Need some help with a new changer

[lauro1]

I'm new to amanda and really can use some help installing a new 
changer. The new unit is a Overland Minilibrary (15-slot) with 1 
DLT-7000 drive. Our old unit is working fine but our filesystems have 
grown a lot. The new unit is a model 7115.

The problem appears to be my mtx configuration. Any help is greatly 
appreciated!!!
