I've previously worked on a the Nexus line of products for SAN switching, but now looking at a configuration requirement for a pair of MDS switches. The switches will be in 2 separate locations and connected to each other via fiber interconnects. MDS-A will connect to multiple hosts and a local SAN. MDS-B will connect to multiple local hosts as well as a local SAN. The goal is for devices connected to MDS-A to see the storage connected locally to MDS-B and vice-versa. MDS-A is configured already for the hosts local (I can post the configuration if helpful), but I'm having difficulty w/ what is required to get the rest of it working. If there is a good whitepaper or link to read that outlines this that would be very helpful.

So I think I have it configured correctly. Did all my zoning configuration on switch 1. Connected the 2 switches but the interfaces stay at Initializing. The switches are both the same model 9132s running the same firmware. Here is the configuration of each:
HQ-MDS01# sh vsan
vsan 1 information
name:VSAN0001 state:active
interoperability mode:default
loadbalancing:src-id/dst-id/oxid
operational state:down
vsan 10 information
name:storage-a state:active
interoperability mode:default
loadbalancing:src-id/dst-id/oxid
operational state:down
vsan 4079:evfp_isolated_vsan
vsan 4094:isolated_vsan
interface fc1/16
switchport mode F
switchport trunk allowed vsan 10
switchport trunk mode auto
port-license acquire
no shutdown
-------------------------------------------------
DC-MDS02# sh vsan
vsan 1 information
name:VSAN0001 state:active
interoperability mode:default
loadbalancing:src-id/dst-id/oxid
operational state:down
vsan 10 information
name:storage-a state:active
interoperability mode:default
loadbalancing:src-id/dst-id/oxid
operational state:down
vsan 4079:evfp_isolated_vsan
vsan 4094:isolated_vsan
interface fc1/16
switchport speed auto
switchport mode F
switchport trunk allowed vsan 10
switchport trunk mode auto
port-license acquire
no shutdown
I tried hard coding the speed at 32000 as well (both switches have a DS-SFP-FC32G-L installed) but no change. Logs don't appear to include anything with respect to the interface.
Changing both ports to mode E seems to have fixed the issue.

So i was able to get this configured and working as far as I can tell. I connected devices to 2 of the MDS and confirmed I'm able to see them attached and the zoneset looking correct when doing a "show zoneset active". I noticed that when I went to an activate of my zoneset on 2 of the 4 9132s they displayed a message that the zoneset wasn't present. Did I forget to do something? I thought the zoneset would be configurable on any of the 4 9132s (2 in each vsan).
