I have a 3584 library and planning on ading LTO4.  I know LTO4
drives support encryption by the drive.

1.  As LTO4 drives can read and write LTO3 tapes also,
can it do encryption on LTO3 tapes?

2.  With encryption on LTO tapes.  When an encrypted tape
is "reclaimed" by TSM, is it just another scratch tape?  I mean
can it then be written as encrypted or unencrypted, or is there
some extra step to use a scratch tape that was encrypted as
unencrypted?  (Perhaps a silly question, but maybe not.)

Thanks,
David Longo
