    Hi Idan,<br>
    <br>
    Thanks a lot for your answer, that's clear now.<br>
    I will change my setup and use 2 cluster in the same DC instead.<br>
    In the case using 2 cluster in the same DC I've noticed that all
    Storage domain have to be available for all clusters, in my case I
    use SAN Storage. Is this by design or is there a way to have some
    Storage Domain only available on one cluster but not on the others?<br>
    <br>
    Regards,<br>
    Arsène<br>

          <div>Hi Arsène,<br>
            <br>
          </div>
          The only storage domain that can be shared between datacenters
          is the iso domain<br>
          But that's not what you're looking for. You can't share a data
          domain between two datacenters.<br>
          <br>
        </div>
        <div>As for importing a storage domain which is active on one
          datacenter to another datacenter, there are two cases:<br>
        </div>
        <div>- If the datacenters are in the same oVirt setup, that
          won't be possible, and the operation will not be performed.<br>
        </div>
        <div>- If the datacenters are in two different oVirt setups, the
          import to the second datacenter will succeed, but you will
          experience issues in the first datacenter.<br>
        </div>
        <div>The reason for that is that the host in the second
          datacenter overrides the storage domain metadata when
          importing it.<br>
          <br>
        </div>
        <div>Therefore, you cannot import a storage domain to a second
          datacenter while it is active on the first one, anyway.<br>

              Thanks for your information but....<br>
              When I'm writing about DC I mean defined DC in oVirt and
              so far I could see that when you define a storage domain
              in one oVirt DC it will not be available in another DC and
              I don't know what would happen if I would import it on the
              second DC.<br>
              In your setup, did you just define 1 DC and multiple
              clusters?<br>
              <br>
