Gilles,
Earliest of DATs (gen 1) did have internal eject dip switches but this all was replaced by the ability to set these in software. I don't recall these in any later autoloader devices. Then again, IIRC these things always "just worked" for me, so I never had to dig very deeply.

Autoloader modes
HP StorageWorks DAT autoloaders may be operated in either stacker or random mode.
Mode is initially determined by what happens after you insert a magazine:
* If the host sends a command to move a cartridge from the magazine to the drive, the
autoloader goes into random mode
* If you select a cartridge by pressing the Select button and then load it by pressing the Load
Cartridge button, the autoloader goes into stacker mode
See the electronic User's Guide on the HP StorageWorks Tape CD-ROM for more information
about autoloader modes
There is nothing in standard MPE that "sends a command to move a cartridge." So you should ALWAYS be in "stacker mode." I would re-recommend the "eject" setting on Devctrl. If that isn't working then maybe something is actually broken.
Good luck,
Jim

I've tried that, but unable to coax the drive to go online.
The only way I can put the drive online is by pressing various
buttons on the front panel of the unit.
Kinda makes the "autoloader" part of this unit pretty useless.
I'm thinking there must be a dip switch setting that needs to be changed.
