Depending on the configuration, you may or may not be able to delete or schedule the deletion of a zone and all its contents. Superusers can determine which group of users are allowed to delete or schedule the deletion of a zone and all its contents. For information about how to configure the recursive deletion of zones, see Configuring Recursive Deletions of Networks and Zones.
Note that you must have Read/Write permission to all the subzones and resource records in order to delete a zone. The possible effects of removing or re-parenting are illustrated in Figure 19.4figure Removing or Reparenting Subzones.
The appliance puts all deleted objects in the Recycle Bin, if enabled. You can restore the objects if necessary. When you restore a parent object from the Recycle Bin, all its contents, if any, are re-parented to the restored parent object. For information about the Recycle Bin, see Using the Recycle Bin.

zone having10.10.in-addr.arpa + 10.0.0.1
(PTR record) - If you add
10.in-addr.arpa
, then10.10.in-addr.arpa
is reparented under10.in-addr.arpa
- and
10.0.0.1
PTR record is reparented fromin-addr.arpa
to10.in-addr.arpa.
- If you delete
10.in-addr.arpa
, then10.10.in-addr.arpa
is reparented under in-addr.arpa (depending on the Remove zone only/ Remove all subzones option) and 10.0.0.1 PTR record is deleted along with 10.in-addr.arpa zone. - When you remove a zone and reparent its subzones, any subzone that inherited its admin access settings from its previous parent zone (as opposed to having specific access settings for the subzone) now receive their settings from its new parent zone, which might be different. See Figure 19.5.

To remove a zone:
- From the Data Management tab, select the DNS tab -> Zones tab.
- Click the checkbox of the zones you want to delete.
- Click the Delete icon.
- Select one of the following. Note that these options appear only if you are allowed to delete zones and all its contents. For information about how to configure this, see see Configuring Recursive Deletions of Networks and Zones.
- Remove zone only: Select this to remove the zone and all its content. The appliance reparents all subzones to the parent zone of the zone that you want to remove, except for the automatically created AD (Active Directory) subzones.
- Remove all subzones: Select this to remove the selected zone, all its subzones, and all the resource records of the selected zone and its subzones.
- Click Yes. Grid Manager displays a warning message. Click Yes to continue or No to cancel the process. Note that this process may take a longer time to complete depending on the size of the data.
You can also schedule the deletion for a later time. Click Schedule Deletion and in the Schedule Change panel, enter a date, time, and time zone. For information, see Scheduling Deletions. For information about scheduling recursive deletions of zones, see see Scheduling Recursive Deletions of Network Containers and Zones.
