To access the rest of the discs in the magazine - which are implemented as LUNs by
the Pioneer changer, try this:

$ MCR SYSGEN CONNECT $44$DKB201:/NOADAPTER
$ MCR SYSGEN CONNECT $44$DKB202:/NOADAPTER

... for the rest of the discs

You should then ba able to access all of the discs individually. Note that you will log
some device errors if you have several discs mounted and access them causing
a switch of the loaded disc, and you don't want multiple processes to go after 2 or more
discs at the same time (changer starts thrashing, not much useful data transfer occurs).
