Enabling cloud write mode - FSx for ONTAP

Enabling cloud write mode

Use the volume modify ONTAP CLI command to enable or disable cloud write mode for an existing volume. For more information, see volume modify in the NetApp ONTAP Documentation Center.

Prerequisites for setting cloud write mode are:

  • The volume must be an existing volume. You can only enable the feature on an existing volume.

  • The volume must be a read-write (RW) volume.

  • The volume must have the All tiering policy. For more information about modifying a volume's tiering policy, see Updating a tiering policy.

Cloud write mode is helpful for cases like migrations, for example, where large amounts of data are transferred to a file system using the NFS protocol.

To set a volume's cloud write mode (ONTAP CLI)

  1. To access the ONTAP CLI, establish an SSH session on the management port of the Amazon FSx for NetApp ONTAP file system or SVM by running the following command. Replace management_endpoint_ip with the IP address of the file system's management port.

    [~]$ ssh fsxadmin@management_endpoint_ip

    For more information, see Managing file systems with the ONTAP CLI.

  2. Enter the ONTAP CLI advanced mode using the following command.

    FSx::> set -privilege advanced
Warning: These advanced commands are potentially dangerous; use them only when
     directed to do so by NetApp personnel.

  3. Use the following command to set the volume’s cloud write mode, replacing the following values:

    • Replace svm_name with the name of the SVM that the volume is created on.

    • Replace vol_name with name of the volume for which you are setting cloud write mode.

    • Replace vol_cw_mode with either true to enable cloud write mode on the volume or false to disable it.

    FSx::> volume modify -vserver svm_name -volume vol_name -is-cloud-write-enabled vol_cw_mode

    The system responds as follows for a successful request.

    Volume modify successful on volume vol_name of Vserver svm_name.
