5. Choose one of the following options from the 256 Area Assignment list:
• Disabled—select to disable the 256 Area Assignment addressing mode.
Disabling the 256 Area Assignment mode assigns an area to every port with no imposed
limit. This is the default.
• Zero Based Area Assignment—select to use zero based area assignment.
Zero Based Area Assignment mode assigns areas as ports are added to the partition,
beginning at area zero. This mode allows FICON customers to make use of the upper ports
of a high density blade; but this mode may not be compatible with domain,index zoning in
InteropMode 2, because M-EOS switches are not capable of handling indexes greater than
255.
• Port Based Area Assignment—select to use port based area assignment.
Port Based Area Assignment mode matches the port index to the area assignment. You
cannot use high density blades if you select this option.
6. Click OK if you want to proceed after reading the warning and bulleted items.
7. A warning message is displayed explaining that SCC and DCC policies will be created and
activated on the fabric. Click Yes to continue.
If configuration is successful, a confirmation message is displayed.
If FMS Mode was selected, each switch is checked for a CUP license. Any switches that do not
have a CUP license are listed, with a reminder that a CUP license is necessary to communicate
with the fabric management server.
Merging two cascaded FICON fabrics
If you want to join two cascaded FICON fabrics, they must be merged. If the distance between
fabrics is 10 km or more, an Extended Fabrics license is required, and an extra step is required to
configure the connection as a long distance connection. To successfully configure a long distance
connection, use the same E_Ports and cable distance values used when configuring Extended
Fabrics. For long distance connections, it is recommended that you create the Extended Fabrics
configuration first, have an active connection, and have the E_port and cable distances values
ready before you merge the fabrics.
1. Select Configure > FICON > Merge Fabrics.
The Overview screen of the Cascade FICON Fabrics Merge wizard is displayed.
2. Click Next.
The Select fabrics screen is displayed.
3. Select the two fabrics you want to merge under Available Fabrics, and click the right arrow to
move them to Selected Fabrics. You may do this one fabric at a time, or select both by pressing
CTRL and then clicking each fabric.
NOTE
All switches in a fabric must be running OS version 5.2 or later and much be reachable. If a
Fabric OS version earlier than version 5.2 is present in the fabric, the fabric is not listed.
