[ovirt-users] Data(Master)

Hi users, I'm using oVirt 3.4 on rhel 6.5 and it's working perfectly, but when i'm setting up another Hypervisor and ovirt-engine I accidentally attach my working storage "Data(Master)" to my 2nd one, and my problem is i'm unable to re-attach it to my first one, is it possible to re-attach it without loosing my vm guest disk images? And when I accidentally attach it to my 2nd one, It prompt me that "This operation might be unrecoverable and distructive" is there a change that my 25 vm guest disk images will be erased? God Bless. TIA Sandvik
