Force Writes to the Lowest Storage Tier for a Volume

The Import to lowest tier option forces all data written to the volume to the lowest storage tier configured for the volume. This option is typically used when importing data to a new volume from an external source.

Prerequisites

The volume must use a standard storage type. The Import to lowest tier option is not available for flash-optimized storage types.

About this task

When the Import To Lowest Tier check box is selected, snapshots are no longer automatically created, snapshot profiles cannot be edited, and the volume does not adhere to storage profiles. After the import is complete, clear the Import To Lowest Tier check box to avoid potential performance degradation caused by writing to the lowest tier of drives. New writes from a host to the volume will follow the Storage Profile for the volume after the Import To Lowest Tier check box is cleared.

Steps

  1. If the Dell Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
  2. Click the Storage tab.
  3. In the Storage tab navigation pane, select the volume to modify.
  4. In the right pane, click Edit Settings.
    The Edit Volume Settings dialog box appears.
  5. Click Edit Advanced Volume Settings.
    The Edit Advanced Volume Settings dialog box appears.
  6. Select the Import to lowest tier checkbox.
  7. Click OK.
