Sharing an IBM DS5000, IBM DS4000, or IBM DS3000 systems between a host and SAN Volume Controller

You can share an IBM® DS5000™, IBM DS4000®, or IBM DS3000 system between a host and a SAN Volume Controller clustered system.

The IBM DS5000, IBM DS4000, and IBM DS3000 function known as partitioning must be used to separate groups of logical units that are directly attached to hosts or groups of hosts from the logical units that are accessed by the SAN Volume Controller system.
Note: The SAN Volume Controller partition must either contain all the host ports of the SAN Volume Controller system that are connected to the SAN or are zoned to have access to the storage system ports. For example, configure so that each SAN Volume Controller host bus adapter (HBA) port on SAN Volume Controller are able to see at least one port on storage system A and one port on storage system B.
