Switch zoning limitations for NetApp FAS systems

There are limitations in switch zoning for IBM Spectrum Virtualize™ clustered systems and NetApp FAS systems.

Fabric zoning

The IBM Spectrum Virtualize switch zone must include at least one target port from each filer to avoid a single point of failure.

Target port sharing

Target ports can be shared between the IBM Spectrum Virtualize system and other hosts. However, you must define separate initiator groups (igroups) for the IBM Spectrum Virtualize initiator ports and the host ports.

Host splitting

A single host cannot be connected to both the IBM Spectrum Virtualize system and the NetApp FAS to avoid the possibility of an interaction between multipathing drivers.

Controller splitting

You can connect other hosts directly to both the NetApp FAS and the IBM Spectrum Virtualize system under the following conditions:
  • Target ports are dedicated to each host or are in a different igroup than the IBM Spectrum Virtualize system
  • LUNs that are in the IBM Spectrum Virtualize system igroup are not included in any other igroup
