96 Zone administration
Refreshing the Zone Admin module information
The information displayed in the Zone Admin module is initially a snapshot of the contents of the fabric
zoning database at the time the module is launched. Any changes you make to this view are saved to a
local buffer; they are not applied to the fabric zoning database until you invoke one of the transactional
operations listed in the Actions menu.
Any local zoning changes are buffered by the Zone Admin module until explicitly saved to the fabric. If the
fabric zoning database is independently changed by another user or from another interface (for example,
the CLI) while Advanced Web Tools zoning changes are still pending, the refresh icon starts to blink
(after a 15 second polling delay). You can then choose to refresh the current Advanced Web Tools zoning
view to reflect the new, externally changed contents of the fabric zoning database. Any pending local
changes are then lost. You can also ignore the blinking refresh icon and save your local changes,
overwriting the external changes that triggered the icon to blink.
Another reason to refresh zoning is to back out of current, unsaved work and start over.
You can refresh the zoning information at any time, either using the refresh icon (whether it is flashing or
not) or from the View menu.
The following procedure updates the information in the Zone Admin module with the information saved in
the zoning database on the switch.
CAUTION: When you refresh the buffered information in the Zone Admin module, any zoning
configuration changes you have made and not yet saved are erased from the buffer and replaced with the
currently enabled zone configuration information that is saved on the switch.
To refresh the local Zone Admin buffer from the fabric zoning database:
1. Launch the Zone Admin module as described on page 95 .
2. Select View > Refresh Zoning or click the zone refresh icon , located in the lower right corner of the
Zone Admin module.
This refreshes the information in the Zone Admin module with the information in the switch’s zoning
database. This action also refreshes the fabric information as described in this section. Any unsaved
zoning changes are deleted.
Saving local zoning changes
All information displayed and all changes made in the Zone Admin module are buffered until you save the
changes. That means that any other user looking at the zone information for the switch does not see the
changes you made until you save them. Saving the changes propagates any changes you have made in
the Zone Admin module (buffered changes) to the zoning database on the switch. If another user has a
zoning operation in progress at the time that you attempt to save changes, a warning is displayed
indicating that another zoning transaction is in progress on the fabric. You can select to abort the other
transaction and override it with yours.
This action updates the entire contents of the Zone Admin module, not just the selected zone, alias, or
configuration. You can save your changes at any time during the zone administration session.
To save Zone Admin module changes to the switch zoning database:
1. Make your zoning changes in the Zone Admin module.
2. Select Actions > Save Config Only.
