Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

Claims
We claim:

1. A data storage device comprising:
a hypervolume accessible by two or more servers operating on two or more data storage systems;

a first physical volume located at a first data storage system and associated with the hypervolume; and

a second physical volume located at a second storage system
and associated with the hypervolume;

wherein the hypervolume directs input/output (I/O) from the
servers to a primary physical volume comprising one of the first and second physical volumes, and further wherein the primary physical volume may be changed, transparently to the servers, to the other of the first and second physical
volume.

2. A method for moving operation of a storage device from one data storage location to a second data storage location comprising:
creating a hypervolume accessible by two or more servers
operating at two or more data storage locations;

associating a primary physical volume located at one of the two or more data storage locations with the hypervolume;

associating a secondary physical volume located at another of the two or more data storage locations with the
hypervolume;

using the hypervolume to redirect input/output (I/O) from the servers from the primary physical volume to the secondary physical volume, such that the redirecting of the I/O from the servers is transparent to the servers.
