To restore a LOCAL key that was deleted, create a new LOCAL key with the same keyname and value as the deleted key. You must have first recorded, or backed up, this information before the key was deleted. The backup procedure is described in Backing Up a LOCAL Key (BUI). Although deleting a LOCAL key renders shares inaccessible, the shares can be made accessible again by recreating the LOCAL key.
For information about restoring keys stored in the OKM keystore, refer to the Oracle Key Manager documentation on the Oracle Technology Network (https://docs.oracle.com/en/storage/).
Use the following procedure to restore a backed up LOCAL key.
If the keyname is used with existing shares, a dialog box appears. To overwrite the key value in the existing shares, click OK. Click Cancel to not add the new key. You can then change the key used for those shares before repeating this procedure and restoring the original key. For more information, see Changing a Share Encryption Key (BUI).
