Switch zoning limitations for the EMC VMAX

There are limitations in switch zoning for the IBM Spectrum Virtualize™ and EMC VMAX systems.

Switch zoning

The IBM Spectrum Virtualize 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 IBM Spectrum Virtualize initiator ports that are in the fabric zone.

Only IBM Spectrum Virtualize initiator ports that are LUN-masked on the EMC VMAX controller should be present in the fabric zone.

Note: An EMC VMAX system presents itself to the IBM Spectrum Virtualize clustered system as one WWNN with a minimum of two and a maximum of 16 WWPNs supported.

Connecting to the SAN

You can connect a maximum of 16 EMC VMAX ports to the IBM Spectrum Virtualize system. There are no further special zoning requirements. Configurations that are set up to adhere to the requirements that are described in previous IBM Spectrum Virtualize releases are also supported, but should not be followed for new installations.
