Changing a KeyControl Mapping

1. Log into the KeyControl webGUI using an account with Cloud Admin privileges.
2. In the top menu bar, click Cloud.
3. Click the Mappings tab.
4. Select the Mapping you want to change in the list, then select Actions > Edit Mapping.

5. If you want to add a new IP address, click the + (Plus sign) on the right-hand side of the dialog box to add a new row, then enter the following information:

   Field Descriptions

   Field	Description
   Description	Enter a description for this node that lets you distinguish it from other nodes in the KeyControl Mapping.
   Hostname or IP	The hostname or IP address to which this node should be mapped. This name or address should be accessible to the VMs that will be connected to KeyControl using this KeyControl Mapping.
   Port	The port number for the specified Hostname or IP address. The default is 443.
   Node drop-down	Select the appropriate node in the drop-down list. You can only have one entry for each node.
   Enabled/Disabled	Select Enabled if the node is available to the VMs associated with this Mapping. If you want to use this a placeholder until you bring the node online, select Disabled. The default is Enabled.

6. If you want to delete an existing entry, click the – (Minus sign) at the end of the row you want to delete.

7. When you are done changing the list of nodes, make sure that the order is correct because the order of the IP addresses in the list determines the order of precedence. The first node in a KeyControl Mapping is considered the preferred node, and all VMs will use that node as long as it is available. If the preferred node is offline when a VM heartbeats, the VM will try the other IP addresses in the Mapping, starting with the second IP address in the list and working downwards. Once the VM finds an available KeyControl node, it will use that node to complete the current heartbeat, and it will continue to use that node until the cluster returns to a healthy state. After the cluster becomes healthy, the VM will resume using the preferred node at its next heartbeat.

   If you need to change the order, click and hold on the arrow icon at the beginning of the line to drag the entry to the proper position. Release the mouse to drop the entry in the new location.

8. When you are done, click Update. KeyControl communicates the changes to the associated VMs on their next heartbeat.
