Methods, systems, and computer program products for postponing bitmap transfers and eliminating configuration information transfers during trespass operations in a disk array environment
Methods, systems, and computer program products for postponing bitmap transfers and eliminating configuration information transfers during trespass operations in a disk array environment are disclosed. According to one method, a clone group is stored on a disk array, the clone group including a logical unit (LUN) representing a storage partition on the disk array and a clone of the LUN, the clone being a copy of the data referenced by the LUN. The clone group is associated with a first storage processor (SP) for writing data to the disk array. Changes between the LUN and the clone are tracked by maintaining a data structure indicative of the changes in a memory associated with the first SP. The association of the clone group is changed to a second SP for writing data to the disk array without transferring the data structure to memory associated with the second SP.
