An administrator, in preparation for a new server with dual HBAs connected to multiple fabrics, created a new WWN zone to add a new server and storage connections to Fabric A. The administrator then c

A zoning configuration conflict would typically prevent connectivity on the misconfigured fabric rather than negating all paths across both fabrics.

Zoning configurations are specific to the World Wide Names (WWNs) of devices in a particular Fibre Channel fabric. Copying a zone designed for Fabric A to Fabric B without adapting the WWNs to Fabric B's devices will cause the zone to be ineffective or incorrect on Fabric B, resulting in paths only through Fabric A.

This scenario would occur if both Fabric A and Fabric B were correctly zoned to allow paths from the server's HBAs to the storage, which is not the case for Fabric B.

Achieving four paths would require correct zoning on both fabrics, connecting both HBAs to two storage ports each across the two fabrics, and proper WWN configuration, which is not met due to the copied zone.
