There are limitations in switch zoning for the SAN Volume Controller and the HDS Lightning systems.
The HDS Lightning systems present themselves to a SAN Volume Controller cluster as separate controllers for each port zoned to the SAN Volume Controller. For example, if one of these storage systems has 4 ports zoned to the SAN Volume Controller, each port appears as a separate controller rather than one controller with 4 WWPNs. In addition, a given logical unit (LU) must be mapped to the SAN Volume Controller through all controller ports zoned to the SAN Volume Controller using the same logical unit number (LUN).
