Migrating from a FICON bridge to a native FICON attachment
This section shows how to migrate from a FICON bridge to a native FICON
attachment. The FICON bridge is a feature card of the ESCON Director 9032 Model
5. The FICON bridge supports an external FICON attachment and connects
internally to a maximum of eight ESCON links. The volume on these ESCON links
is multiplexed on the FICON link. You can perform the conversion between ESCON
and FICON on the FICON bridge.
FICON bridge configuration
Figure 43 on page 76 shows an example of how to configure a FICON bridge. It
also shows an S/390 or zSeries host with two FICON channels 1 attached to two
FICON bridges 2. You can attach the ESS through the channel-path group 3 to
four ESCON links 4.
