Select the checkbox if you want to create a SnapLock volume.
Although the term “SnapLock volume” is often used to describe volumes that contain Write-Once-Read-Many (WORM) data, in fact SnapLock is an attribute of the volume’s containing aggregate. Any volume, flexible or traditional, contained by a SnapLock aggregate is by definition a SnapLock Volume.
To create a FlexVol that uses SnapLock, you must already have a SnapLock aggregate of the appropriate type (SnapLock Compliance or SnapLock Enterprise) with sufficient space to contain the new FlexVol. If such a SnapLock aggregate is not available, you will not be able to create the new SnapLock volume.
If you want to create a traditional volume that uses SnapLock, the traditional volume is so tightly bound to its aggregate that you can create the traditional volume and its aggregate in one operation. You do not need to have a SnapLock aggregate available.
