Creating a new master key Though it is generally not necessary to create a new master key, you may be required to create one due to circumstances such as the following: • The previous master key has been compromised. • Corporate policy might require a new master key every year for security purposes. When you create a new master key, the former active master key automatically becomes the alternate master key. The new master key cannot be used (no new data encryption keys can be created, so no new encrypted LUNs can be configured), until you back up the new master key. After you have backed up the new master key, it is strongly recommended that all encrypted disk LUNs be re-keyed. Re-keying causes a new data encryption key to be created and encrypted using the new active master key, thereby removing any dependency on the old master key. 1. Select Configure > Encryption. 2.
