3268.0. "SKY Computers Inc." by HYDRA::NEWMAN (Chuck Newman, 508/467-5499 (DTN 297), MRO1-3/F26) Tue Mar 04 1997 12:07

    Category     :  VMS
    OS Version   :  OpenVMS Alpha V6.2
    System H/W   :  AlphaServer 4/233


    Brief Description of Problem:
    -----------------------------
I remember when they came to the lab in MRO4.
The vendor writes:
--------------------------------------------------------------------------------
We at SKY Computers sell a product for numerical acceleration.  It
contains several Intel i860 chips along with a custom I/O interface. 
This product connects to various workstations via a SCSI interface.  SKY
has been selling this product for 4 years to Philips Medical Systems for
their use in a MRI machine.  They are using DEC3000 Model 400 & Model
600 running OpenVMS 6.1 and Alphaserver 4/233 running OpenVMS 6.2.  They
reported a problem using our product on the AlphaServer 4/233.  It has
been further isolated to running with OpenVMS 6.2.

Our internal expertise has not allowed us to determine what the cause of
the problem is.  Is this something that SKY could contract with you for
to provide help in resolving this problem?  Is this something that
typically could be handled through the ASAP program? Could you please
reply to me at the address below at your earliest convenience.

Regards

Darrell

My response:

Darrell --

A couple of things aren't quite clear here. 

1)  I think the machine model would be AlphaServer xxxx 4/233, where "xxxx"
would be 2100, 1000, etc.  Please supply this information (e.g., exact model
number). 

2)  I'm a bit confused as to where it does and does not run correctly: 

"They are using DEC3000 Model 400 & Model
600 running OpenVMS 6.1 and Alphaserver 4/233 running OpenVMS 6.2.  They
reported a problem using our product on the AlphaServer 4/233.  It has
been further isolated to running with OpenVMS 6.2."

OKAY:	 DEC3000 Model 400 with OpenVMS 6.1
	 DEC3000 Model 600 with OpenVMS 6.1
Not OK:  AlphaServer 4/233 with OpenVMS 6.2

I'm missing the intent of the sentence "It has been further isolated to running
with OpenVMS 6.2." 

Is the failing platform an SMP system, by chance?  Are firmware revisions up to
rev?  Can you characterize the problem at all?  Can you reproduce this at your
site? 

We in the ASAP program don't do consulting as I believe you desire, but we're
certainly willing to answer your technical questions.  You should also feel free
to stop by out Porting Center here in Marlborough (we're in a different building
but the same campus as we were when SKY Computers visited us a few years ago). 

I'm afraid that without any details I can't help you much. 

In your communications on this issue, please mention my name and problem number
1997-3267.

Note received from developer:
--------------------------------------------------------------------------------
Thank you for your prompt reply.  I have been getting a bit of a
runaround from various groups at Digital so it is nice to have someone
reply so quickly.  The answer to the two questions you asked are as
follows:

1.  I believe the Alphaserver is a model 400

2.  As far as where the program runs, the following configurations have
been confirmed by SKY here in Chelmsford and Philips in The Netherlands

OKAY:    DEC3000 Model 400 with OpenVMS 6.1
         DEC3000 Model 600 with OpenVMS 6.1
Not OK:  AlphaServer 4/233 with OpenVMS 6.2

The following configuration has only been tested by Philips in The
Netherlands

Not OK:  DEC3000 Model 600 with OpenVMS 6.2

This does not involve an SMP system.  I don't have the exact firmware
revisions of the units in question.  The nature of the problem is that
in a AST routine that is the result of a QIO to the GK driver, we
attempt to do a read() system call to an open file.  The first time this
is done everything is fine.  The second time this is done, some of the
data returned is from the first read.  

If you have any ideas or know of someone internal/external to Digital
that might be able to help me, I would appreciate your help.

Thanks again for the prompt response.

Technical support is limited to members of the ASAP program (call 800/332-4786
to join).  I don't find a record of your membership so technically I'm not
supposed to offer you help.

That said, have you read the OpenVMS V6.2 release notes?  Section 4.11 says that
SCSI device drivers need to be modified, and it talks about what needs to be
done.

If you need access to a V6.2 system, feel free to sign up for the porting center
by calling the same phone number.  You don't need to be a member of the ASAP
program.  We can provide access to OpenVMS source listings if you need them.

Hope this helps!

Chuck;

This just came into the war room - a account you are supporting.  

I will post this as a reply to the notes stream.

By copy of this note, I am asking Donna and the porting center to call
this account and invite them to visit the porting center.  Please assess before 
making the call that we have a configuration that can meet their needs.  Do we 
have an avanti that has this rough configuration?

Chuck,

I finally have the paperwork in front of me that says our customer code
number is 131614 and our program access code is 324970. What I would
like to be able to do is have an Avanti (similar to the model I
mentioned in my previous email) with a KZPSA (PCI Differential SCSI
adapter) in it. If it had OpenVMS 6.2 and any related SCSI patches
loaded, I would like to try bringing our equipment and software, loading
it and running it. Is this something I can coordinate with you or should
I be talking to someone else.

In reference to your last email, we don't actually have our own SCSI
device driver. We use the GK (PK?) driver provide with OpenVMS
IO$_DIAGNOSE option to the QIO to pass in our own SCSI cdb. As such, I
wouldn't think we were subject to section 4.11 of the OpenVMS 6.2
Release Notes.

Looking forward to hearing from you soon

Darrell
