Physical Planning Considerations

4. Click OK to save the path configuration and close the dialog box.
Activating a preferred path can result in receipt of out-of-order frames (especially
in FICON environments) if the path differs from the current path, if input and
output (I/O) are active from the source port, and if congestion is present on the
current path.
To avoid problems in FICON environments, vary associated channel path
identifiers (CHPIDs) temporarily offline, configure the preferred path, and vary
the CHPIDs back online.
Zoning
Directors and switches support a user configuration that partitions attached
devices into restricted-access groups called zones. Devices in the same zone can
recognize and communicate with each other through switched port-to-port
connections. Devices in separate zones cannot recognize name server or route
table information and therefore cannot communicate with each other. Figure 60
illustrates a Director 2/64 with three zones (four devices per zone).
Figure 60: Product Zoning
Zoning is enabled and enforced by one of the following processes:
