Switch zoning limitations for Xiotech ISE storage systems
Limitations exist in switch zoning for IBM Spectrum Virtualize™ clustered systems and the Xiotech ISE storage system.
Fabric zoning
To avoid a single point of failure, the IBM Spectrum Virtualize switch zone must include both target ports from each Xiotech ISE 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 Xiotech ISE system.
Controller splitting
Xiotech ISE system logical unit numbers (LUNs) that are mapped to the IBM Spectrum Virtualize system cannot be mapped to other hosts. Xiotech ISE system LUNs that are not mapped to the IBM Spectrum Virtualize system can be mapped to other hosts.
