Chapter 5. Configuring the FICON Director 53
Figure 5-9 Verify settings of FICON Directors
We used the default values for our configuration. However, the BB_Credit was changed for
certain ports when we enabled long distance buffering, as shown in 5.5.3, “Configuring a
port” on page 61.
4. Verify/apply settings on the second Director that will be included in the fabric.
If you wish to use Switch Binding, ensure all the devices are attached to the Directors. The
devices (WWNs) are automatically placed in the Switch Binding membership list when
Enterprise Fabric Mode is enabled. Switch Binding is described under 5.4.1, “Switch Binding”
on page 56.
5. Identify and connect the ISLs based on your configuration requirements.
Activating Enterprise Fabric Mode enables the features (Fabric Binding and Insistent
Domain ID), necessary to support FICON cascaded Directors.
6. Select
Fabrics from the Products view screen and choose Enterprise Fabric Mode as
shown in Figure 5-10.
Note: Blocking the E_Ports used for ISLs is recommended when connecting the ISLs
between the Directors. This ensures that the fabric remains stable during the cabling
process. Unblock the ports one-by-one after connecting the cables, and check for errors
in the logs (see “Fabric log” on page 42, “Event log” on page 42, and “Link incident log”
on page 43).
