52 Getting Started with the McDATA Intrepid FICON Director
If Active=Saved is enabled (check mark), the IPL and the active address configuration
are maintained as identical configurations. If a new configuration is activated through
the Configure Addresses - "Active" dialog box, that configuration becomes the IPL
address configuration. If the feature is enabled, the IPL file is locked to modification
through the Configure Addresses - "Active" dialog box.
If Active=Saved is disabled (no check mark), the IPL address configuration and the
active configuration are not maintained as identical and may, in fact, be different
configurations. If the feature is disabled, you can modify the IPL configuration through
the Configure Addresses - "Active" dialog box.
6. Select a
code page from the Code Page list to determine the language for displaying port
names or the CUP name when assigned from a host. For example, if the code page for
Germany/Austria is selected and a port name is assigned in German by the host
management program, then the German language port name appears in the Product
Manager.

5.4 Building a fabric
To establish a cascaded fabric (two FICON Directors are merged together), several steps are
required. Before starting the merging process perform the following:
1. Verify that the appropriate setup has been completed according to the procedure in 5.1,
Setting up a FICON Director on page 46.
2. Double-click the first
Director, which will be part of the fabric, then click Configure,

.
3. Check the following settings as shown in Figure 5-9:
The BB_Credit can be between 1 and 60 buffers. This becomes the value for all ports,
except those configured for extended distance buffering (10-100 Km). The default
value is 16.
The R_A_TOV and E_D_TOV time-out values must be the same for both Directors,
otherwise they cannot be merged into a cascaded fabric.
McDATA Fabric 1.0 is the Interop Mode used, since a cascaded FICON configuration
requires that both Directors must be from the same vendor.
Important: If the Directors are already configured and in use, make sure that S/390
Operating Mode
is selected. The merge into a cascaded fabric can then be done
concurrent to normal operation.
