Sharing the HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, or HDS TagmaStore WMS between a host and the IBM Spectrum Virtualize
You can share the HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore Workgroup Modular Storage (WMS) systems between a host and the IBM Spectrum Virtualize™ clustered system, with certain restrictions.
The following restrictions apply:
- The same host cannot be connected to both the IBM Spectrum Virtualize system and an HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, or HDS TagmaStore WMS at the same time because Hitachi Dynamic Link Manager (HDLM) and the subsystem device driver (SDD) cannot coexist.
- For the HDS Thunder 9200, a target port cannot be shared between a host and the IBM Spectrum Virtualize system. If a target port is used by the IBM Spectrum Virtualize system, it cannot be present in a switch zone that allows a host to access the port.
- Logical units (LUs) cannot be shared between a host and the IBM Spectrum Virtualize system. The Thunder 9200 must be set into M-TID M-LUN mode and Mapping Mode must be enabled on Thunder 95xx. No LU can have a LUN number that is associated with a port that is zoned for host use while also having a LUN number that is associated with a port that is zoned for the IBM Spectrum Virtualize system.
