A bit OT but i don't know where to ask...
I'm using stenc to load keys to LTO tapes; if the LTO tape is 'single',
internal or external does not matter, i can inqiry ectryption status easily:
root@svpve3:~# stenc -f /dev/st0 --detail
Status for /dev/nst0
--------------------------------------------------
Device Mfg: IBM
Product ID: ULTRIUM-HH9
Product Revision: Q3F5
Drive Encryption: mixed
Drive Output: Decrypting
Unencrypted data outputted
Drive Input: Encrypting
Key Instance Counter: 1
Encryption Algorithm: 2
Drive Key Desc.(uKAD): "svpve3-10WT017440-2025"
Volume Encryption: Encrypted and able to decrypt
Volume Algorithm: 3
if i try to do the same thing on a (tape in a) tape library, i got:
root@cnpve3:~# stenc -f /dev/st0 --detail
Status for /dev/nst0
--------------------------------------------------
Could not open device '/dev/nst0': ERROR: Device Busy
I think the culprit came from the fact that on a simple tape storage
configuration i have:
Always Open = no
while on the library storage conf i have:
Always Open = yes
There's something i can do? Reading docs seems to me that 'Always Open =
yes' is preferrable and needed for tape library (so my choice); i cannot do
an 'umount' every time i need to check for key; probably better a 'release'?
Thanks.
