I have connected brocade 300 to cisco MDS 9222i via 4 Gig FC interface. By connection diagram is as follows brocade 300 -> cisco MDS 9222i -> cisco MDS 9222i -> brocade 300. Two cisco MDS is connected to each other through 1 Gig Ethernet, FCIP tunnel is also being created using this 1 Gig Ethernet interface. Storage box is connected to the brocade switches at both ends. I want to test the remote volume mirroring between both storage boxes, for this I need to see both brocade switches under single fabric so as to zone their interface under single zone. Anybody can help me in this with cisco end & brocade end configuration?
