After installation the same setup with with redhat linux with drivers provided in hp website, I truely believe that HP intensionally release a problematic open driver for freeBSD. Coz rehat works nicely with the changer using the drivers provided by HP (that means redhat also can't recognize this tape library using the default setup. Sad news is I will have to stick with redhat linux when everything works in order to save some money from grabbing another controller which suppose to work with freeBSD. BTW, I also have tried to install freeBSD with my Dell and a similar tape library and it works without problem. Having been told by other users that there is another controller from HP which is using LSI chipset which should works in freeBSD. But it is really a late news for me coz everything almost fixed.
