You can view current fractional space reservation settings to ensure that the policy in force for each LUN is configured appropriately.
Only the Drive Letter or Mount Point column displays LUN-specific information. All other columns in the Current Settings tab display information that applies across the volume that contains the LUN.
The SnapManager fractional space reservation policy includes a separate, Exchange-aware automatic deletion feature. The SnapManager automatic deletion feature can be used in place of or along with the Data ONTAP automatic deletion feature; you can also select to disable the SnapManager automatic deletion feature.
