Hello Pundits

Hello

An auditor has visited us lately and suggested we encrypt backup tapes sent
to external facility.
Tape is a 3580 LTO7, machine is P9 7.3 .
I've found here
https://www-01.ibm.com/support/docview.wss?uid=nas8N1021280
http://www-01.ibm.com/support/docview.wss?uid=nas8N1017856

that the 3580 tape is capable of hardware encryption/decryption if you
configure it with something known as SKLM .
I've noticed that the A/M SKLM is a Windowz/Linux tool not an IBMi one.
Now, How a Windowz/Linux tool causes a 3580 tape connected to IBMi to
encrypt/decrypt ?

SKLM is only here to store the encryption keys used to encrypt the media.
All the encryption is done by the tape drive, on the fly once it agrees with SKLM about those keys, when the IBM i requests (with BRMS, I do not remember where you specify it, maybe in the media policy or in the control group) that the backup must be done on an encrypted tape.

Notice that SKLM can also be used in the same way to store encryption keys used to encrypt disk drives in external storage devices such as DS8k or Storwize.

Any help will be greatly appreciated
