Bug Description

The connect_volume and disconnect_volume code in brick assumes that the targets for different portals are the same for the same multipath device. This is true for some arrays but not for others. When there are different targets associated with different portals for the same multipath device, multipath doesn't work properly during copy image to volume and copy volume to image operations.
