Abstract:
An identification request is received from a host device. A virtual address that identifies at least the first device and a second device is determined. The first device and the second device are coupled together to form a plurality of redundant paths between the host device and a target device. A plurality of target ports associated with the target device are determined. A single virtual target port address is assigned to the plurality of target ports associated with the target device. A first of the plurality of redundant paths between the host device and the target device is designated as an active path. The first of the plurality of redundant paths between the host device and the target device is associated with a first of the plurality of target ports. The virtual address and the virtual target port address are transmitted to the host device.
