The Check merge screen displays.
A Status details table shows progress through merge check points. A rotating arrow under
Status indicates a Merge check step is in progress. A blue check mark indicates successful
completion of that Merge check. A red stop sign indicates a failed step. If the configuration is
successful, all configuration items have blue check marks.
The Configure long distance (optional) dialog box displays. If the distance between the merged
fabrics is 10 km or greater, you must configure the connection as a long distance connection.
Selecting a distance invokes an algorithm to compute the required number of BB Credits
available to the port. The longer the link, the greater latency, resulting in the potential for more
outstanding frames in the link, and the need for more BB credits. FICON may require more BB
credits than the algorithm provides, and it is a good practice to specify a distance that is longer
than the actual distance to be sure enough BB credits are allocated.
