You can create a FlexVol volume for your data by using the Create Volume dialog box in System Manager. You should always create a separate volume for your data rather than storing data in the root volume.
Before you begin
- The cluster must contain a non-root aggregate and a Storage Virtual Machine (SVM).
- If you want to create read/write (rw) volumes, you must have configured the protocols for the SVM, and you must have installed either the SnapMirror or the SnapVault license.
If you have not configured the protocols but have installed any one of these licenses, you can create only data protection (DP) volumes.
- For creating an encrypted volume, you must have installed the volume encryption license using System Manager and enabled "key-manager setup" using the command-line interface (CLI).
You must refresh your web browser after enabling "key-manager setup".
About this task
- You can enable storage Quality of Service (QoS) only for a read/write (rw) volume.
- When you create a DP volume on the sync-source SVM in a MetroCluster configuration, the volume is not replicated on the sync-destination SVM.
- When you create a DP volume in a MetroCluster configuration, the source volume is not replicated (mirrored or vaulted) in the destination SVM.
- In a MetroCluster configuration, System Manager displays only the following aggregates for creating volumes:
- In normal mode, when you create volumes on sync-source SVMs or data-serving SVMs in the primary site, only those aggregates that belong to the cluster in the primary site are displayed.
- In switched-over mode, when you create volumes on sync-destination SVMs or data-serving SVMs in the surviving site, only switched-over aggregates are displayed.
- You cannot encrypt a volume in ONTAP Cloud.
Steps
- Click the SVMs tab.
- Select the SVM and click Manage.
- Click the Volumes tab.
- Click .
- In the Create Volume dialog box, specify a new name if you want to change the default name.
- Select the containing aggregate for the volume.
- Select the Encrypted check box to enable encryption for the volume.
This option is available only if you have enabled the Volume Encryption license and if the corresponding platform is capable of supporting encryption.
- Select the type of storage for which you are creating this volume.
You have to select Data Protection if you are creating a SnapMirror destination volume. You are provided read-only access to this volume.
- Specify the tiering policy for the volume.
- 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, the default is five percent.
- Select Default, Thin provisioned or Thick provisioned for the volume.
When thin provisioning is enabled, space is allocated to the volume from the aggregate only when data is written to it.
Note: - For All Flash FAS(AFF) storage systems, the value of thin provisioning is "Default " and for other storage systems, the value of thick provisioning is "Default".
- For FabricPool, the value of thin provisioning is "Default ".
- If you want to enable deduplication 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.
For All Flash Optimized personality systems, inline compression is enabled by default.
- If you want to enable storage QoS for the FlexVol volume to manage workload performance, select the Manage Storage Quality of Service check box in the Quality of Service tab.
- Create a new storage QoS policy group or select an existing policy group to control the input/output (I/O) performance of the FlexVol volume:
| If you want to... |
Do this... |
|---|
| Create a new policy group |
- Select New Policy Group.
- Specify the policy group name.
- Specify the minimum throughput limit.
If you do not specify the minimum throughput value or when the minimum throughput value is set to 0, the system automatically displays "None" as the value and this value is case-sensitive.
- Specify the maximum throughput limit to ensure that the workload of the objects in the policy group do not exceed the specified throughput limit.
- The minimum throughput limit and the maximum throughput limit must be of the same unit type.
- If you do not specify the minimum throughput limit, then you can set the maximum throughput limit in IOPs and B/s, KB/s, MB/s, and so on.
- If you do not specify the maximum throughput value, the system automatically displays "Unlimited" as the value and this value is case-sensitive. The unit that you specify does not affect the maximum throughput.

| Select an existing policy group |
- Select Existing Policy Group, and then click Choose to select an existing policy group from the Select Policy Group dialog box.
- Specify the minimum throughput limit.
If you do not specify the minimum throughput value or when the minimum throughput value is set to 0, the system automatically displays "None" as the value and this value is case-sensitive.
- Specify the maximum throughput limit to ensure that the workload of the objects in the policy group do not exceed the specified throughput limit.
- The minimum throughput limit and the maximum throughput limit must be of the same unit type.
- If you do not specify the minimum throughput limit, then you can set the maximum throughput limit in IOPs and B/s, KB/s, MB/s, and so on.
- If you do not specify the maximum throughput value, the system automatically displays "Unlimited" as the value and this value is case-sensitive. The unit that you specify does not affect the maximum throughput.
If the policy group is assigned to more than one object, the maximum throughput that you specify is shared among the objects.

- Click Create.
- Verify that the volume you created is included in the list of volumes in the Volume window.
The volume is created with UNIX style security and UNIX 700 "read write execute" permissions for the owner.
