Creating volumes
You can create a new flexible volume (FlexVol volume) by using the Create Volume dialog box. Using multiple FlexVol volumes enables you to perform administrative tasks on some of your data, while the rest remains available to users. You cannot create traditional volumes by using System Manager.
Steps 
1.
From the Home tab, double-click the appropriate storage system.
2.
Ensure that the left navigation pane displays the Vservers hierarchy.
3.
In the navigation pane, select the Vserver and click Storage > Volumes.
4.
Click Create.
5.
If you want to change the default name, specify a new name.
6.
Select the containing aggregate for the volume.
7.
Select the type of storage for which you are creating this volume.
Select Data Protection if you are creating a SnapMirror destination volume. You will have read-only access to this volume.
8.
Specify the size of the volume and the percentage of the total volume size that you want to reserve for Snapshot copies.
The default space reserved for Snapshot copies is zero percent for SAN and VMware volumes. For NAS volumes, it is five percent on storage systems running Data ONTAP 8.1.
9.
If you want to enable thin provisioning for the volume, select Thin Provisioned.
With thin provisioning, space is allocated to the volume from the aggregate only when data is written to it.
10.
If you want to enable deduplication, compression, or both on this volume, make the necessary changes in the Storage Efficiency tab.
System Manager uses the default deduplication schedule. If the specified volume size exceeds the limit required for running deduplication, the volume is created and deduplication is not enabled.
11.
Click Create.
