Connecting cascaded FICON fabrics over FCIP
This section provides a basic guide of IP best practices for connecting cascaded FICON fabrics over
an IP network through FCIP and merging the fabrics. Included are planning considerations, steps
for configuring an IP link between two Extension Switches and merging them into one fabric, and
steps for configuring DWDM links to use R_RDYs.
IP best practice for connecting the fabrics is to perform the following steps in order:
1. Configure all IP tunnels and circuits between the fabrics.
2. Merge the FICON fabrics.
NOTE
Merging two cascaded FICON fabrics may be disruptive to current I/O operations in both
fabrics, as it needs to disable and enable the switches in both fabrics. The merge process will
not make any configuration changes on the primary (production) fabric that are disruptive.
3. Configure FICON Emulation features, if applicable.
NOTE
Consult with a qualified support specialist before implementing the FICON Acceleration
feature.
The following procedures apply to configuring an IP connection between two Extension Switches or
Blades, then merging the fabrics to which they belong. Before fabrics are linked and merged, the
individual fabrics would appear as in
Figure 429 .

After creating an IP link between sw31 and sw30, then merging the Test_FID_02 fabric is into the
FID_02_Fabric, the merged fabric will look similar to that shownin
Figure 431 .
