster-related information:

• Virtual IP Address: the Interplay Engine service IP address of the resource group. For a

list of example names, see “List of IP Addresses and Network Names” on page 43.

• Subnet Mask: the subnet mask on the local network.

• Public Network: the name of the public network connection.

- For a redundant-switch ISIS configuration, type Public.

- For a dual-connection ISIS configuration, type Left-subnet. For a dual-connection

configuration, you set the other public network connection after the installation. See

“Bringing the Disk Resource Online” on page 99.

- For a MediaNetwork configuration, type Public.

To check the public network connection on the first node, open the Network

Connections panel in the Windows Control Panel and look up the name there.

• Shared Drive: the letter for the shared drive that holds the database. Use S: for the

shared drive letter.

• Cluster Service Account User and Password (Server Execution User): the domain

account that is used to run the cluster. See “Before You Begin the Server Failover

Installation” on page 42.

cShut down the second node while installing Interplay Engine for the first time.

Installing the Interplay Engine on the First Node

nWhen installing the Interplay Engine for the first time on a machine with cluster services,

you are asked to choose between clustered and regular installation. The installation on the

second node (or later updates) reuses the configuration from the first installation without

allowing you to change the cluster-specific settings. In other words, it is not possible to

change the configuration settings without uninstalling the Interplay Engine.

Starting the Installation and Accepting the License Agreement

To start the installation:

1. Insert the Avid Interplay installation DVD.

A start screen opens.

2. Double-click Install Avid Interplay Engine to begin the Avid Interplay Engine

selecting “I accept the agreement.” Click Next.

The Specify Installation Type dialog box opens.

6. Continue the installation as described in the next topic.

Installing the Interplay Engine Using Custom Mode

The first time you install the Interplay Engine on a cluster system, you should use the

Custom installation mode. This lets you specify all the available options for the installation.

This is the recommended option to use.

The following procedures are used to perform a Custom installation of the Interplay Engine:

•“Specifying Cluster Mode During a Custom Installation” on page 86

•“Specifying the Interplay Engine Details” on page 87

•“Specifying the Interplay Engine Service Name” on page 89

•“Specifying the Destination Location” on page 90

•“Specifying the Default Database Folder” on page 90

The Specify Interplay Engine Details dialog box opens.

Specifying the Interplay Engine Details

In this dialog box, provide details about the Interplay Engine.

3 Installing the Interplay Engine for a Failover Cluster

To specify the Interplay Engine details:

1. Type the following values:

- Virtual IP address: This is the Interplay Engine service IP Address, not the Cluster

service IP address. For a list of example names, see “List of IP Addresses and

Network Names” on page 43.

- Subnet Mask: The subnet mask on the local network.

- Public Network: For a redundant-switch ISIS configuration or MediaNetwork

configuration, type Public. For a dual-connected ISIS configuration, type

Left-subnet. For a dual-connected configuration, you set the other public network

connection after the installation. See “Bringing the Disk Resource Online” on page

99. For MediaNetwork, type Public.

To check the public network connection on the first node, open the Network

Connections panel in the Windows Control Panel and look up the name there.

- Shared Drive: The letter of the shared drive that is used to store the database. Use S:

for the shared drive letter.

cMake sure you type the correct information here, as this data cannot be changed

afterwards. Should you require any changes to the above values later, you will need to

uninstall the server on both nodes.

2. Click Next.

Installing the Interplay Engine on the First Node

The Specify Interplay Engine Name dialog box opens.

Specifying the Interplay Engine Service Name

In this dialog box, type the name of the Interplay Engine service.

To specify the Interplay Engine name:

1. Specify the public names for the Avid Interplay Engine service by typing the following

values:

- The Network Name will be associated with the virtual IP Address that you entered

in the previous Interplay Engine Details dialog box. This is the Interplay Engine

service name (see “List of IP Addresses and Network Names” on page 43). It must

be a new, unused name, and must be registered in the DNS so that clients can find

the server without having to specify its address.

- The Server Name is used by clients to identify the server. If you only use Avid

Interplay Clients on Windows computers, you can use the Network Name as the

server name. If you use several platforms as client systems, such as Macintosh® and

Linux® you need to specify the static IP address that you entered for the resource

group in the previous dialog box. Macintosh systems are not always able to map

server names to IP addresses. If you type a static IP address, make sure this IP

address is not provided by a DHCP server.

2. Click Next.

3 Installing the Interplay Engine for a Failover Cluster

The Specify Destination Location dialog box opens.

Specifying the Destination Location

In this dialog box specify the folder in which you want to install the Interplay Engine

program files.

To specify the destination location:

1. Avid recommends that you keep the default path C:\Program Files\Avid\Avid Interplay

Engine.

cUnder no circumstances attempt to install to a shared disk; independent installations

are required on both nodes. This is because local changes are also necessary on both

machines. Also, with independent installations you can use a rolling upgrade approach

later, upgrading each node individually without affecting the operation of the cluster.

2. Click Next.

The Specify Default Database Folder dialog box opens.

Specifying the Default Database Folder

In this dialog box specify the folder where the database data is stored.

Installing the Interplay Engine on the First Node

To specify the default database folder:

1. Type S:\Workgroup_Databases. Make sure the path specifies the shared drive (S:).

This folder should reside on the shared drive that is owned by the resource group of the

server. Avid strongly recommends using the shared drive resource so that it can be

monitored and managed by the cluster service. The drive must be assigned to the

physical drive resource that is mounted under the same drive letter on the other machine.

2. Click Next.

The Specify Share Name dialog box opens.

Specifying the Share Name

In this dialog box specify a share name to be used for the database folder.

3 Installing the Interplay Engine for a Failover Cluster

To specify the share name:

1. Accept the default share name.

Avid recommends you use the default share name WG_Database$. This name is visible

on all client platforms, such as Windows 98, Windows ME, Windows NT Windows

2000 and Windows XP.The “$” at the end makes the share invisible if you browse

through the network with the Windows Explorer. For security reasons, Avid

recommends using a “$” at the end of the share name. If you use the default settings, the

directory S:\Workgroup_Databases is accessible as \\InterplayEngine\WG_Database$.

2. Click Next.

This step takes a few minutes. When finished the Specify Configuration Server dialog

box opens.

Specifying the Configuration Server

In this dialog box, indicate whether this server is to act as a Central Configuration Server.

Installing the Interplay Engine on the First Node

A Central Configuration Server (CCS) is an Avid Interplay Engine with a special module

that is used to store server and database-spanning information. For more information, see the

Avid Interplay Engine and Avid Interplay Archive Engine Administration Guide.

To specify the server to act as the CCS server:

1. Select either the server you are installing or a previously installed server to act as the

Central Configuration Server.

Typically you are working with only one server, so the appropriate choice is “This Avid

Interplay Engine,” which is the default.

If you need to specify a different server as the CCS (for example, if an Interplay Archive

Engine is being used as the CCS), 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.

cOnly use a CCS that is at least as high availability as this cluster installation, typically

another clustered installation.

If you specify the wrong CCS, you can change the setting later on the server machine in

the Windows Registry. See “Automatic Server Failover Tips and Rules” on page 109.

2. Click Next.

The Specify Server User dialog box opens.

Set for both nodes.

Use this option for

Interplay Archive

Engine

3 Installing the Interplay Engine for a Failover Cluster

Specifying the Server User

In this dialog box, define the Cluster Service account (Server Execution User) used to run

the Avid Interplay Engine.

The Server Execution User is the Windows domain user that runs the Interplay Engine and

the cluster service. This account is automatically added to the Local Administrators group

on the server. This account must be the one that was used to set up the cluster service. See

“Before You Begin the Server Failover Installation” on page 42.

To specify the Server Execution User:

1. Type the Cluster Service Account user login information.

cThe installer cannot check the username or password you type in this dialog. Make

sure that the password is set correctly, or else you will need to uninstall the server and

repeat the entire installation procedure. Avid does not recommend changing the Server

Execution User in cluster mode afterwards, so choose carefully.

cWhen typing the domain name do not use the full DNS name such as

mydomain.company.com, because the DCOM part of the server will be unable to start.

You should use the NetBIOS name, for example, mydomain.

2. Click Next.

The Specify Preview Server Cache dialog box opens.

Installing the Interplay Engine on the First Node

If necessary, you can change the name of the Server Execution User after the installation.

For more information, see “Troubleshooting the Server Execution User Account” and

“Re-creating the Server Execution User” in the Avid Interplay Engine and Avid Interplay

Archive Engine Administration Guide and the Interplay ReadMe.

Specifying the Server Cache

In this dialog box, specify the path for the cache folder.

nFor more information on the Preview Server cache and Preview Server configuration, see

“Avid Workgroup Preview Server Service” in the Avid Interplay Engine and Avid Interplay

Archive Engine Administration Guide.

To specify the server cache folder:

1. Type or browse to the path of the server cache folder. Typically, the default path is used.

2. Click Next.

The Enable Email Notification dialog box opens if you are installing the Avid Interplay

Engine for the first time.

Enabling Email Notifications

The first time you install the Avid Interplay Engine, the Enable Email Notification dialog

box opens. 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.

To enable email notification:

1. (Option) Select Enable email notification on server events.

The Email Notification Details dialog box opens.

Installing the Interplay Engine on the First Node

2. Type the administrator's email address and the email address of the server, which is the

sender.

If an event, such as “Resource Failure” or “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. If you do not know this IP, ask your administrator.

3. If you also want to inform Avid Support automatically using email if problems arise,

select “Send critical notifications also to Avid Support.”

4. Click Next.

The installer modifies the file Config.xml in the Workgroup_Data\Server\Config\Config

directory with your settings.

The Ready to Install dialog box opens.

3 Installing the Interplay Engine for a Failover Cluster

Installing the Interplay Engine for a Custom Installation on the First Node

In this dialog box, begin the installation of the engine software.

To install the Interplay Engine software:

1. Click Next.

Use the Back button to review or change the data you have entered. You can also

terminate the installer using the Cancel button, because no changes have been done to

the system yet.

The first time you install the software, a dialog box opens and asks if you want to install

the Sentinel driver. This driver is used by the licensing system.

2. Click Continue.

The Installation Completed dialog box opens after the installation is completed.

3. Do one of the following:

tClick Finish.

tAnalyze and resolve any issues or failures reported.

4. 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.

nSubsequent installations should be run as described in “Updating a Clustered Installation

(Rolling Upgrade)” on page 106 or in the Avid Interplay ReadMe.

Bringing the Disk Resource Online

To bring the Disk Resource online:

1. After the installation is complete, start the Cluster Administrator tool by clicking Start

and selecting Programs > Administrative Tools > Cluster Administrator.

2. Open the Avid Workgroup Server resource group.

The list of resources should look similar to those in the following illustration.

3 Installing the Interplay Engine for a Failover Cluster

100

The Avid Workgroup Disk resource should be online and all other resources offline.

3. Bring the disk resource online manually before continuing if necessary.

nAvid 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. (Avid Unity ISIS dual-connected configuration only) Add the IP address on the

second subnet for the Interplay Engine.

a. In the Cluster Administrator, right-click Avid Workgroup Server and select New >

Resource.

b. Complete the New Resource dialog box as follows:

- Name: Avid Workgroup Address 2

- Resource Type: IP Address

- Group: Avid Workgroup Server

c. Complete the Possible Owners dialog box as follows:

- Add the cluster server host names to the Possible owners lists. For example,

SECLUSTER1 and SECLUSTER2. See “List of IP Addresses and Network

Names” on page 43.

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 the Interplay Engine on the Second

Node” on page 102.

Installing the Interplay Engine on the Second Node

To install the Interplay Engine on the second node:

1. Leave the first machine running so that it maintains ownership of the resource group and

start the second node.

cDo not attempt to move the resource group over to the second node, or similarly, do not

shut down the first node while the second is up, before the installation is completed on

the second node.

2. Perform the installation procedure for the second node as described in “Installing the

Interplay Engine on the First Node” on page 84. In contrast to the installation on the first

node, the installer automatically detects all settings previously entered on the first node.

The Attention dialog box opens.

3. Click OK.

4. The same installation dialog boxes will open that you saw before, except for the cluster

related settings that only need to be entered once. Enter the requested information and

allow the installation to proceed.

cMake 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. The installation procedure requires the machine to restart (up to twice). Allow the restart

as requested.

Bringing the Interplay Engine Online

To bring the Interplay Engine online:

1. Click Start and select Programs > Administrative Tools > Cluster Administrator.

2. Click Groups and right-click Avid Workgroup Server and select Bring on line.

All resources are now online.

Installing a Permanent License

During Interplay Engine installation a temporary license for one user is activated

automatically so that you can administer and install the system. There is no time limit for

this license. A permanent license is provided by Avid in the form of a file (*.nxn) on a

CD-ROM.

For more information on managing licenses, see the Avid Interplay Engine and Avid

Interplay Archive Engine Administration Guide.

3 Installing the Interplay Engine for a Failover Cluster

104

To install a permanent license on a clustered system:

1. Start the first node.

2. Insert the Avid Interplay Licenses CD-ROM into a CD drive.

3. Start and log in to the Interplay Administrator.

4. In the Server section of the Interplay Administrator window, click the Licenses icon.

5. Click the Import license button.

6. Browse for the .nxn file on the CD-ROM.

7. Select the file and click Open.

You should see information about the permanent license in the License Types area.

8. Close the Interplay Administrator.

9. Force a failover of the cluster, so that the second node is now active.

10. Repeat steps 3 through 8 on the second node.

Testing the Complete Installation

After you complete all the previously described steps, you are now ready to test the

installation. Make yourself familiar with the Cluster Administrator and review the different

failover-related settings.

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.

Testing the Complete Installation

105

2. Start an Interplay Administrator, install the licenses if needed, create a test database and

add some files to it. If the other node is also running, you are ready to test the failover

functionality.

3. Initiate a failover by moving the resource group; do this through the context menu of the

resource group. Failures can also be simulated, again through the context menu of the

appropriate resource.

nFailures do not necessarily initiate failover.

4. You might also want to experiment by terminating the Interplay Engine manually using

the Windows Task Manager (NxNServer.exe). This is also a good way to get familiar

with the failover settings which can be found in the Properties Panel of the Avid

Workgroup resource, under the Advanced tab.

5. Look at the related settings of the resource group. If you need to change any

configuration files, make sure that the Avid Workgroup Disk resource is online; the

configuration files can be found on the resource drive in the Workgroup_Data folder.

3 Installing the Interplay Engine for a Failover Cluster

106

Updating a Clustered Installation (Rolling

Upgrade)

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.

nFor information about updating specific versions of the Interplay Engine and a cluster, see

the Avid Interplay ReadMe. The ReadMe describes an alternative method of updating a

cluster, in which you lock and deactivate the database before you begin the update.

When updating a clustered installation, the settings that were entered to set up the cluster

resources cannot be changed. Additionally, all other values must be reused, so Avid strongly

recommends choosing the Typical installation mode. Changes to the fundamental attributes

can only be achieved by uninstalling both nodes first and installing again with the new

settings.

Make sure you follow the procedure in this order, otherwise you might end up with a

corrupted installation.

To update a cluster:

1. Determine which node is active.

a. Select Control Panel > Administrative Tools > Cluster Administrator.

b. Open the Groups folder and check the owner column for the Avid Workgroup

Server.

Consider this the first node.

2. Make sure this node is also the owner of the Cluster and the MSDTC groups. If these

groups are not on the active node, right-click each group and select Move Group.

3. Run the Interplay Engine installer to update the installation on the non-active node

(second node). Select Typical mode to reuse values set during the previous installation

on that node. Restart as requested and continue with Part 2 of the installation. The

installer will ask you to restart again after Part 2.

cDo not move the Avid Workgroup Server resource group to the second node yet.

4. Make sure that first node is active. Run the Interplay Engine installer to update the

installation on the first node. Select Typical mode so that all values are reused.

Uninstalling the Interplay Engine on a Clustered System

107

5. During the installation, the installer displays a dialog box that asks you to move the Avid

Workgroup Server group to the second node. Move the group, then click OK in the

installation dialog box to continue. Restart as requested and continue with Part 2 of the

installation. The installer will ask you to restart again after Part 2.

6. You might want to test the final result of the update by moving the server back to the

first node. The Interplay Administrator can be used to display the version of the server.

After completing the above steps, your entire clustered installation is updated to the new

version. Should you encounter any complications or face a specialized situation, contact

Avid Support as instructed in “If You Need Help” on page 10.

Uninstalling the Interplay Engine on a Clustered

System

To uninstall the Avid Interplay Engine, use the Avid Interplay Engine uninstaller, first on the

inactive node, then on the active node.

cThe uninstall mechanism of the cluster resources only functions properly if the names

of the resources or the resource groups are not changed. Never change these names.

To uninstall the Interplay Engine:

1. If you plan to reinstall the Interplay Engine and reuse the existing database, create a

complete backup of the AvidWG database and the _InternalData database in

S:\Workgroup_Databases. For information about creating a backup, see “Creating and

Restoring Database Backups” in the Avid Interplay Engine and Avid Interplay Archive

Engine Administration Guide.

2. (Dual-connected configuration only) Remove the second network address within the

Avid Workgroup Server group.

a. In the Cluster Administrator, right-click Avid Workgroup Server.

b. Right-click Avid Workgroup Address 2 and select Remove.

3. Make sure that both nodes are running before you start the uninstaller.

4. On the inactive node (the node that does not own the Avid Workgroup Server resource

group), start the uninstaller by selecting Programs > Avid > Avid Interplay Engine >

Uninstall Avid Interplay Engine.

5. When you are asked if you want to delete the cluster resources, click No.

3 Installing the Interplay Engine for a Failover Cluster

108

6. When you are asked if you want to restart the system, click Yes.

7. At the end of the uninstallation process, if you are asked to restart the system, click Yes.

8. After the uninstallation on the inactive node is complete, wait until the last restart is

done. Then open the Cluster Administrator on the active node and make sure the

inactive node is shown as online. (The nodes are shown in the lower part of the tree on

the left side of the Cluster Administrator.)

9. Start the uninstallation on the active node (the node that owns the Avid Workgroup

Resource Group).

10. When you are asked if you want to delete the cluster resources, click Yes.

A confirmation dialog box opens.

11. Click Yes.

12. When you are asked if you want to restart the system, click Yes.

13. At the end of the uninstallation process, if you are asked to restart the system, click Yes.

14. After the uninstallation is complete, but before you reinstall the Interplay Engine,

rename the folder S:\Workgroup_Data (for example, S:\Workgroup_Data_Old) so that it

will be preserved during the reinstallation process. In case of a problem with the new

installation, you can check the old configuration information in that folder.

cIf you do not rename the Workgroup_Data, the reinstallation might fail because of old

configuration files within the folder. Make sure to rename the folder before you

reinstall the Interplay Engine.

4Automatic 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 (nodes) directly. Use the virtual network name or IP address that

has been assigned to the Interplay Engine resource group (see “List of IP Addresses and

Network Names” on page 43). Never use the actual physical names or IP addresses of the

machines that are part of the cluster.

Make Sure to Connect to the Interplay Engine Resource Group

The network names and the virtual IP addresses resolve to the physical machine they are

being hosted on. For example, it is possible to mistakenly connect to the Interplay Engine

using the network name or IP address of the cluster group (see “List of IP Addresses and

Network Names” on page 43). The server is found using the alternative address also, but

only while it is online on the same node. Therefore, under no circumstances connect the

clients to a network name other than what was used to set up the Interplay Engine resource

group.

Do Not Rename Resources

Do not rename resources. The resource plugin, the installer, and the uninstaller all depend on

the names of the cluster resources. These are assigned by the installer and even though it is

possible to modify them using the cluster administrator, doing so corrupts the installation

and is most likely to result in the server not functioning properly.

Do Not Install the Interplay Engine 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. This is because local changes are also necessary on both machines. Also,

with independent installations you can later use a rolling upgrade approach, upgrading each

node individually without affecting the operation of the cluster. The Microsoft

documentation is also strongly against installing on shared disks.

4 Automatic Server Failover Tips and Rules

110

Do Not Change the Interplay Engine Server Execution User

The domain account that was entered when setting up the cluster (the Cluster Service

Account —see “Before You Begin the Server Failover Installation” on page 42) also has to

be the Server Execution User of the Interplay Engine. Given that you cannot easily change

the cluster user, the Interplay Engine execution user has to stay fixed as well. For more

information, see “Troubleshooting the Server Execution User Account” in the Avid Interplay

Engine and Avid Interplay Archive Engine Administration Guide.

Do Not Edit the Registry While the Server is Offline

If you edit the registry while the server is offline, you will lose your changes. This is

something that most likely will happen to you since it is very easy to forget the implications

of the registry replication. Remember that the registry is restored by the resource monitor

before the process is put online, thereby wiping out any changes that you made while the

resource (the server) was offline. Only changes that take place while the resource is online

are accepted.

Do Not Remove the Dependencies of the Affiliated Services

The TCP-COM Bridge, the Preview Server, and the Server Browser services must be in the

same resource group and assigned to depend on the server. Removing these dependencies

might speed up some operations but prohibit automatic failure recovery in some scenarios.

Consider Disabling Failover When Experimenting

If you are performing changes that could make the Avid Interplay Engine fail, consider

disabling failover. The default behavior is to restart the server twice (threshold = 3) and then

initiate the failover, with the entire procedure repeating several times before final failure.

This can take quite a while.

111

Changing the CCS

If you specify the wrong Central Configuration Server (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. Make sure to set the CMS to a valid entry while

the Interplay Engine is online, otherwise your changes to the registry won't be effective.

After the registry is updated, stop and restart the server using the Cluster Administrator (in

the Administration Tools folder in Windows).

Specifying an incorrect CCS can prevent login. See “Troubleshooting Login Problems” in

the Avid Interplay Engine and Avid Interplay Archive Engine Administration Guide.

For more information, see “Understanding the Central Configuration Server” in the Avid

Interplay Engine and Avid Interplay Archive Engine Administration Guide.
