All,

       I'm going to explain in detail what i'm trying to do and what my issue is:

Scenario:

              I have a cisco emc mds 2916ia switch in datacenter 1 connecting to a MCdata Ds-24m2 san switch that connects to a host.  In datacenter 2 I have a Mcdata ds-24m2 san switch connecting to a cisco emc dms 2916ia switch.  These two datacenters are connected by an fcip tunnel between the two cisco switches.  My goal is to be able to see the host in datacenter 1 from the san switch in datacenter 2.  This is suppose to be possible from what I was told.

            Datacenter 1 connections:

               1.) MDS 2916i gig0/1 connects to Core switch port 1 which is connecting to datacenter 2 through fcip tunnel on datacenter 2 Mds2916i port 1.

               2.) MDS 2916i port 1 (e port) goes to Mcdata ds-24m2 san switch port 1 (e port)

               3.) Host (f port) connects to Mcdata ds-24m2 san switch port 2 (e port)

             Datacenter 2 connections:

             1.) MDS 2916i port 1 (e port)  goes to Mcdata ds-24m2 san switch port 1 (e port)

             2.) No host (trying to view host in datacenter 1 from san switch)

             3.) MDS 2916i gig0/1 connects to core port 1 which is connecting to datacenter 1 through fcip tunnel on datacenter 1 Mds2916i port 1.

Issue:

                          I cannot zone (MDS 2916i port 1 (e port)/Mcdata ds-24m2 san switch port 1 (e port)) ----> to host. I get zone merge failure from the cisco switch port.

Please help.  Thank you.
