If your Cryptographic Security Platform comprises more than one node, you need to join them on a cluster. 

To join Cryptographic Security Platform nodes

1. In all the nodes:
   1. Make sure the node meets the Requirements. 
   2. If not yet installed, install the Cryptographic Security Platform image as explained in Installing the image.
2. In one of the nodes:
   1. Install Cryptographic Security Platform as explained in Installing CSP.
   2. Run clusterctl node info and copy the node IP address.
   3. Run clusterctl node join-token and copy the node joining token.
3. In the rest of the nodes, perform the following steps sequentially.
   1. Run the clusterctl node add command with the IP address and joining token previously obtained.
   2. Wait for the command to complete before proceeding to join another node.

      Do not perform any operations on the cluster nodes until this operation completes.

4. Redeploy each deployed Entrust solution (if any) using either the clusterctl solution deploy command or the Management Console.
