Reversing a communication path between storage devices
First Claim
1. A method of reversing a communication path between a first volume on a first storage device and a second volume on a second storage device, comprising:
- 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.

Abstract
Reversing a communication path between a first volume on a first storage device and a second volume on a second storage device includes 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. Causing the first volume to change from a source volume to a destination volume may include modifying a table of the first storage device. Causing the second volume to change from a source volume to a destination volume may include modifying a table of the second storage device.
