ABSTRACT:
Provided are a method, system, and article of manufacture for relocating a logical volume from a first storage location to a second storage location using a copy relationship. An operation is initiated to move a logical volume from a first storage location to a second storage location. A relationship is established between the first and second storage locations to copy data in the logical volume from the first storage location to the second storage location. A read request is received to data in the logical volume while copying the data in the logical volume from the first storage location to the second storage location. A determination is made, in response to the read request, whether the requested data is at a first copy of the logical volume in the first storage location or a second copy of the logical volume at the second storage location. The requested data is returned from the determined first or second copy of the logical volume while the logical volume is being copied from the first storage location to the second storage location.
