Let's summarize : one ESXi machine in our 3 nodes cluster has broken down. We want to replace it with another HP server with same IP address, admin account etc ... Things are going well in adding this new node until we stay plugged in the following intermediate state where every VSA looks like disconnected. Just above the three lines concerning the VSA, we notice a fourth line called host-103 with the same IP address than the ESX we try to add (125.0.12.3). It looks like VSA Manager has lost all its connections with the cluster. Any idea to make the process go further on ?
