Connectivity With Backup Software; Purchasing A License; Changing The System Firmware - Fujitsu ETERNUS LT260 User Manual

Chapter 4 Considerations

4.4 Connectivity with Backup Software

4.4 Connectivity with Backup Software
On a system using the key management function, Fujitsu recommends using verified backup software.
If unverified backup software is used, encryption may not work normally. For more information, contact your
sales representative.
If your backup software supports the encryption function of Ultrium5 or later tape drives, be sure to disable
the encryption function of the backup software as necessary.
4.5

Purchasing a License

To issue a license for using the Key Management Function Option, the serial number of the tape library is
required. If the LT260 has already been purchased, provide the serial number of the tape library to your sales
representative to obtain this license.
If the Key Management Function Option is purchased with the tape library, no action is necessary because the
license has already been set.
4.6

Changing the System Firmware

The following operations are required to downgrade the system firmware from version 6.70 or later (for the
LT260 in which the Key Management Function Option is being used) to version 6.56 or earlier (for which the
Key Management Function Option is not supported).
• Deleting the master key
• Deleting the encryption key
• Disabling the key management function
Since the encrypted data cannot be read after the master key and the encryption key are deleted, be sure to
export the master key and the encryption key in advance and keep them in a safe place.
