ABSTRACT:
Methods and apparatus for migrating a logical object. In one embodiment, a migration is performed by automatically determining the source location(s) of the logical object, moving the data stored therein to a target location while maintaining the availability of the data at the source location to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In another embodiment, a migration is performed by automatically provisioning target location(s) to store a logical object, moving the data in the logical object to the target location(s) while maintaining its availability to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In a further embodiment, a migration is performed by moving the data within a logical object from a source logical volume to a target logical volume, automatically servicing access requests from an application program at the target logical volume after moving the data, and retiring the source logical volume.
