There are limitations in switch zoning for SAN Volume Controller clusters and NetApp FAS systems.
The SAN Volume Controller switch zone must include at least one target port from each filer to avoid a single point of failure.
Target ports can be shared between the SAN Volume Controller cluster and other hosts. However, you must define separate initiator groups (igroups) for the SAN Volume Controller initiator ports and the host ports.
A single host cannot be connected to both the SAN Volume Controller cluster and the NetApp FAS to avoid the possibility of an interaction between multipathing drivers.
