Switch zoning has limitations for the system and Pillar Axiom systems.
The system's switch zone must include at least one target port from each Pillar Axiom controller to avoid a single point of failure.
Target ports can be shared between the system and other hosts.
A single host cannot be connected to both the system and the Pillar Axiom system to avoid the possibility of an interaction between multipathing drivers.
Pillar Axiom system LUNs that are mapped to the system cannot be mapped to other hosts. Pillar Axiom system LUNs that are not mapped to the system can be mapped to other hosts.
