For example. Let us take host1, host2, host3 form the cluster POD. Now admin prefers to expand this cluster, with 3 more nodes host4, host5, host6. In this case, admin need to SSH public key authentication from host4 -> host4, host4 -> host5, host4-> host6 Version-Release number of selected component (if applicable): -------------------------------------------------------------- RHHI 2.0 Day2 doc Expected results: ---------------- Add documentation that there should be a SSH public key authentication from the following hosts: 1. First host in the cluster to all the hosts ( including the same host, and nodes to be expanded ) 2. First host in the newly added set of 3 nodes to all the newly added nodes( including the self )
