Beginning with ONTAP 9.12.1 P2, you can create a new volume or modify an existing volume to enable support for a maximum volume size of 300TB and a maximum file (LUN) size of 128TB.

Before you begin

  • ONTAP 9.12.1 P2 or later is installed on the cluster.

  • If you are enabling large volume support on the source cluster in a SnapMirror relationship, you must have ONTAP 9.12.1 P2 or later installed on the cluster hosting the source volume as well as the cluster hosting the destination volume.

  • You are a cluster or SVM administrator.

Create a new volume

Step

  1. Create a volume with large volume and file support enabled:

    volume create -vserver <svm_name> -volume <volume_name> -aggregate <aggregate_name> -is-large-size-enabled true
Example

The following example creates a new volume with large volume and file size support enabled.

volume create -vserver vs1 -volume big_vol1 -aggregate aggr1 -is-large-size-enabled true

Modify an existing volume

Step

  1. Modify a volume to enable large volume and file support:

    volume modify -vserver <svm_name> -volume <volume_name> -is-large-size-enabled true
    Example

    The following example modifies an existing volume to support large volume and file size.

    volume modify -vserver vs2 -volume data_vol -is-large-size-enabled true

  2. Activate the new configuration settings by remounting the volume:

    volume unmount -vserver <svm_name> -volume <volume_name>
    volume mount -vserver <svm_name> -volume <volume_name>
