Sharing the HDS Lightning 99xxV between a host and the system

There are restrictions for sharing an HDS Lightning 99xxV between a host and the system.

Sharing ports

The HDS Lightning 99xxV can be shared between a host and the system under the following conditions:
  • The same host cannot be connected to both the 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 system. If a controller port is used by the 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 system.

Supported topologies

For the system, you can connect a maximum of 16 HDS Lightning ports to the system without any special zoning requirements.
