I need to move a direct LUN from ISCSI storage to FC storage.

I have one ISCSI SAN and one FC SAN connected to my ovirt environment.

I need to migrate all my data from the ISCSI SAN to the FC SAN.

It is no problem to move the images from ISCSI to FC however i also have direct LUN:s attached from the ISCSI SAN that i need to move to FC however when i mark the direct LUN the "move" button is greyed out? How do i move the direct LUN?

Regards

Christian
