HWNLM0563W A zone unnecesary_zone was not created, because the host already has connectivity to the storage system using existing_zone.

Explanation

When automatic zoning is enabled, new zones might be created during provisioning to connect the server or hypervisor to the storage system. New zones are created only if the server or hypervisor does not have connectivity with the storage system. In this case, a new zone was not needed because another zone between the same ports already exists in the active zone set.
