Basic Setup Procedure:
  1. Register the license key.
  2. Log in with the security administrator account.
  3. Enable the key management function.
  4. Set the master key.
  5. Export and import the encryption key.
  6. Export the master key.
Operational Examples:
  • Data Sharing between Centers: Setting the same master key for multiple tape libraries enables them to share data cartridges.
  • External Storage of Data Cartridges: Encrypted data cartridges can be stored at an external location for disaster recovery and can be read even if lost or stolen.
  • Encryption of Each Logical Library (or Partition): In a logical library/partition configuration, the master key can be assigned individually.
  • Interoperation among LT-series Models: Compatible master keys and encryption keys allow sharing of data and cartridges among LT-series tape libraries.
