Abstract:
1. A method for configuring a data storage system, comprising: establishing a first data path between a host and a storage controller that interfaces with the host and a plurality of storage devices for storing data, wherein the host accesses the storage devices through the storage controller, wherein the host and the storage devices are in a communication zone; adding a virtualization controller to map the storage devices to a plurality of virtual volumes; establishing a second data path between the host and the storage devices through the virtual volumes, wherein the host recognizes the virtual volumes as an alternate data path to the first data path between the hosts and the storage devices; removing the first data path between the host and the storage controller in response to establishing the second data path, wherein the virtualization controller is configured without disrupting I/O operations between the host and the storage devices; and performing I/O operations between the host and the storage devices through the second data path and the virtualization controller.
