Concurrent zone transactions
11
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 work space 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 will warn 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.
Example of what is shown if there is not a pending zoning transaction in the fabric
sw0:FID128:admin> zonecreate z7, "4,5;10,3"
sw0:FID128:admin>
Similarly for cfgSave and cfgEnable:
u30:FID128:admin> cfgenable cfg
You are about to enable a new zoning configuration.
This action will replace the old zoning configuration with the
current configuration selected. If the update includes changes
to one or more traffic isolation zones, the update may result in
localized disruption to traffic on ports associated with
the traffic isolation zone changes
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
