       • Enable GUI Redirect from Member: Select this checkbox to allow the appliance to redirect the Infoblox GUI from a Grid member to the Grid Master.

         Note that if read-only API access is enabled for a Grid Master Candidate, then selecting the Enable GUI Redirect from Member checkbox for the Grid Master Candidate does not redirect the Infoblox GUI from the Grid Master Candidate to the Grid Master. For more information about enabling read-only API access on a Grid Master Candidate, see Enabling Read-only API Access on the Grid Master Candidate below.

       • Enable GUI/API Access via both MGMT and LAN1/VIP: Select this checkbox to allow access to the Infoblox GUI and API using both the MGMT and LAN1 ports for standalone appliances and MGMT and VIP ports for an HA pair. This feature is valid only if you have enabled the MGMT port. For information about enabling the MGMT port, see Appliance ManagementUsing the Using the MGMT Port.

         Note that the appliance uses the MGMT port only to redirect the Infoblox GUI from a Grid member to the Grid Master even after you enable the Enable GUI/API Access via both MGMT and LAN1/VIP feature.

   • Show Restart Banner: Select this checkbox to enable the appliance to display the Restart Banner at the top of Grid Manager whenever the appliance notifies you that a service restart is required.

   • Require Name: Select this checkbox to prompt the administrator to input the username before performing the service restart. When you select this checkbox, the appliance displays the Confirm Restart Services dialog box. Enter the username in the Name field and click Restart Services. For information about restarting service, see Restarting Services.

4. Save the configuration.

If you changed the VPN port number, time zone, date or time, Grid Manager displays a warning indicating that a product restart is required. Click Yes to continue, and then log back in to Grid Manager after the application restarts.

Use Grid Manager, to configure a group of users that are allowed to delete or schedule the deletion of a network container, its child objects, a zone and the zone’s child objects. For instructions on deleting a network container or a zone, see Deleting Network Containers and Removing Zones.
When you select All Users or Superusers, these users can choose to delete a parent object and reparent its child objects, or they can choose to delete a parent object and all its child objects. These options appear only if a network container or a zone has child objects. For instructions on scheduling recursive deletion of network containers and zones, see Scheduling Recursive Deletions of Network Containers and Zones.
When you select Nobody, all the users can delete the parent object only. All the child objects, if any, are re-parented. For more information about scheduling deletions, see as described in Scheduling Deletions .Note that you can restrict specific users to perform recursive deletions of network containers and zones only through Grid Manager. These settings do not prevent other users from performing recursive deletions through the API.

...

The appliance puts all deleted objects in the Recycle Bin, if enabled. You can restore the objects if necessary. When you restore a parent object from the Recycle Bin, all its contents, if any, are re-parented to the restored parent object. For information about Recycle Bin, see Finding and Restoring Data.
To configure the group of users to perform recursive deletions:

To promote a Grid Master candidate to a Grid Master, you must have already designated a member as a Grid Master Candidate, by selecting the Master Candidate option in the General tab of the Grid Member Properties editor. You can designate any member as a Grid Master Candidate. The Grid Master Candidate gets a complete copy of the Grid database. Therefore, Infoblox recommends that you configure the same appliance models for the Grid Master and Grid Master Candidates. By default, the Grid Master promotion uses UDP port 1194. Make sure that the UDP 2114 and UDP 1194 ports are open between the Grid members and a newly designated Grid Master. During a Grid Master promotion, the newly promoted Grid Master continuously contacts all Grid members, including the original Grid Master on the UDP port 2114, until it reaches them. Upon reaching them, the newly promoted Grid Master notifies all Grid members that it is the new Grid Master. Next, the Grid Members restart and attempt to establish normal Grid communications (via BloxSync) with the newly promoted Grid Master. Before promoting a Grid Master Candidate, check your firewall rules to ensure that the Master Candidate can communicate with all the Grid members. For information about grid communications, see About Grids.

Testing the Connection of the Master Candidate with the Grid Members

Before promoting a Grid Master Candidate, check whether the Grid Master Candidate is connected to the rest of the Grid members, by scheduling a test promotion. You can do this either by using Grid Manager or by using the NIOS CLI. For information about scheduling a test promotion by using the NIOS CLI, see show test_promote_master and set test_promote_master.

The connection of the Grid Master Candidate to the rest of the Grid members is checked by sending specifically crafted test packets from the Grid Master Candidate and checking whether the Grid members are able to receive these packets.

...

1. Establish a serial connection (through a serial console or remote access using SSH) to the Master Candidate. For information about making a serial connection, as described in Method 2-Using the CLI, see Deploying a Single Independent Appliance.

2. At the CLI prompt, use the command set promote_master to promote the Master Candidate and send notifications to all Grid members immediately, or promote the Master Candidate to the Grid Master immediately and specify the delay time for the Grid members to join the new Grid Master. For more information about the command, refer to the Infoblox CLI Guide.

3. To verify the new master is operating properly, log in to the Infoblox Grid Manager on the new master using the VIP address for an HA master or the IP address of the LAN1 port for a single master.

4. Check the icons in the Status column. Also, select the master, and then click the Detailed Status icon in the table toolbar. You can also check the status icons of the Grid members to verify that all Grid members have connected to the new master. If you have configured delay time for Grid member notification, it will take some time for some members to connect to the new master. You can also check your firewall rules and log in to the CLI to investigate those members.

Reconnecting Groups After Grid Master Candidate Promotion

...

After enabling the Grid Master Candidate group promotion, use the set promote_master CLI command to start the Grid Master Candidate promotion.
Use the set gmc_promotion disable CLI command to disable the Activate GMC Group Promotion Schedule option. Note that, this command can be executed on Grid Master and Grid Master Candidate. For more information see, set gmc_promotion.
