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