LTO-4 drives require that all data encrypted and written to a single tape use the same 
encryption key—that is, a single key is associated with all the encrypted data on an 
individual tape. After encrypted data is written to a tape, the drive will not overwrite 
the data using a different encryption key until you recycle the tape through BlueScale 
Encryption. If you lose the encryption key for a tape, you must recycle the tape before 
you can re-use it.

Note:

Keep the following in mind when you recycle media.

ƒ If you plan to use the same key that was used to encrypt the data already on the 

tape, you do not need to recycle the tape using the process described in this 
section.

ƒ Make sure that the backup software cannot access the drive you plan to use for 

recycling the media during the recycling operation.

ƒ The recycle media operation can only be performed using the touch screen (or 

using a keyboard and mouse connected to the LCM). You cannot access the 
Import/Export TeraPack Cases screen when using a remote connection to the 
library.

Follow these steps to recycle one or more encrypted LTO cartridges so that they can be 
reused with a new encryption key.

1. From the toolbar menu, select General > Import/Export. The Import/Export 

TeraPacks screen displays (Figure 54).

2. Select the partition containing the tapes that you want to recycle from the Partition 

drop-down list, then select Go.
