Check if the Master Data store is up. If yes, try to activate at least 1 host.
Once a host is up, the Datacenter will go up and everything should get better.

Hi Team

due to some reasons one of our  slef hosted engine went down, hence we provisioned new centos vm and restored the hosted engine backup file. After restoring we could see all the Datacenter, cluster, storage, hosts and vm entities in restored ovirt engine but they all are offline.

please help us how to we connect all the running hosts and storage domain, vms back to restored hosted engine.  do we need to get a down time for all the vms to restore the hosts? how do I activate all the existing storage domains as is.
