DSSI drives are intelligent and can be accessed from VAX firmware utility.
I have done this with KFQSA, KA650, and RF71. Drive has internal operating
system with a command prompt, diagnostics, etc.
The RF drive built in utilities and diagnostics are described here:
RF Series Integrated Storage Element User Guide
Order Number: EK-RF72D-UG-008

Note however if the fault LED is on you might not be able to access
the drive at all to run the utilities and diagnostics:
Theory of Operation 2-33
If the controller portion of the ISE is not
functioning, the fault LED on the drive module and the
fault LED on the operator control panel turn on (Figure
2-19). Also, the ISE is not visible on the DSSI bus.
The failing component, in this case, is the drive
module itself, because it houses the controller
electronics.
