Sharing the HDS Lightning 99xxV between a host and the Storwize V3700
There are restrictions for sharing an HDS Lightning 99xxV between a host and the Storwize® V3700 clustered system.
Sharing ports
The HDS Lightning 99xxV can be shared between a host and the Storwize V3700 system under the following conditions:
- The same host cannot be connected to both the Storwize V3700 system and an HDS Lightning at the same time because the Hitachi HiCommand Dynamic Link Manager (HDLM) and the subsystem device driver (SDD) cannot coexist.
- A controller port cannot be shared between a host and the Storwize V3700 system. If a controller port is used by the Storwize V3700 system, it must not 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 Storwize V3700 system.
