Hi,

I have configured Bacula for our Qualstar TLS-8466 autochanger and everything 
seems be working fine except for the weird errors in slot numbering. The 
problem I suspect is with the extra I/O slot which this model has, in addition 
to normal slots in the mounted magazines. Mtx command correctly reports all 
magazine slots plus the I/O slot (separately). However, Bacula director seems 
to have issues with the I/O slot: when command is issued to mount slot 1, it 
does mount the tape from first slot of the first magazine but somehow records 
mounted slot number as (last magazine slot + 1), e.g. slot 45 when there are 4 
x 11-slot magazines (total regular 44 slots) installed in the changer. Weirdly 
enough, everything seems to work fine whether the this slot is referred to as 
slot=1 or slot=45 in mount/umount commands. It looks like I/O slot address 
overlaps with the first slot address. Not sure if this is a feature or a bug? 
Should I leave first slot of the first magazine empty to avoid the confusion or 
is there some other known workaround?

Thanks,
Ivan
