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.
