There are limitations in switch zoning for the Lenovo Storage V series and EMC VMAX systems.
The Lenovo Storage V series switch zone must include at least one target port on two or more Fibre Channel adapters to avoid a single point of failure.
The EMC VMAX must be configured to present logical units (LUs) to all Lenovo Storage V series initiator ports that are in the fabric zone.
Only Lenovo Storage V series initiator ports that are LUN-masked on the EMC VMAX controller should be present in the fabric zone.
You can connect a maximum of 16 EMC VMAX ports to the Lenovo Storage V series system. There are no further special zoning requirements. Configurations that are set up to adhere to the requirements that are described in previous Lenovo Storage V series releases are also supported, but should not be followed for new installations.
