Dennis,

We have run into this situation as well.  I pulled this out of our Gresham
Solutions Directory:

As you know an IBM LTO drive uses the atape driver on the AIX platform with
TSM.
However an HP LTO drive is not supported by the atape driver. atape is only
for the IBM drive. Therefore in a TSM environment you must configure the HP
LTO drive with the "mt" driver, create mt devices in TSM, and use device
class LTO with ultrium2c compression.

I hope this helps.
