Cascaded FICON fabric merge

Merging two cascaded FICON fabrics
NOTE
If you receive a 'FICON not supported on switch' error, refer to FICON troubleshooting for a list of
possible causes.
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 or right-click a fabric in the product tree and select
FICON > Merge Fabrics.
The Overview screen of the Cascade FICON Fabrics Merge wizard displays.
NOTE
This dialog wizard is only available for Fabric OS products.
2. Click Next.
The Select fabrics screen displays.
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 5.3 or later and much be reachable. If a
Fabric OS version earlier than version 5.3 is present in the fabric, the fabric is not listed.
NOTE
Switches running Fabric OS 6.3 or earlier cannot be merged with switches running
Fabric OS 6.4 or later.
NOTE
For 8 Gbps switches, all switches in the fabric must be 8 Gbps or faster. 8 Gbps switches
cannot be merged with switches that have SFPs with a speed less than 8 Gbps.
4. Click Next.
The Set up merge options screen displays.
5. Select FMS Mode to manage the fabric by a host-based management program using FICON
CUP protocol. Note that you cannot enable FMS Mode on switches running Fabric OS 7.0 or
later unless they have an active CUP license.
6. Select a secondary fabric where AD, ACL, and zone databases, if defined, will be cleared.
7. Read the bulleted list of actions so you understand the actions that are taken to avoid conflicts
when the fabrics are merged.
