You may provision a Port Reservation for the new Grid Member. When doing so, you select the device to which you expect the new Grid Member to connect; In the context of a Grid member, this device type is usually an Ethernet Switch or Switch-Router. The Add Grid Member Wizard provides a step in which you define the port reservation settings, as described in the following section Adding a Single Member. The process also can be applied when defining an HA pair, as described in the sections Creating an HA Grid Master and Adding an HA Member. |
You can add single appliances and HA pairs to a Grid, forming single members and HA members respectively. A single Grid member can be either an Infoblox appliance or a vNIOS appliance. You can configure Grid members in either IPv4, IPv6, or dual mode (IPv4 and IPv6). For information about which vNIOS appliance supports configuration as an HA Grid member, see vNIOS Appliances.
You can also define an HA member on the Grid Master and then add two individual NIOS appliances to the Grid as Node 1 and Node 2 to complete the HA member you defined on the master.
New members inherit all settings that you create at the Grid level unless you override them at the member level. You can also define port reservations for the network infrastructure devices to which the Grid members will connect.
The process for adding either a single appliance or HA pair to a Grid involves the following steps:
...
The communication protocol for all the services in a dual mode (IPv4 and IPv6) Grid member is set to IPv4, by default. You can change the default communication protocol for all the services. For information, see Changing the bookmark636 Communication Protocol for a Dual Mode Appliance.
...
- Define the network settings of the HA pair on the Grid Master.
- Initiate the join Grid operation, during which you specify the VIP or IP address of the Grid Master, the Grid name, and the shared secret on the HA pair. For information, see Joining Appliances to the Grid.bookmark638
In addition, on the Grid Master you can configure the service settings such as DNS zones and records, DHCP networks and address ranges, and so on for a member before or after you join the HA pair to the Grid. The basic steps for adding an HA member are presented below.
...
The communication protocol for all the services in a dual mode (IPv4 and IPv6) HA member is the same protocol as the one that is used for VRRP advertisements. For example, if you select IPv4 in the Send HA and Grid Communication over field in step 2 of the Add Grid Member wizard, then IPv4 is set as the communication protocol for all the services. However, you can override the communication protocol for all the services in a dual mode HA member. For information, see Changing the bookmark636 Communication Protocol for a Dual Mode Appliance.

- From the Grid tab, select the Grid Manager tab -> Members tab -> member checkbox -> Edit icon.
- In the Grid Member Properties editor, select the Network tab -> Basic tab, and then complete the following:
- Communication Protocol Settings and Preferences: This setting is not applicable for an HA pair. Select either IPv4 or IPv6 from the drop-down list. This setting will force the appliance to use the specified protocol for Grid and reporting services and this is the preferred protocol for services with two types of resolution (A and AAAA records).
- Customized Settings: Select this and do the following:
- Always use this Communications Protocol for: For a Grid Master, you can select either IPv4 or IPv6 from the Reporting drop-down list. This setting will force the Grid Master to use the specified communication protocol for reporting service. For a Grid member, you can select either IPv4 or IPv6 from the Grid and Reporting drop-down list. This setting will force the Grid member to use the specified communication protocol for Grid and reporting service.
- Always Prefer this Communications Protocol for: This field lists the services which has two types of resolution (A and AAAA records). Select either IPv4 or IPv6 from the drop-down list for the service which you want the appliance to use this as the preferred communication protocol. The appliance uses the preferred protocol first for the service.

Grid members can join the Grid using IPv4 protocol in an IPv4-only Grid and using IPv6 protocol in an IPv6-only Grid. In a dual mode Grid, the Grid members may join the Grid using IPv4 or IPv6. Similarly, a Grid Master candidate can join the Grid using IPv4 in an IPv4-only Grid and using IPv6 in an IPv6-only Grid. But for a Grid Master candidate to join a dual mode Grid, it should be configured in dual mode. If you have configured the MGMT port for the Grid member, then the Grid member can join the Grid using the MGMT port. You can use the Grid Setup Wizard or access the Join Grid dialog box to join appliances to a Grid. The Grid Setup Wizard launches when you first log in to an appliance. You can also launch it from the Toolbar as described in Grid Setup Wizard.
To join a single appliance and HA pair to a Grid using the Grid Manager GUI:
