[ovirt-users] FCP storage domain wiped, recovery process

I’ve got an environment with: 13 servers in the oVirt default cluster Hosted Engine 4.1.3.5-1.el7.centos Storage provided by FC san One of the FC LUNs, being used as a Data Domain, was wiped/reformatted through a confluence of events. How can I clean this up and re-add this LUN back? I can’t Detach it, as there are VMs/Templates attached to it. When I try to remove the Templates, it tells me it can’t since the storage domain is inactive. What’s the best way to clean up from this? Thanks
