But this one doesn't have any issues, Controller A is connected to Port 0 of Fiber Card 1 and Controller B is connected to Port 1 of Fiber Card 2 but there is a switch in between them and there is zoning.

I will zone the switch as IBMTECH suggested and try and post the details...

If anyone know how to solve this issue, please post.
thanks

                  o  Device name

                  o  Software version (not supported and prints as 0)

                  o  Drive id number (not supported and prints as 0)

                  o  Device blocks per cylinder

                  o  Device bytes per block

                  o  Number of device partitions with a block size greater than zero
