Sharing an IBM DS5000, IBM DS4000, or IBM DS3000 systems between a host and a node

You can share an IBM® DS5000™, IBM DS4000®, or IBM DS3000 system between a host and a node.

The IBM DS5000, IBM DS4000, and IBM DS3000 function that is 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 node.

Note: The node partition must either contain all the host ports of the node system that are connected to the SAN or the host ports that are zoned to have access to the storage system ports. For example, configure so that each host bus adapter (HBA) port on the node is able to see at least one port on storage system A and one port on storage system B.
