M5977 PDP11 SCSI card dip's

Hi, I'm just starting to get into a PDP11/83 machine I have here and I want to add some more storage but I'm having some issues. For starters this is what I got M5977-AA SCSI board (Is this the same as RQZX1?) two RZ24L 240MB HD from Quantum combo tape and 5.25 RX33 Drive All components work. But I can only get one HD to be recognized (one is ID 0 the other is set to 1). though it's accessed as just DU0. I also know that max devices I can have on the M5977 is 16. With SHOW DEVICES I see DU1, DU2 as offline and type:unknown Now for my stupid questions: Is each partition treated as 1 device (meaning can I have 2x240MB AND the tape/RX33 drives)? If so, how do I add the 2nd HD and get it recognized (LOAD? SET?)? I don't have a manual for any of this equipment, and I don't really know RSX yet.
