Figure 3-9 Configuration example of zoning
In this example, we have several LPARs with paths to different CUs via two FICON Directors.
Each LPAR must get access only to a specific CU, and no access to CUs belonging to other
partitions.
To prevent intended access by others, we have grouped the ports belonging to the path
between an LPAR and CU into a zone. There are three zones defined as follows:
Zone1 Zone1 has all ports for the path between LPAR1 and CU1, which are
Ports 05 and 14 in SW61.
Zone2 Zone2 has all ports for the path between LPAR2 and CU2, which are
port 11 in SW61 and port 10 in SW62.
Zone3 Zone3 has all ports for the path between LPAR3 and LPAR4 and CU3
which are port 0D, 11 and 08 in SW62
All three zones are added into Zoneset1.
The link between both switches (ISL) is transparent in the path between LPAR2 and CU2.
3.7 Cables and connectors
Considerations for fiber optic cables and connectors depend on the environment. If there are
existing fiber optic cables in the environment, consider about reusing these cables rather than
installing new.
