21 Cascaded FICON fabric merge

NOTE

To enable DLS, all switches in the fabric must be 8 Gbps or faster and running Fabric OS 6.3 or later.

•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.

The cascaded FICON fabrics merge wizard performs the following operations to avoid Active Directory (AD), Access Control List (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 can take a long time; for example, in a 50-switch fabric, this operation can 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

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

Cascade FICON fabrics merge 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.
