Switch zoning limitations for NetApp FAS systems
There are limitations in switch zoning for SAN Volume Controller clustered systems and NetApp FAS systems.
Fabric zoning
The SAN Volume Controller 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 SAN Volume Controller system and other hosts. However, you must define separate initiator groups (igroups) for the SAN Volume Controller initiator ports and the host ports.
Host splitting
A single host cannot be connected to both the SAN Volume Controller 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 SAN Volume Controller system
under the following conditions:
- Target ports are dedicated to each host or are in a different igroup than the SAN Volume Controller system
- LUNs that are in the SAN Volume Controller system igroup are not included in any other igroup
