Subject: Re: VMS/VAX/Alpha questions...
not
Currently the *only* non-DEC drive in my cluster
(except those that came
in
storageworks cannisters) is in a VAXstation 4000/VLC,
and I've got major
problems with it at the moment as a bunch of the files have bad blocks
:^(
I've run a great mix of nonDEC SCSI drives on the 3100s I have and the
CMD interfaced MVII. For MFM I've tried everything I have most are
smaller
than RD53s though but they worked.
> Does DEC say: "You'll run that RZ25 &
*Be Happy About It*", or can I
run
non-DEC rommed
hard drives just fine?
RZ or not RZ, *that* is the question. ;-)
The answer, is hopelessly vague. It depends. It might work, it might work. OpenVMS and the hardware are only tested with
specific drives, as
a
result the drives may or may not work. The good news
is that OpenVMS
V7.2
is a lot less touchy about this than say VAX/VMS V5.5.
Depends what you have and what interfaces, usually it works fine.
So, you see the correct answer is, try it and find out.
Which
unfortunatly
best answer.
isn't the one you want trust me I understand as
I've looked into
upgrading
my server to a U2W SCSI controller and Ultra160 drives.
As a hobbyist
I'm
not sure I want to risk buying drives that might not
work.
Finding a U2Wscsi for a nonPCI VAX or ALPHA would be real tough.
Though Qantum fireball (scsi-II) at 5.1gb worked fine when I tried it
as a non boot disk on the M76 running VMS7.2. I tried it for laughs
as I was pulled from the server (p133!).
