Restrictions on multiple replicas in a LAN

There are restrictions on how you can create multiple replicas in a LAN that impact how you can design your replica architecture when using MultiSite for interoperability.
Attention: Do not use MultiSite to create multiple copies of a VOB in a single ClearCase® region. Because the VOB UUID is identical for all replicas in a VOB family and is stored in many structures in a VOB, there is no way to make the copy of the VOB unique. Creating and mounting multiple copies of a VOB in a single region causes clearmake and views to exhibit unpredictable behavior, may cause data loss, and is not supported.
