For example, Fibre Channel routing allows you to share tape drives across multiple fabrics without the administrative problems, such as change management, network management, scalability, reliability, availability, and serviceability that might result from merging the fabrics. Fibre Channel routing lets you create logical storage area networks (LSANs) that can span fabrics. These LSANs allow Fibre Channel zones to cross physical SAN boundaries without merging the fabrics while maintaining the access controls of zones. NOTE When the Virtual Fabrics capability is enabled, FCR operations are allowed only on the base switch. EX_port configurations are supported only on the base switch. Also, because FC ports on 7500 extension switches cannot be added to a base switch, EX_port configuration for FC ports on 7500 extension switches is blocked.
