Zoning Concepts and Guidelines Configuration naming is more flexible. In general though there should be one configuration named "PROD fabricname". Fabricname is the name that the fabric has been designated. The purpose of the PROD configuration is to easily identify the configuration that can be implemented and provide the most generic services. If other configurations are used for specialized purposes, the names such as "BACKUP_A", "RECOVERY_2", "TEST_18jun02" may be used. Implementing Zoning on an Existing Fabric The fact that zoning is already implemented eliminates the first step of getting a zone and configuration created. The next step of creating aliases and zones and then adding them to the existing configuration is the same. It is acceptable to have overlapping zones. In fact, it would be expected that the single HBA zones overlap one or more of the existing zones. Once the single HBA zones are in place, then the previous zones can be removed. After the previous zones are removed, then the aliases that are no longer needed may also be removed. Carefully executed, this will be non-disruptive to the devices on the fabric. There may be a momentary disruption of data flow when the new zoning configuration is enabled due to the RSCN. Properly configured devices will handle this without issue.
