Adding the Second Node for HA:
Before you install Unified CCX 8.5(1) on the second node, you must add the server details of second node on the first node using the Cisco Unified CCX Administration Web interface.
To configure a new server that needs to be added to form a Unified CCX cluster for an HA setup, complete the following steps:
Step 1 On the Cisco Unified CCX Administration Web interface of the first node, choose System > License Information > Add License(s).
Step 2 Browse to select an HA premium or enhanced license and click Upload.
Step 3 Once the HA license is successfully uploaded and validated, choose System > Server. The List Servers window displays.
You can use the List Servers window to view, add, and remove servers in the cluster.
Step 4 Click Add New. The Server Configuration window displays.
Note: If you have not uploaded an HA license yet, you will be prompted with a warning message to upload one. Click OK to go to the License Information window and upload.
Step 5 In the Server Configuration window, enter the values for the following fields:
Note: You can add only one additional node. If you have already installed two nodes in the cluster or if you have a Unified CME deployment, the server details of only one node is displayed in this window and the Add New button is disabled.
Step 6 Click Add to add details of the new server.
Step 7 You can now start installing the second node for HA.
Hope it helps.
