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. 56 Linux operations

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.

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.
