Paul, 

I went to my QBUS based PDP-11/23 system which uses the RLV11 controller
and disconnected the last drive in the chain.  When power was applied,
that drive's Fault and unit number lights lit up.  After the normal delay,
the load light lit (Tongue twister :-) on all drives.  When reconnected into
the chain, the fault and unit number lights went out.

The RL02 and RA80 drives typically used on the VAX-11/730 were 
connected to the RB730 Integrated Disk Controller (IDC).  I suggest you
check that the daisy chain cable is plugged in all the way to the board.

Check also that the head lock plate has been swung out of the way.
If you can't open up the drive door under power, undo the two Philips 
head screws on the right hand side of the drive and pull the exposed pin down.
Loosen the screw that holds the plate in and let it drop down then tighten
the screw again.
