Access Control in FICON

FIGURE 6 Simple cascaded zoning

Figure 7 illustrates the multiple zoning concepts that can be used to restrict traffic. In Figure 7, any

host channel at the Backup Site (connected to Director 11 or Director 12) can connect to the

backup tape contained with the same zone. Notice that no more than a single hop is ever allowed

and only Channel Path Identifiers (CHPIDs) 79 and 7A on the Primary Site can connect to the

backup tape. Furthermore, CHPIDs 79 and 7A can only connect to the backup tape at the Backup

Site.

NOTE

Zoning does not replace the need to set up the connectivity from the host to storage control units in

the HCD or IOCP.

For more information on zoning, refer to the Fabric OS Administrator’s Guide.
