1. A method of implementing online restriping of a volume in a storage area network, the storage area network including a fibre channel fabric, the fibre channel fabric including a plurality of ports, the method comprising:
- instantiating, at a first port of the fibre channel fabric, a first instance of the volume for enabling I/O operations to be performed at the volume;
performing restriping operations at the volume; and
enabling the first port to perform I/O operations at the volume concurrently while at least a portion of the restriping operations are being performed at the volume.

Abstract
A technique is provided for implementing online restriping of a volume in a storage area network. A first instance of the volume is instantiated at a first port of the fibre channel fabric for enabling I/O operations to be performed at the volume. While restriping operations are being performed at the volume, the first port is able to concurrently perform I/O operations at the volume.
