For devices to be able see each other, connect, create sessions with one another, and communicate, both ports need to have a common zone membership. Single initiator zoning is recommended. A zone is created for the HBA and storage array Target ports are added. If the same HBA accesses a tape device then a second zone is created for the same HBA and associated tape device port This type of zoning is very restrictive - if a device is moved to a different port on the switch, it can lose. In storage networking, Fibre Channel zoning is the partitioning of a Fibre Channel fabric into smaller subsets to restrict interference, add security, and to simplify management. Creates a barrier between different network environments. A zone set is a collection of zones which in turn have individual members in them.
