Having a problem sharing storage with CASO.

This is how my environment is setup:

Site#1 - CASO installed on Backup Exec 2012 server

Site#2 - MMS installed on Backup Exec 2012 server.

Site#3 - MMS installed on Backup Exec 3600 appliance

Site#4 - MMS installed on Backup Exec 3600 appliance

For disaster recovery purposes, I want to be able to replicate deduplicated data to either of my Backup Exec 3600 appliances or another MMS.  For instance, when I go to share one of my 3600 applicances as shared storage, it is saying that none of my other servers do not have the deduplication option installed, when they do.  The 3600 applicances come bundled with the deduplication option.
