The following illustration shows connections and zoning for sharing an FC initiator port with target ports on different storage arrays.

The solid lines in the following illustration show the connections from the FC initiator ports on system vs1 and the dashed lines show the connections from the FC initiator ports on system vs2.

The following table shows the 1:1 zoning definitions for the example of one FC initiator port sharing multiple target ports on different storage arrays.

This configuration can be used only with storage arrays whose LUN masking, presentation, or host group capability allows for different LUN group presentations to the same FC initiator based on the target port being accessed.

Some storage arrays can present different sets of logical devices to an FC initiator based on the target port being accessed. These types of storage arrays allow the same FC initiator to be in multiple host groups. On storage arrays with this capability, it is possible for each FC initiator to access multiple array target ports on the same storage array, with each target port presenting a different LUN group to the FC initiator. Check your storage array documentation to determine whether your storage array allows the same FC initiator to be in multiple host groups.

The following illustration shows connections and zoning for sharing an FC initiator port with multiple target ports on the same storage array. In this example, zoning definitions are configured as 1:1, that is, one FC initiator to one target port.

The solid lines in the following illustration show the connections from the FC initiator ports on system vs1 and the dashed lines show the connections from the FC initiator ports on system vs2. Two LUN groups are required for this configuration.

The following table shows the 1:1 zoning definitions for the example of one FC initiator port sharing multiple target ports on the same storage array.
