Switch zone limitations for HDS Lightning

Switch zoning

The HDS Lightning systems present themselves to the IBM Spectrum Virtualize clustered system as separate storage systems for each port zoned to the IBM Spectrum Virtualize system. For example, if one of these storage systems has four ports zoned to the IBM Spectrum Virtualize 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 IBM Spectrum Virtualize system through all storage system ports that are zoned to the IBM Spectrum Virtualize system using the same logical unit number (LUN).
