It sounds to me that you have this device strapped to be in 'stacker' mode- the command you're sending is the same as an 'mt offline' command- so it's loading the next tape in the changer. that means it won't show up as a changer on lun 1. I haven't seen one these beasts for 5-6 years- I don't recall what the switch settings are, but IIRC HP switch settings made no sense.
