23 Cascaded FICON fabric merge Cascaded FICON fabric merge The Management application provides a wizard to help you merge two fabrics for cascaded FICON. Note that merging two cascaded FICON fabrics may be disruptive to current I/O operations in both fabrics, as it needs to disable and enable the switches in both fabrics. The merge process will not make any configuration changes on the primary (production) fabric that are disruptive. NOTE It is recommended that you run a configuration backup on all switches before performing the fabric merge. This helps you to revert back the switch configurations later. The cascaded FICON fabrics merge wizard performs the following operations: • Checks the primary and secondary fabrics for any merge issues. • Configures High Integrity Fabric Configuration (HIFC) on the seed switch of the primary and secondary fabric. - SCC Policy will be created or modified to limit connectivity to switches from both fabrics. - Configures Fabric Wide Consistency Policy (FWCP) on both fabrics. - FWCP is configured in tolerant mode for SCC for an FCR fabric. • Enables Port Based Routing (PBR) on all switches in the secondary fabric if all the switches in the primary fabric are found to be enabled for PBR. Note that a mixed policy of Exchanged Based Routing (EBR) and PBR cannot be enabled on a fabric. • Enables Exchange-Based Routing (EBR) on all switches in the secondary fabric if all switches in the primary fabric are enabled for EBR. Note that EBR requires that switches operate at 8 Gbps or greater with Fabric OS 6.4 or later. If all the EBR-enabled switches in the primary fabric are found to meet these requirements and a switch in the secondary fabric does not meet these requirements, an error message displays. Note that a mixed policy of EBR and PBR cannot be enabled on a fabric. • Primary fabric switches will not be enabled for DLS, In-Order Delivery (IOD), insistent domain ID flag (IDID), and APT. - Dynamic Load Sharing (DLS) will be enabled on switches in the secondary fabric that are operating at 8 Gbps or greater and are running Fabric OS 6.3 or later. NOTE To enable DLS, all switches in a fabric should have equal Fabric OS levels. - You can optionally select to enable IOD on switches in the secondary fabric. - Primary fabric switches will not be disturbed for disruptive operations, such as IDID and APT. Instead, all primary fabric switches will be validated for current routing policies and the same policies will be enabled on all the secondary fabric switches. • (Optional) Turns on FICON Management Server (FMS) mode on all switches. If some switches already have FMS mode enabled, it is re-enabled. - If switches are running Fabric OS 7.0 and later, FMS will not be enabled on switches that do not have an active CUP license. - If switches are running Fabric OS earlier than 7.0 and not have a CUP license, after successful configuration, you can access the Port Connectivity (Allow/Prohibit) matrix, but the host system cannot communicate with the FICON Management Server unless you install a CUP license. If a CUP license is later installed on these switches, then FMS mode must be re-enabled on these switches. 716 Brocade Network Advisor IP User Manual 53-1002168-01
