Switch zoning limitations for Pillar Axiom systems
There are limitations in switch zoning for IBM Spectrum Virtualize™ clustered systems and Pillar Axiom systems.
Fabric zoning
The IBM Spectrum Virtualize switch zone must include at least one target port from each Pillar Axiom controller to avoid a single point of failure.
Target port sharing
Target ports can be shared between the IBM Spectrum Virtualize system and other hosts.
Host splitting
A single host cannot be connected to both the IBM Spectrum Virtualize system and the Pillar Axiom system to avoid the possibility of an interaction between multipathing drivers.
Controller splitting
Pillar Axiom system LUNs that are mapped to the IBM Spectrum Virtualize system cannot be mapped to other hosts. Pillar Axiom system LUNs that are not mapped to the IBM Spectrum Virtualize system can be mapped to other hosts.
