Dell EMC PowerVault MD 34XX/38XX Series Storage Arrays Administrator's Guide

In the AMW, when you select a security enabled physical disk that is not part of a disk group, the Secure Erase menu item is enabled on the Physical Disk menu. You can use the secure erase procedure to re-provision a physical disk. You can use the Secure Erase option if you want to remove all of the data on the physical disk and reset the physical disk security attributes.

Before you complete this option, make sure that the physical disk that you have selected is the correct physical disk. You cannot recover any of the data that is currently on the physical disk.

After you complete the secure erase procedure, the physical disk is available for use in another disk group or in another storage array. See help topics for more information about the secure erase procedure.
