When I first installed my 3.6 oVirt cluster, there was a bug where the 
storage domain didn't show up after first deploy. I have since upgraded 
the cluster to the latest oVirt 3.6, and the sotrage domain appeared, 
however I never tried to import it until now.

Thanks. My reason for looking into this is I need to reboot my prod SAN 
switch. I have the ports split between my two SAN switches, however only 
hostedengine is not multi-path, so during a reboot I will loose access 
to the LUN.

Any solutions to the problem with oVirt? Shutting down the cluster is 
not an option.
