• Enable Write Early Ack: When selected, enables tape write pipelining on this tape LUN. Use
this option to speed long serial writes to tape, especially for remote backup operations.
• Enable Read Ahead: When selected, enables read pre-fetching on this tape LUN. Use this
option to speed long serial read operations from tape, especially for remote restore
operations.
NOTE
The Select/Deselect All button allows you to select or deselect all available LUNs.
8. Select the desired encryption mode. Options are: Native Encryption, DF-Compatible
Encryption, and Cleartext.
• If you change a LUN policy from Native Encryption or DF-Compatible Encryption to Clear
Text, you disable encryption.
• The LUNs of the target that are not enabled for encryption must still be added to the
CryptoTarget container with the Clear Text encryption mode option.
NOTE
The rekeying interval can only be changed for disk LUNs. For tape LUNs, expiration of the
rekeying interval simply triggers the generation of a new key to be used on future tape
volumes. Tapes that are already made are not rekeyed. To rekey a tape, you need to read the
tape contents using a host application that decrypts the tape contents using the old key, then
rewrite the tape, which re-encrypts the data with the new key.
9. Set the Key Lifespan setting, then click OK.
The selected tape LUNs are added to the encryption target container.
Moving targets
The Move Targets dialog box is used to redistribute which engine encrypts which targets. It is also
useful for transferring all targets to another engine before replacing or removing engine hardware.
Moving targets to another engine may be done while traffic is flowing between the host and target.
Traffic is interrupted for a short time but resumes before the host applications are affected.
1. Select Configure > Encryption.
The Encryption Center dialog box displays.
2. Select one or more encryption engines from the Encryption Center Devices table, then select
Engine > Targets from the menu task bar. The encryption engine must be in the same group
and same fabric.
The Encryption Targets dialog box displays.
3. Select one or more targets in the Encryption Targets dialog and click Move.
The Move Targets dialog box is displayed.
4. Select an encryption engine, then click OK to close the dialog and start the move operation.
