After you deploy a vNIOS appliance for KVM, you can configure it as a single or an HA Grid Master. To configure a vNIOS HA Grid Master, deploy two vNIOS appliances and define the network settings for each node. The procedure is the same as joining two physical appliances as an HA pair. You must configure a Grid Master and set up the Grid before you join Grid members.
You configure the vNIOS appliance as a Grid Master using the Infoblox Grid Manager. If you are configuring a vNIOS HA Grid Master, complete the configuration for node 1 as described below. To configure node 2, see Configuring Node 2 for HA Grid Master.
To configure the single Grid Master or node 1 of the HA Grid Master:

  1. On your management system, open a new browser window, and then connect to https://ip_addr, where ip_addr is the address of the single appliance or LAN1 port on node 1.
  2. Log in to the Infoblox Grid Manager using the default user name admin and password infoblox.
  3. Review the End-User License Agreement and click I Accept.
  4. In the Grid Setup wizard, select Configure a Grid Master and click Next.
  5. Complete the following to specify the Grid properties, and then click Next:
    • Grid Name: Enter a text string, such as DaveyJones, that the Grid Master and appliances joining the Grid use to authenticate each other when establishing a VPN tunnel between them. The default Grid name is Infoblox. Note that the VPN MTU (maximum transmission unit) size for any virtual appliance using OpenStack must be 1500 bytes to avoid any inconsistencies in the instance. For more information about MTU, see Setting the MTU for VPN Tunnels.
    • Shared Secret: Enter a text string, such as L0ck37, that the Grid Master and appliances joining the Grid use as a shared secret to authenticate each other when establishing a VPN tunnel between them. The default shared secret is test.
    • Show Password: Select this to display the password. Clear the checkbox to conceal the password.
    • Host name: Enter a valid domain name for the appliance. You can use the name that you entered for the vNIOS appliance when you deployed it.
    • Is the Grid Master an HA pair?: Select No for the single Grid Master. Select Yes for an HA pair.
  1. Complete the following to configure the network settings, and then click Next:
    • HostName: Enter a valid domain name for the appliance.
    • IP Address: Displays the IP address of the LAN port.
    • Subnet Mask: Displays the subnet mask of the LAN port.
    • Gateway: Displays the IP address of the gateway of the subnet on which the LAN port is set.
    • Port Settings: The default is Automatic. You cannot change port settings for vNIOS appliances.
  2. For an HA pair, complete the following to specify the network properties and click Next:
    • VirtualRouterID: Enter the VRID (virtual router ID). This must be a unique VRID number—from 1 to 255—for this subnet.
    • RequiredPortsandAddresses: Enter information about the following virtual interfaces: VIP, Node 1 HA and LAN ports, Node 2 HA and LAN ports. The VIP address and the IP addresses for all the ports must be in the same subnet. Enter the IP address of the gateway for the subnet on which the interfaces are set. This is the same for all interfaces. All fields are required. Note that you cannot change the port settings.
  3. Optionally, enter a new password and click Next. The password must be a single hexadecimal string (no spaces) that is at least four characters long.
  4. Select the time zone of the Grid Master and indicate whether the Grid Master synchronizes its time with an NTP (Network Time Protocol) server, and then click Next.
    • If you choose to enable NTP, click the Add icon and enter the IP address of an NTP server. You can enter IP addresses for multiple NTP servers.
    • If you choose to disable NTP, set the date and time for the appliance.
  5. The last screen displays the settings you specified in the previous panels of the wizard. Verify that the information is correct and click Finish. The application restarts after you click Finish.

    Note: The GridSetup wizard provides options such as not changing the default password and manually entering the time and date. However, changing the password and using an NTP server improve security and accuracy (respectively), and so these choices are presented here.
    Record and retain this information in a safe place. If you forget the shared secret, you need to contact Infoblox Technical Support for help. When you add an appliance to the Grid, you must configure it with the same Grid name, shared secret, and VPN port number that you configure on the Grid Master.

Configuring Node 2 for HA Grid Master

For an HA pair, complete the following to configure node 2:

  1. On your management system, open a new browser window, and connect to https://ip_addr, where ip_addr is the address of the LAN1 port on node 2.
  2. Log in the Infoblox Grid Manager using the default user name and password admin and infoblox.
  3. Review the End-User License Agreement and click I Accept.
  4. In the Grid Setup wizard, select Join Existing Grid and click Next.
  5. Complete the following to specify the Grid properties and click Next.
    • Grid Name: Enter the Grid name you entered for node 1.
    • Grid Master's IP Address: Enter the VIP you entered for node 1.
    • Shared Secret: Enter a the shared secret you entered for node 1.
  6. Verify the IP address settings of the member and click Next.
  7. The last screen displays the settings you specified in the previous panels of the wizard. Verify that the information is correct and click Finish.

The setup of the HA Grid Master is complete. If the two nodes cannot join (it should not take more than a few seconds), check the IP addresses of Node 1 LAN and Node 1 HA (the Grid Master) and for Node 2 LAN and Node 2 HA (the node attempting to join the Grid Master to form the HA Pair). Ensure that the network IP address of node 2 is set to the same value as Node 2 LAN on the Grid Master.
As a method of verifying successful communication, open the console window for node 2. You should see a pair of messages as follows:

Contacting the Grid Master at 10.36.0.200....
Synchronizing database with the Grid Master....

For more information about HA pair configurations, refer to the Infoblox NIOS Documentation.
