Delete snapshots

Remove snapshots of volumes from PowerFlex.

Prerequisites

Ensure that the snapshot that you are removing is not mapped to any hosts. If the snapshot is mapped, unmap it before removing it. In addition, ensure that the snapshot is not the source volume of any snapshot policy. You must remove the volume from the snapshot policy before you can remove the snapshot.

About this task

To prevent causing a data unavailability scenario, avoid deleting volumes or snapshots while the MDM cluster is being upgraded.
CAUTION:Removing a snapshot erases all the data in the corresponding snapshot.

Steps

  1. On the menu bar, click Protection > Snapshots.
  2. In the list of snapshots, select the desired snapshot, and then click More Actions > Delete.
  3. In the Delete Volume dialog box, select an option:
    • Delete volume
    • Delete volume with all its snapshots
  4. Click Delete.
  5. In the next dialog box confirming the snapshots to remove, verify that you are deleting the correct snapshots, and click Delete.
  6. Verify that the operation has finished and was successful, and click Dismiss.
