Abstract
Technology for minimizing disruptions when host data on a physical volume is encapsulated into a virtualization layer or de-encapsulated is disclosed. Evaluation of a physical volume used as data storage for a virtualization layer before committing to direct access to the physical volume is enabled by preventing direct access before presenting the physical volume directly to the host and by preventing the virtualization layer from moving data on the physical volume while redirecting to the physical volume a first plurality of I/O requests that were directed to the virtualization layer.
