Reverting a LUN
Reverting restores a volume or LUN to the state at which the snapshot was taken. Restoring data using snapshot revert is significantly faster than restoring individual files and folders.
- Go to Storage & Snapshots > Storage > Storage/Snapshots.
-
Select a block-based
LUN.
Important:
The LUN must have at least one snapshot.
-
Click Snapshot, and
then select Snapshot
Manager.
The Snapshot Manager window opens.
- Select a snapshot.
-
Click Revert LUN Snapshot.
Warning:
All changes made after the snapshot was taken will be deleted.
- Optional:
Configure the following settings.
Setting
Description
Take a new snapshot before reverting
QTS takes a snapshot before starting the revert. This ensures that changes made to data since the snapshot was taken are not permanently lost.
Re-map LUN to the same iSCSI target after revert
If enabled, QTS automatically remaps the LUN to its current target after reverting. If disabled, you must manually remap the LUN after reverting.
- Click Local Revert.
QTS unmaps the LUN from its iSCSI target. The status of the LUN changes to Reverting.
