A SED RAID Set is a RAID Set that has been locked on a controller that holds a security key. When you delete existing SED RAID sets, there has one option available to perform an Instant Secure Erase. The “Secure Erase The Member Disks” function is the process of permanently erasing all data on the SED disks and resetting the security attributes. The data on the SED disk is lost. The data encryption key remains in the disk if you delete a SED raidset without secure erase. SED feature has two keys: access control key and data encryption key. Password is the access control key. Change password only revises the access control key not the data encryption key.
