After fiddling a bit with tapes, i'm trying to enable hardware encryption on
RDX, using stenc.

Seems supported:

 root@sdpve2:~# /usr/bin/stenc -f 
/dev/disk/by-id/usb-TANDBERG_RDX_008650987562-0:0 --detail
 Status for /dev/disk/by-id/usb-TANDBERG_RDX_008650987562-0:0
 --------------------------------------------------
 Device Mfg:              TANDBERG
 Product ID:              RDX             
 Product Revision:        0283
 Drive Encryption:        off
 Drive Output:            Not decrypting
                          Raw encrypted data not outputted
 Drive Input:             Not encrypting
 Key Instance Counter:    0
 Volume Encryption:       Unknown result '0'

But trying some set of 'address' index (at least, from 0 to 7) there's no
way to enroll the key:

 root@sdpve2:~# /usr/bin/stenc -f 
"/dev/disk/by-id/usb-TANDBERG_RDX_008650987562-0:0" -e mixed -a 0 -k 
"/etc/bacula/certs/sdpve2-8650987562-256-2025.key"
 Provided key length is 256 bits.
 Key checksum is 9c.

 Type 'man stenc' for more information.


I've tried also 128bit key. I've tried with mounted disk or unmounted.


Someone have some clue? Thanks.
