Encryption Methods
Choose how to encrypt data. You can use encryption-enabled QIPs or encryption-
capable LTO-4 drives to encrypt data in a partition. With encryption-enabled QIPs, data 
can be encrypted and written to tape using drives that do not directly support 
encryption (for example, LTO-2 and SAIT). With encryption-capable LTO-4 drives, the 
drive performs the encryption as it writes the data to LTO-4 tapes.
Note:
If a partition uses LTO-4 drive-based encryption, the library can load 
LTO-3 media into that partition. However, attempts to write encrypted 
data to LTO-3 media fail. Note that LTO-4 drives can successfully read 
data from LTO-3 tapes. 
The encryption performed by encryption-capable LTO-4 tape drives is not compatible 
with the encryption performed by an encryption-enabled F-QIP. You cannot use both 
types of encryption in the same partition. If an encryption-enabled F-QIP and an 
encryption-capable LTO-4 drive share a partition, you must choose one type of 
encryption or the other. You cannot use both.
To decrypt data encrypted using a QIP, use a partition configured with QIP-based 
encryption. To decrypt data encrypted using an LTO-4 drive, use a partition configured 
with drive-based encryption.
Only one encryption key is allowed per LTO-4 tape. If you lose the encryption key for 
the tape or if you want to use a different key, you must recycle the tape before you can 
re-use it in an encryption-enabled LTO-4 drive. Similarly, if the data on a tape was 
encrypted using a QIP, you must recycle the tape before you can re-use it with an 
encryption-capable LTO-4 drive. Recycling media is easily managed through BlueScale 
Encryption Key Management (see Recycling Media on page 116).
Passwords and Other Identifiers
BlueScale Encryption requires that you supply passwords and monikers (key names). 
Your site may want to consider whether specific rules govern these.
Superuser Login/Encryption Passwords   Passwords are the standard method of user 
security that restricts access. To use Spectra Logic BlueScale Encryption, you must first 
log into the library with superuser privileges, then enter an encryption password. The 
encryption password lets you access the library’s encryption features. This password 
must be entered after the superuser login. Select Security > Encryption to display the 
encryption password screen.
Password(s) for Key Import and Export   Passwords are also used to encrypt keys for 
export and when importing previously exported keys. This feature is only available 
after you log into the library as a superuser and enter the encryption password. Your 
site may want to consider whether to create different rules for these passwords, such as 
requiring that these passwords are longer than the encryption access password(s), and 
therefore more secure.
