Hmm. I didn't have any luck with the RZ56 and the MicroVAX 3100. I never had any time to track it down. As a first attempt to see if it will work at all, you can do a SHOW DEV at the >>> prompt to get the console to spin up all the disks. It's been my experience that NetBSD hangs while trying to probe the SCSI bus if there's an RZ56 on the SCSI bus. I'm not aware of a jumper that makes the RZ56 spin up, but there is a setting in one of the mode pages. There was a program under Ultrix called rzdisk that allowed you to, among other things, tell the drives to spin up at power on. I think there was a similar program for Alpha/VMS as well.
