These release notes include updates to the following information in Revision D of the 
BlueScale Encryption User Guide:

• “Assigning a Key to a Partition” in all chapters on using BlueScale Standard and 

Professional Editions, covered below

• Chapter 11. Endura Decryption Utility, covered on page 5

The following information applies to “Assigning a Key to a Partition” in the chapters on 
using the Standard and Professional Editions of BlueScale Encryption for the T50, 
T120, and T950 libraries (Chapters 4, 5, 8, 9).

Before changing a partition’s encryption options, make sure all drives in the partition 
are unloaded–that is, do not have tapes in them.The changes to the encryption options, 
including adding encryption, do not take effect until after the tape drives are unloaded. 
If a tape is loaded while encryption options are changed, the changes don’t take effect 
until after the drive unloads the tape and loads a new one.

For example, if you replace the encryption key for a partition with a loaded tape, the 
tape is still encrypted with the old key; the new key is used for encrypting data for the 
next tape.

When the M-of-N feature is used while exporting an encryption key, the key is split 
into several portions that are saved in multiple files with the same file name. For 
encrypted data that has an encryption key consisting of multiple key files, add an extra 
step in the EDU decryption process: make sure that each key has a unique name prior 
to running the EDU command.
