• The volume is moved to the recovery bin. • Pages are overwritten with zeros as a background operation. • Page map entries are cleared. Known Limitations • This process consumes system resources. I/O timings are also slightly impacted while the data is being cleared. • The deleted pages are not immediately available for new allocation in existing or new volumes. • Under certain conditions, such as FST (free space trouble), when old snapshots are deleted automatically, or if some pages are moved out of the system, clearing the data might delay recovery from the FST process. By default, secure erase is disabled on the group. To enable Secure Erase: 1. Click Group → Group Configuration. 2. Click the Advanced tab. 3. In the Secure Erase panel, check the Enable secure erase data checkbox. To disable the feature, deselect the Enable secure erase data checkbox. About Group-Level Security 109
