Abstract

Methods and systems are disclosed that enable data migration from a source logical volume to a target logical volume in signal communication with the source logical volume with minimal disruption to the accessibility of that data. The coherency of data on the source logical volume and the target logical volume is confirmed. A first pseudoname is unmapped from a source logical volume identifier, and a second pseudoname is unmapped from a target logical volume identifier. A logical volume identifier includes information specific to the logical volume it identifies. The first pseudoname is then mapped to the target logical volume identifier.
