Forcibly restoring encryption keys
If encryption keys cannot be used, including the keys backed up by the primary backup in the storage system, the encryption keys can be restored forcibly.
NoteTo restore the encryption key, the volumes that belong to the parity group for which the key is set must be blocked. In addition, after the key is restored, the volumes that belong to the parity group for which the key is set must be restored.
CautionIf you restore an encryption key that is not the latest key, the drive, EDKA, or controller might be blocked, and the data might not be read.
