Alison is probably correct. Some DEC drives do have a jumper to select
spinup on power-up, but the RZ23/24/25 definitely don't (the original
Connor drives do, but DEC changed the firmware) and some notes I have here
suggest the RZ55/56 have different firmware too.

What you'll get out of the drive depends on what the OS is trying to do: a
SCSI MODE SENSE command will work fine, but you won't be able to do
anything more interesting until the disk has spun up (which is done by
issuing a START UNIT command). DEC used to have a utility called RZSPINUP
to do this, but any SCSI utility that can issue a START UNIT command would
do as well.
