 Hi everyone, I know a few of you offered suggestions to me about a 
problem I was having with getting FreeBSD to work with an auto changer 
and I kept getting Logical unit not supported errors, so today we were 
able to use a gentoo linux live cd with a copy of mtx and we were able 
to use mtx mt and tar to move the tape write data to the tape and list 
the data on the tape, yet whenever I try to use these same tools under 
FreeBSD and I try to do media moment or read/write operations it allways 
errors with a "Logical unit not supported" error yet the Fiber channel 
HBA is being detected with the isp driver and camcontrol reports th IBM 
ultrium drive as pass0 sa0 at target 0 lun0 and the changer itself is 
detected as pass1 ch0 at target0 lun1 some interesting thins we have 
found that under FreeBSD either the the changer is not recieving the 
commands from the HBA or it does not recognize the commands for example 
this was reported after manually loading a tape and trying to tar to it..

anyway I'm told someone here may have an Idea on how to get this 
straightened out, I would be more than happy to provide additional 
debugging output, any assistance would be tremendously appreciated as I 
have been hitting a brick wall for about 3 months on this problem.. 
again thanks in advance ..
