That command would be fine if DKA400: were a disk (or rather,
if it were MKA400:) but for a disk saveset you need to specify
the directory don't you:

 $ backup/image dka400:[000000]vms072.b/save dka0: /VERIFY

I'm not sure that [000000] is right; I am sure, however,
that omission of /VERIFY was just a careless oversight
when copying the command :-)

If you can now boot, try booting OpenVMS off
the CD. This started to work with (IIRC) OpenVMS
VAX V6.1 and is now quite possibly supported:

B/R5:10000000 DKA400:

(that's 1 followed by 7 zeroes).

Apart from anything else, this will exercise
your system considerably more than just booting
SABACKUP.

It's possible that the drivers just don't like
your CDROM (although they seem to like it
more than your previous one).

If this still does not work, do you have access
to a genuine RRD4x or even a SONY CDU-??? (many
of the RRD4x drives were SONY CDUs of one sort
or another - after a while DEC stopped *paying extra*
to have the headphone socket torn out!!)
