TABLE 72 Zone merging scenarios: Mixed Fabric OS versions
Description Switch A Switch B Expected results
Switch A is running Fabric OS 7.0.0
or later.

NOTE
When merging mixed versions of Fabric OS where both sides have default zone mode No Access set, the merge results vary

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. Use the cfgtransshow --opentrans
command to display a list of domains with open transactions
If no other transaction is open in this fabric, no message is shown.
of what is shown if there is not a pending zoning transaction in the fabric

Similar messages are shown for cfgSave and cfgEnable:

You are about to enable a new zoning configuration.
This action will replace the old zoning configuration with the
