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.
In the navigation pane, click Storage > Volumes.
3.
Click Create.
4.
If you want to change the default name, specify a new name.
5.
Select the containing aggregate for the volume.
If the containing aggregate is enabled for SnapLock compliance, the FlexVol volume created has mandatory SnapLock protection.
6.
Click the type of storage (NAS or SAN) for which you are creating this volume.
7.
Specify the size of the volume and the percentage of the total volume size that you want to reserve for Snapshot copies.
8.
If you want to enable thin provisioning for the volume, do not select the "Guarantee space for volume" check box.
Selecting the "Guarantee space for volume" check box preallocates space in the aggregate for the volume. The preallocated space cannot be allocated to any other volume in that aggregate.
9.
If you want to enable deduplication on this volume, select the "Enable deduplication" check box in the Options tab.
System Manager uses the default deduplication schedule for deduplication. To change the deduplication schedule, you can use the Edit Volume dialog box.
If the specified volume size exceeds the limit of the deduplication feature, the volume is created and deduplication is not turned on.
10.
Click Create.
