Posted on by
  1. Identify the volumes to be part of the consistency group snapshot.
  2. You can create a new snapshot policy or an existing.
  3. Assign the policy to the volumes in question.
  4. Go to Schedules and create a new schedule or modify the existing to start at the desired time
  5. Once the snapshots have been created you can create the flexclone volumes.
