Create internal security key
To use the Drive Security feature, you can create an internal security key that is shared by the controllers and secure-capable drives in the storage array. Internal keys are maintained on the controller's persistent memory.
Create external security key
To use the Drive Security feature with a key management server, you must create an external key that is shared by the key management server and the secure-capable drives in the storage array.
Change security key
At any time, you can replace a security key with a new key. You might need to change a security key in cases where you have a potential security breach at your company and want to make sure unauthorized personnel cannot access the drives' data.
Switch from external to internal key management
You can change the management method for Drive Security from an external key server to the internal method used by the storage array. The security key previously defined for external key management is then used for internal key management.
Edit key management server settings
If you configured external key management, you can view and edit the key management server settings at any time.
Back up security key
After creating or changing a security key, you can create a backup copy of the key file in case the original gets corrupted.
Validate security key
You can validate the security key to make sure it has not been corrupted and to verify that you have a correct pass phrase.
Unlock drives when using internal key management
If you configured internal key management and then later move secure-enabled drives from one storage array to another, you must re-assign the security key to the new storage array to gain access to the encrypted data on the drives.
