3-4 Full Disk Encryption
3.4.1.2 Create the Security Key
You need to enter the security key to perform certain
operations. You can choose a strong security key that the
controller suggests.
Caution: If you forget the security key, you will lose access to
your data.
3.4.1.3 Create a Passphrase (Optional)
The pass phrase provides additional security. The pass phrase
should be different from the security key. If you choose this
option, you must enter it whenever you boot your server.
Caution: If you forget the pass phrase, you will lose access to
your data.
When you use the specified security key identifier, security key, and pass
phrase, security will be enabled on the controller.
3.4.2 Change Security
You can change the security settings on the controller, and you have the
option to change the security key identifier, security key, and pass
phrase. If you have previously removed any secured drives, you still need
to supply the old security key to import them.
There are three procedures you can perform to change the security
settings on the controller:
•
Change the security key identifier
•
Change the security key
•
Change a pass phrase
See Section 4.5, “Selecting Full Disk Encryption Security Options” for the
procedures used to change security options in WebBIOS or Section 8.2,
“Selecting Full Disk Encryption Security Options” for the procedures used
to change security options in MegaRAID Storage Manager.
