Abstract
A method is used in managing ownership of logical volumes. A path to a logical volume is determined, where upper-layer software selects the path to the logical volume. Based on the selection of the path, ownership of the logical volume is assigned. Lower-layer software assigns ownership of the logical volume based on information received from the upper-layer software.
