| Hi
Please help
I am the account manager trying to find hardware to sell with MLS+,
so please excuse me if I am inaccurate with technical details, but
I am confused by the cautiousness of the previous answers.
I have never encountered any problems with Digital Unix, where
it matters that a RZ28 is a RZ28D or Rz28M or Rz28B.
So why does MLS+ care? Do you use different drivers that are in
some way model specific?
And what about the question that the disks will be behind the HSZ's
Isnt it the HSZ firmware that drives the physical disk?
Regards
Terri

| The only reason why MLS+ cares is because we are talking about
V3.1A here (or are we?) and not V4.0A (the soon-to-be-out version).
MLS+ V3.1A is based on several obsolete versions of DIGITAL UNIX -- The
kernel (which includes the device drivers) is based on DU V3.2B and the
rest on V2 (yes that old). IF the RZ28M is happily running with
DIGITAL UNIX system V3.2B somewhere, then it should happily run with an
MLS+ V3.1A system. The problem for us comes if for some unforeseen
reason it doesn't. If the problem is something that is broken with the
base software (the non-MLS+ modifications), then it will take resources
we do not have -- and base UNIX development will not offer -- to fix.
They tell us "get the next version" -- we'd like to say that to
government customers too...
In theory, when a software product description says we support a
given piece of hardware, what that is supposed to mean is that someone
in QA or engineering actually ran the software on or with that
hardware. We in MLS+ have asssumed that because we based to DIGITAL
UNIX we support all they support (with exceptions where some security
policy disallows, e.g., ASCII printers, or where some more complex
modifications had to be made to a daemon or related data files and no
one said there was a marketing requirement to put the work in the
schedule, e.g., print servers). Since we have not tested it (no
equipment) and have neither the schedule nor the people to test it,
Mike feels uncomfortable saying it is "supported". Me? I'll commit and
then likely live (always hopeful!) to regret it :-)
No we don't use different drivers -- just secure ones :-) Meaning:
there are sometimes modifications to the drivers that have to do with
security policy, but the fundamentals of the drivers are untouched.
I don't know what you mean about the question that the disks will be
behind the HSZ's -- from the CPU's point of view that's where they are
because the HSZ firmware which drives the disk logic is in-between...
what's the question?

I dont know either, but my customer just wants to be supported,
and avoid the misery of the support center being unable to help,
but they also want to use rz28d's so they are thinking
"if they just use the d's on the Hsz's, why would Mls+
care? As the Hsz40 is supported."

P.S. I will start a new topic on this,
but the 2100 server is now a 2100A!

| 437.8 | Its M's or D's | CHEFS::HOWLETT_T | Avoiding the cracks in the pavement | Thu Feb 06 1997 07:04 | 21 |
| Hi Again,
I am trying to sell (as in Take order for) 6 Mls+ servers with lots
of disks about 80, the disk options are
From the price file
qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq
-RZ28 -VA 2.1 GB Disk w/snap-in carrier 1,007.00 M
-RZ28B-VA 2.1GB DISK W/SNAP CARRIER 1,181.00 M
-RZ28D-VA 2.1GBF 3.5"DK:IN MOD CARRIER 821.80 A
-RZ28M-VA 2.1 Gbf 3.5"DK in Mod Carrier 723.10 A
So its M's or D's ,neither is on the SPD,so we'll go for D's. I guess
this is a pain for you, and it would waste your time testing it.
Maybe I sell them, and my customer agrees if they hit a problem they
send you a spare one?
Regards
Terri

Subj: Re: Notefile DEC_MLS_PLUS Note 437.8 [RZ28 support issue]
QA has been running RZ28M-VA's off and on for several months now
with no issues that I know of.
Also, they do appear in the MLS+ V4.0a /etc/disktab that one would
use to label a disk.
