[OT] stenc and library...

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.
