Enable or disable zero-padding policy

Use the zero-padded policy when the Storage Pool data layout is Fine Granularity (FG). The zero-padded policy ensures that every read from an area previously not written to, returns zeros.


  1. From the PowerFlex GUI, in the left pane, click Configuration > Storage Pools.
  2. In the right pane, select the relevant Storage Pool check box, and click Settings > General.
  3. In the Storage Pool <SP name> Settings dialog box, select or clear the Enable Zero Padding Policy check box.
  4. Click Apply.
  5. Verify the operation completed successfully and click Dismiss.


The zero padded policy is enabled for FG and disabled when the data layout is Medium Granularity (MG).
