Cascaded FICON fabric merge
23
• (Optional) Configures long distance settings on selected ports of primary and secondary
fabrics (requires Extended Fabric license).
NOTE
If the distance between the merged fabrics is 10 km or greater, you must configure the
connection as a long distance connection.
The cascaded FICON fabrics merge wizard performs the following operations to avoid AD, ACL, and
zone database merge conflicts between the two fabrics:
• Clears Admin Domain, Access Control Lists (ACLs), and zone databases, if they exist, from the
secondary fabric that you select within the wizard.
NOTE
Clearing the ACL database in a large fabric might take a long time; for example, in a 50-switch
fabric, this operation might take from 30 minutes to 1 hour.
• Sets the default zoning configuration on the secondary fabric to match the default zoning
status of the primary fabric.
• Modifies ACL Policy on the secondary fabric to match the primary fabric parameters, including
Accept Distribution and FWCP.
• Sets FWCP in strict mode for SCC for the primary fabric.
• Sets FWCP in tolerant mode for the Fibre Channel Routing (FCR) fabric.
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.
The Overview screen of the Cascade FICON Fabrics Merge wizard displays.
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.
