Beginning with ONTAP 9.8, if you are a cluster administrator at the advanced privilege level, you can proactively promote data to the performance tier from the cloud tier using a combination of the tiering-policy and the cloud-retrieval-policy setting.

About this task

You might do this if you want to stop using FabricPool on a volume, or if you have a snapshot-only tiering policy and you want to bring restored Snapshot copy data back to the performance tier.

Promote all data from a FabricPool volume to the performance tier

You can proactively retrieve all data on a FabricPool volume in the cloud tier and promote it to the performance tier.

Steps

  1. Use the volume modify command to set tiering-policy to none and cloud-retrieval-policy to promote.

    volume modify -vserver <vserver-name> -volume <volume-name> -tiering-policy none -cloud-retrieval-policy promote

Promote file system data to the performance tier

You can proactively retrieve active file system data from a restored Snapshot copy in the cloud tier and promote it to the performance tier.

Steps

  1. Use the volume modify command to set tiering-policy to snapshot-only and cloud-retrieval-policy to promote.

    volume modify -vserver <vserver-name> -volume <volume-name> -tiering-policy snapshot-only cloud-retrieval-policy promote

Check the status of a performance tier promotion

You can check the status of performance tier promotion to determine when the operation is complete.

Steps

  1. Use the volume object-store command with the tiering option to check the status of the performance tier promotion.

    volume object-store tiering show [ -instance | -fields <fieldname>, ... ] [ -vserver <vserver name> ] *Vserver
[[-volume] <volume name>] *Volume [ -node <nodename> ] *Node Name [ -vol-dsid <integer> ] *Volume DSID
[ -aggregate <aggregate name> ] *Aggregate Name
    volume object-store tiering show v1 -instance

                                  Vserver: vs1
                                   Volume: v1
                                Node Name: node1
                              Volume DSID: 1023
                           Aggregate Name: a1
                                    State: ready
                      Previous Run Status: completed
                 Aborted Exception Status: -
               Time Scanner Last Finished: Mon Jan 13 20:27:30 2020
                 Scanner Percent Complete: -
                      Scanner Current VBN: -
                         Scanner Max VBNs: -
      Time Waiting Scan will be scheduled: -
                           Tiering Policy: snapshot-only
     Estimated Space Needed for Promotion: -
                        Time Scan Started: -
  Estimated Time Remaining for scan to complete: -
                    Cloud Retrieve Policy: promote

Trigger scheduled migration and tiering

Beginning with ONTAP 9.8, you can trigger a tiering scan request at any time when you prefer not to wait for the default tiering scan.

Steps

  1. Use the volume object-store command with the trigger option to request migration and tiering.

    volume object-store tiering trigger [ -vserver <vserver name> ] *VServer Name [-volume] <volume name> *Volume Name
