About the EKM License

Quantum Scalar i40 and Scalar i80 User's Guide
was previously written to the media in a non-encrypted format. In
order for data to be encrypted, the media must be blank or have
been written to using Library Managed Encryption at the first write
operation at the beginning of tape (BOT).
• You cannot append encrypted data to a non-encrypted tape.
• You cannot append non-encrypted data to an encrypted tape.
• Only one data encryption key can be used per tape cartridge.
• Encryption is configured by partition. Partitions must be configured
for "Library Managed Encryption" or LME. EKM partitions must
contain only the tape drives supported by the encryption system
you are using. (For more information, see
Partitions for Library Managed Encryption
• In order to perform current or selective encryption key export
operations in Scalar Key Management (SKM) server environments,
tape cartridge barcode label information is used to associate and
locate encryption keys for respective media. If the barcode label on
encrypted media is changed, the SKM servers may not be able to
locate the respective encryption key unless the SKM server database
is updated with the new barcode label information. If the barcode
on any encrypted media is changed and data has not been rewritten
with a new encryption key associated with the new barcode label,
contact Service to correct barcode label associations in the SKM
server data bases before performing a current or selective
encryption key export operation.
If you purchase an EKM license after you purchased your library, you
must install the license key on your library to enable the EKM
functionality. See Adding or Upgrading Licensable Features
for instructions.
The EKM license applies to the entire library, regardless of how many
slots are licensed. If you increase the number of slots in your library,
your existing license applies to your new library configuration.
