NOTE When merging mixed versions of Fabric OS where both sides have default zone mode No Access set, the merge results vary depending on which switch initiates the merge. Concurrent zone transactions While working on zone sets, a special workspace is provided to allow you to manipulate the zone sets of your choice. These changes are not put into effect until they are committed to the database. Once they are committed, they will replace the existing active zone sets with the new zone sets or create more zone sets in the defined database. When updates to the zoning database are being made by multiple users, Fabric OS warns you about the situation and allows you to choose which operation will prevail. Example of how users are warned if there is already a pending zoning transaction in the fabric u30:FID128:admin> zonecreate z2, "2,3" WARNING!! Multiple open transactions are pending in this fabric. Only one transaction can be saved. Please abort all unwanted transactions using the cfgtransabort command.
