Reversing a communication path between storage devices

A method of managing volumes on storage devices, comprising:

• receiving a command requesting reversal of a communication path between a first volume on a first storage device and a second volume on a second storage device;
• suspending communication between the first and second volumes while maintaining operations for other volumes of the storage devices;
• causing the first volume to change from a source volume to a destination volume without destroying the first volume;
• causing the second volume to change from a destination volume to a source volume without destroying the second volume;
• and
• resuming communication between the first and second volumes.

A computer program product that reverses a communication path between a first volume on a first storage device and a second volume on a second storage device, comprising:

• executable code that suspends communication between the first and second volumes while maintaining operations for other volumes of the storage devices;
• executable code that causes the first volume to change from a source volume to a destination volume without destroying the first volume;
• executable code that causes the second volume to change from a destination volume to a source volume without destroying the second volume;
• and
• executable code that resumes communication between the first and second volumes.
