Adding Devices to Multiple Zones
In the previous example, each host only communicates with the devices in the same zone as the
host. However, there may be situations in which hosts in separate zones need to share devices.
When this situation occurs, use overlapping zones to share the devices between the hosts. Figure
3-15 depicts this type of zoning configuration.
In Figure 3-15, zone 1 includes ports 1, 3, and 4, while zone 2 includes ports 2, 4 and 5. Port 4 is
in both zones. Devices on ports 1, 3, and 4 have direct access to each other and devices on ports
2, 4, and 5 have direct access to each other, but devices 1 and 3 are separated from devices 2
and 5. The device on port 4 has direct access to all the devices on ports 1, 2, 3, and 5.
To add storage devices to multiple zones:
1. Select the appropriate zones for each port.
2. Ensure the Zoning Active check box is selected.
