To add slightly to what Zlatko advised... http://www-3.ibm.com/software/sysmgmt/products/support/IBM_TSM_Supported_Devices_for_AIXHPSUNWIN.html specifies the levels and specifics you need. Note that IBM specifies in RED that the IBM device driver is needed. As always, refer to the lastest server README file for such new stuff, wherein the LTO Generation 2 Support is outlined.
