Is your encryption application-managed (controlled by TSM) or
library-managed (controlled by EKM/TKLM)?

If application managed, IBM is correct, you just need a different devclass
that specifies drive encryption OFF, pointing to the same library, and a new
storage pool that specifies the non-encrypted devclass.  .

I've got 4 LTO drives, onsite pool is NOT encrypted (long story there), COPY
pool IS encrypted.  No biggie.
