Installing TrueSight Network Automation on a Windows HA cluster

To install TrueSight Network Automation on a cluster for high availability (HA), you must install the product separately on each node in the Windows cluster. This topic includes the following sections:

• Before you begin installing the primary TrueSight Network Automation server
• To install the primary Network Automation server
• Before you begin installing the secondary TrueSight Network Automation server
• To install the secondary Network Automation server
• Installing Network Automation remote device agents in a cluster
• Configuring Network Automation for HA

Before you begin installing the primary TrueSight Network Automation server

• Ensure that the cluster setup is ready with the shared disk.
• Ensure that Microsoft Windows .Net framework is installed on both the computers.
• Ensure that the cluster is active on the primary node.

To install the primary Network Automation server

1. Install the primary Network Automation server. For instructions, see Installing-the-application-server-on-Windows. 
   
   

   Warning

   Note

   With the exception of the following steps, which differ, the installation sequence in an HA cluster is the same as that for a standalone application server.

2. Data Directory Information panel: Specify the cluster shared disk, for example, T:\BCA-Networks-Data in the Data Directory field, and click Next.
3. Certificate Information panel: Enter the host name of the cluster for the HTTPS certificate, and click Next.

Configuring Network Automation for HA

The following sections provide instructions for configuring Network Automation for high availability (HA).

Before you begin

To configure Network Automation for HA, you can use any clustering technology and you can configure it accordingly with the help of your cluster administrator.

To configure the TrueSight Network Automation service as a generic service on a Windows cluster

To support Network Automation installation in an HA environment, you must add the Network Automation web service to the clustered application generic services.

1. In the Microsoft Failover Cluster Manager, right-click Services and applications, and then click Configure a Service or Application from the left navigation pane.                                    
2. In the High Availability Wizard: Before you Begin panel, click Next.
3. In the Select Service or Application panel, select Generic Service, and click Next.
4. In the Select Service panel, select the BCA-Networks Web Server web service, and click Next.
5. In the Client Access Point panel, perform the following substeps, and click Next. 
   
   1. Specify a name for the web service that clients will use when accessing the service, for example TSNA.
   2. Select a network, and then add a new virtual IP address to which the service would be assigned and running on the cluster.
6. In the Select Storage panel, do not select a shared volume, and click Next.
7. Click Next until the Configure High Availability panel appears appears.
8. Click Finish to complete the configuration.
9. After the service is created, add the shared disk to the created generic service.
