You can create a NetMRI failover pair using two NetMRI appliances, in which one acts as the primary appliance and the other as the secondary appliance. A failover pair provides a backup or redundant operational mode between the primary and secondary appliances so you can greatly reduce service downtime when one of them is out of service. You can configure two Operation Center (OC) appliances, collector appliances, or standalone appliances to form a failover pair.

...

1. Set up and configure two new NetMRI appliances as separate systems. Ensure that the appliances are running NetMRI 7.1.1 or later. For collector failover configuration, make sure that the appliances are running NetMRI 7.1.2 or later.
2. Connect both the systems using one of the following methods:
   • Direct replication: Connect the systems directly through their HA ports.
   • Network replication: Connect the HA port of both systems to a network using an Ethernet cable.
     Infoblox recommends that you connect the systems using the direct replication method.

...

1. Run the Setup Wizard on both appliances, set the admin password, and then install the license. The admin password must be the same on both systems. For more information, see Running the Setup Wizard.
   At this point of time, it is not necessary to complete the entire configuration wizard on both systems. You can complete the configuration only on the primary system.

...

1. Configure the failover settings on the Operation Center and collectors, as described in Specifying Automatic Failover Settings.
   
   

   Note
   title Note
   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 the appliance model.

...

1. 
   

2. For an Operation Center and collector failover, complete the following:

1. • Log in to the Admin Shell on the Operation Center and run the configure tunserver command. Enter the VIP address of the Operation Center when prompted for the IP address of the Operation Center server.
   • To register collector on the Operation Center set up, log in to the Admin Shell on each Collector and run the register tunclient command. Enter the VIP address of the Operation Center when prompted for the IP address of the Operation Center.

...

To specify automatic failover configuration settings:

1. Go to the Settings ->  > Setup ->  > Failover Configuration tab.
   The Failover Configuration page appears, listing all device interfaces that are used by the system.
2. In the Failover Configuration page, complete the following:
   
   • • Virtual IP address: Enter the VIP address.
     • Connection Mode: Select the connection mode from the drop-down list. You can select Direct if the systems are connected directly through the HA port, or select Network if the HA port of both the systems are connected to a network. Infoblox recommends that you use the Direct connection mode.
     • Virtual Hostname: Enter the hostname for the system.
     • Port: Enter the TCP port for replication traffic, if you are using Network connection mode. You must enter a port number great than 1024.

   In the Replication Nodes section, enter the following for both Primary and Secondary.

   1. • Role: Displays the role of the appliance, either PRIMARY or SECONDARY.
      • Management IP: Enter the management IP address of the system.
      • Hostname: Enter the hostname of the system.
      • Replication IP: Enter the IP address used for replication traffic, if you are using Network connection mode.
      • Subnet: Enter the subnet mask of the replication IP, if you are using Network connection mode. Note that the subnet mask must be the same for both primary and secondary appliances.

...

1. Click Update to update the settings and replicate data on both the primary and secondary appliances.

...

1. Click Enable to start connecting the systems.
   The secondary system synchronizes data with the primary system. This process might take about one hour, depending on the appliance model.

Migrating Existing Systems as Failover Pairs

...

To migrate existing systems to form a failover pair, perform the steps described in the following sections:

• Preparing Secondary Appliances (Old Partition Scheme)
• Preparing the Existing Operation Center Node (Old Partition Scheme)
• Preparing the Existing Collectors Nodes (Old Partition Scheme)
• Configuring a Failover Pair
• Reconfiguring the Operation Center HA Pair
• Reconfiguring the Collector HA Pair

Note
title Note
For the new partition scheme, configure three nodes—one with an OC license and two others with Stand Alone licenses—with the same version and licenses, and reset the admin password in the GUI to match the other system. Then proceed with the last three steps from the list above.

Preparing Secondary Appliances (Old Partition Scheme)

To prepare a secondary (B) device, complete the following:

1. Install NetMRI with the same version as on node A. If you are using a device that you used earlier, update it to the node A version.
2. If the device was already used, run the reset command on node B.
3. Run the repartition command on node B.

4. Run the config server command on node B. 

   Note
   title Note
   The management port should be in the same network, time zone, etc. as in node A. If you are using scan ports, connect the scan ports of the second node to the network in the same way as in the existing device. For more information, see Failover and Scan Interfaces.

   
   

5. Install the license on node B. The license must have the same type, device limit, and expiration date as node A.

   Note
   title Note
   In the case of an Operation Center, run config server again after the license installation without modifying any parameters.

   
   

6. Reset the admin password in the GUI to match the other system or make UI setup through the Setup Wizard.

...

1. Log in to the Operation Center UI as admin.
2. Go to Settings -> Setup ->  > Setup > Failover Configuration. Here you can see the HA status of your devices scheme (OC and 2 collectors).
3. Choose OC ->  > Edit and configure the Operation Center HA pair. Wait until it is finished and the status is OK.
4. Choose the first collector - > Edit and configure the first collector HA pair. Wait until it is finished and the status is OK.
5. Choose the second collector - > Edit and configure the second collector HA pair. Wait until it is finished and the status is OK.

...

Note
title Note
If devices were discovered from both collectors, e.g. when a device has a few interfaces, these devices are displayed in grey without a sim link to the device viewer on the collector which did not discover first. After the system is migrated, the following issue is observed for one of the collectors (second): In Network Explorer ->  > Discovery, the devices listed on the left from the initial collection and discovered by both collectors cannot be discovered or deleted using the Discover Now or Delete button. However, you can discover them from Settings ->  > Discovery Settings - >  > Seed Routers/CIDR.
