Issue/Introduction
This article provides recovery steps for a scenario where 2 of the 3 NSX nodes are lost or are no longer functional.
A 3 node NSX-T cluster will continue to be fully functional if 1 node is lost however when 2 nodes are lost, the cluster will no longer be operational as the majority has been lost.
With only 1 node remaining, it is no longer possible to login to the UI.

Environment
VMware NSX-T Data Center
VMware NSX-T Data Center 2.x

Resolution
The official and supported procedure to recover the NSX node cluster is to deploy a new appliance, restore from backup and then add two additional nodes.
In the event that a restore from backup is not possible, there is a possibility GSS may be able to recover the cluster from the remaining working node. If required, please open a Support Request with GSS to investigate that option further.
