Deleting a Key
To use a new key to encrypt data, you must first delete the existing key. Then you can create
the new key and assign it to one or more partitions. Note that you will need a copy of the
existing key to restore data that was encrypted with the existing key.
Only one key is allowed per LTO-4 tape. To use a tape encrypted with a deleted encryption key,
you must first scratch the tape through BlueScale Encryption. This procedure is described in
Recycling Encrypted Media
on page 98.
