FICON configuration example for a zSeries or S/390 host

The following figure provides a FICON configuration example for a zSeries or S/390 host that

illustrates how to remove the ESCON paths.

The S/390 or zSeries host has four ESCON channels connected to two ESCON directors. The S/390

or zSeries host system also has two FICON channels.

Figure 19 Non-Disruptive ESCON Channel Removal

You can remove the ESCON adapters non-disruptively from the storage unit while I/O continues on

the FICON paths. By changing the channel-path group definition to include only the FICON director

paths, you can complete the migration to the storage unit with two FICON adapters. You can also

retain the ESCON channels on the S/390 or zSeries host system so you can access other ESCON

controllers. You also can keep the ESCON adapters installed in the storage unit to connect to other

S/390 or zSeries hosts.
