Abstract:
1. A method of managing a migration of a data set from at least one first storage location to at least one second storage location, wherein read requests to the data set from at least one application program executing on a computer system initially are serviced from the at least one first storage location, wherein the computer system comprises at least one storage system that comprises the at least one first storage location and the at least one second storage location, the method comprising acts of: (A) copying the data set from the at least one first storage location to the at least one second storage location under the control of a data mobility agent that is external to the at least one storage system and uses a transfer vehicle that reads the data set from the at least one storage system that comprises the at least one first storage location to at least one intermediate component and writes the data set from the at least one intermediate component to the at least one storage system that comprises the at least one second storage location; (B) after completion of the act (A), modifying at least one aspect of the computer system so that read requests to the data set are serviced from the at least one second storage location and not from the at least one first storage location to achieve the migration of the data set from the at least one first storage location to the at least one second storage location; and (C) after completion of the act (B), undoing the migration by modifying the at least one aspect of the computer system so that read requests to the data set are again serviced from the at least one first storage location and not from the at least one second storage location.
