Switch zoning limitations for the Hitachi TagmaStore AMS 2000 family of systems

Switch zoning

Members of the Hitachi TagmaStore AMS 2000 family of systems present themselves to the SAN Volume Controller clustered system as separate storage systems for each port zoned to the SAN Volume Controller system. For example, if one of these storage systems has four ports zoned to the SAN Volume Controller system, each port appears as a separate storage system rather than one storage system with four WWPNs. In addition, a given logical unit (LU) must be mapped to the SAN Volume Controller system through all storage system ports that are zoned to the system that use the same logical unit number (LUN).
