You can migrate two existing Operation Center (OC) or standalone appliances to form a failover pair.

Following are the pre-requisites for migrating existing systems as a failover pair:

  • Two supported NetMRI appliances with licenses installed. You can choose an existing appliance and a second appliance of the same model.

  • The management IP addresses of the two nodes that create the Automatic Failover pair are set to use the same subnet.

To migrate two existing systems to form a failover pair:

Note

In the steps below, the system that is referred to as the second appliance takes the primary role and the system that is referred to as the existing appliance takes the secondary role in the failover pair.

  1. Choose an existing NetMRI system and configure a second NetMRI system of the same model NetMRI version.

  2. If you are using scan ports, connect the scan ports of all systems to the same network. For information, see the Failover and Scan Interfaces topic in the NetMRI online Help.

  3. Run the Setup Wizard on the second system and set the admin password and install the license. The admin password and time settings must be the same on both systems. For information about the Setup Wizard, see the Running the Setup Wizard topic and its subsections in the NetMRI online Help.

  4. Exit the Setup Wizard after setting the password and installing the license on the second system.

  5. If you want to use the management IP address of your existing system as the VIP of the failover pair, then you must change the management IP address of the existing system.

  6. To configure the second system to take the role of the primary system, do the following:

    1. Log into the second system.

    2. Go to Settings > Setup > Failover Configuration.

    3. On the Failover Configuration page, configure the settings. For more information, see the Specifying Automatic Failover Settings topic in the NetMRI online Help.
      Note that after specifying the failover configuration settings and completing the enable operation, the systems start synchronizing data. This process might take up to one hour, depending on network and storage speeds. For details about how to configure these settings, refer to the Infoblox NetMRI Administrator Guide.

  7. For an Operation Center, complete the following:

    1. Log in to the administrative shell on the Operation Center and run the reset tunserver and configure tunserver commands. Enter the VIP address of the Operation Center when prompted for the IP address of the Operation Center server.

    2. Log in to the administrative shell on each Collector and run the reset tunclient and register tunclient commands. Enter the VIP address of the Operation Center when prompted for the IP address of the Operation Center.
