[ovirt-users] Data Center, Cluster and Storage Domains show as "Down" after backup and restore

Hi Everybody, So I did a full backup of our HE, redeployed and restored. After the restore, I ran engine-setup on the newly deployed HE. I can access the the environment as per normal, the only issue is that everything still shows as "down", this includes hosts and VMs? Is there something I need to do in order to get everything to display as "Up" again? Thanks
