[ovirt-users] oVirt disk disappeared after importing iSCSI domain

Hi all oVirt experts. So, I managed to f.. up a VM today. I had one VM running on a oVirt 4.3 cluster, where the disk was located on an iSCSI data domain. I stopped the VM, put the storage domain in maintenance mode, detached adn removed the storage domain from the ovirt 4.3 cluster. Then I imported the storage domain to our new oVirt 4.4.1 cluster, let the process convert it from V4 to V5 format and activated the storage domain in the new cluster. Entering the information page for the imported storage domain, I expected to see "Import VM" and "Import Disk" menus, but these menues did not appear as they did for other storage domains that I successfully had moved from old to new cluster. Clicking "Scan Disks" did not help either. So, now I am stuck with a storage domain where the VM's disk is located, but oVirt is not able to see the disk. What can I do to recover the lost disk from the storage domain? Any CLI commands available in ovirt 4.4.1 would be nice. Thanks in advance for your quick and good help.
