Abstract
A method to import a logical volume and first storage attributes assigned to that logical volume into a second virtual tape system from a first virtual tape system. The method assigns one or more first storage attributes to that logical volume, assigns an identifier, and writes an export physical volume comprising the logical volume, the first storage attributes, and the identifier. The method then imports the logical volume, the logical volume identifier, and the first storage attributes, into the second virtual tape system, and associates one or more construct overridden flags with the logical volume if the second virtual tape system specifies use of one or more of second storage attributes.
