RZ25-E in a VAXstation 4000 vlc?

Hi,

I bought a Fujitsu 9.1GB drive which doesn't work with OpenVMS 7.3 on a
VAXstation 4000/90 - I think it is because the firmware is not able to
determine the capacity correctly. I will soon be installing OpenBSD on
it and don't expect problems with that OS. I have had success with an
RZ28L which is 2.1GB, not had a chance to try the 4.3GB variety of RZ
drive.

If you want to get a replacement drive that will fit in the case, look
out for an -L variant - these are the 'low profile' version of drives.

Happy vaxing

Mark.

Yes it does. I think mine came with an RZ23L in it. I swapped
in a Fujitsu 1GB SCSI drive that I had lying around.

IIRC there's a SCSI connector on the rear so you should be
able to hook up an external enclosure and check that the console
sees the new drive(s).

I'd be surprised if *any* DEC RZ drive failed to work.
I'd expect the success with non-DEC drives to be entirely
OS-dependant (assuming you sort out the usual issues with
active termination and so on). OpenVMS V6.1 (or so) onwards
is pretty tolerant of SCSi drives ... I don't know about
the BSD family and Linux-VAX is not (yet) ready to
play with disks (AFAIK).
