Switch zone limitations for HDS Lightning

Switch zoning

The HDS Lightning 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 SAN Volume Controller system using the same logical unit number (LUN).
