991.0. "PB Bus test 105 diagnostic error" by CSC32::L_MORSE () Wed May 28 1997 16:17

    
    	A run of Diagnostics on a Gigaswitch FDDI is done before 
    	every boot.  They see an error, "PB bus test 105" intermittently.
    
    	The box boots and runs just fine every time.   I will get
    	the exact version of module firmware if needed.
    
    	Is this something to address ?

        Where do they see this?  If the customer is doing the reboot into
    diagnostics option, then that is not intended for customer use.

       ...are you sure it isn't "BP", as in BackPlane?

991.3I will check, thanksCSC32::L_MORSEWed May 28 1997 19:136
    
    	Most likely it is BP.  Dennis M from TAC noticed this from
    	another customer.  I will get exactly how the diags are being
    	initiated, the error again and the firmware versions.

    Larry,
    
        This is the fourth time this week I have been asked the identical
    question.  From experience, I can say that when I get asked the
    identical question n times in a week when I have never been asked that
    question before, that it is the same customer.
    
        There are two different TAC Clarify calls on this (Dennis Majikas
    and Paul McSkeane, and two different CSC people who have contacted me
    about this (yourself and Marty Atkison).  The customer is a certain
    large US government/aerospace company who is running manufacturing
    tests in an unusual manner.  They are not simply doing the (unsupported
    for customers) reboot into diagnostics, they are running a sequence of
    tests through large numbers of iterations.  (also unsupported for
    customers)  After 1,000 iterations of tests, in an altitude chamber, I
    believe, it sometimes fails one of the tests.
    
        This may mean that there is a marginal problem in the backplane,
    but it is also just as likely that the diagnostics are incorrect, or
    the results are within expected variences (considering the
    circumstances).
    
        I will attempt to unify the various calls, cases, elevations and
    notes conference entries into a single customer complaint and address
    it as such.  However, I will point out that according to the normal
    prioritization of calls, this is just about as low as you can get,
    since they are not doing a supported operation, and it is not affecting
    normal operation in any way whatsoever.
    
    MDL
    
    P.S. This means you probably aren't going to see much more as a
    response in this notes conference.
991.5Failing BP Test #105 while running in diag mode.QBUS::M_ADKISONThu May 29 1997 11:4210
    My customer...Maybe the same as Larry's is issuing the following at the 
    Diag prompt--->run 100 300 /bell/halt/pass=10000 on two separate
    Gigaswith's and is failing the BP Test #105.  Individual passes work
    fine.  They are not at current SCP/FGL versions though.  SCP is 3.06 dl
    1.00 BB2.01, FGL 2's and 4's are at 3.01, CLK is at B 3.00.  I
    explained that this is not intended for customer use, yet they want to
    know if this is a known problem or not and if they can disregard this
    error.  Government site...

991.7TEST 105 FAILURESODIXIE::JOHNSTONFri May 30 1997 11:5513
    	  I have the customer with the test 105 failure after 700 to
    20,000 passes.  He has two Gigaswitches and both have this failure.
    If it turns out to be a diagnostic problem and not a hardware 
    problem, he has to know for the government what the test is doing.
    What is being tested by 105.  I need to know where to find this
    information.
    
    	  Thanks for any help you can give.

991.8Test 105???NPSS::RLEBLANCFri May 30 1997 13:109
    
    	Speaking for the GIGAswitch/FDDI FGL2, AGL2, AGL2+, FGL4 there
      is no test 105 in any mode that exists. Can you please tell what
      linecard, hardware and software this is happening on?
    
    							Thanks,

    Re: .7  (relocated from 993.0)
    
        I beg to differ.  No such definitive conclusion has been reached.
    As indicated in my previous replies, they are doing something which is
    not supported, and is not intended for customer use.
    
        The problem will be investigated in the normal manner.  If you
    don't like the prioritization, please escalate it.

991.10Diagnostic TestNNTPD::"[email protected]"John JohnstonFri May 30 1997 15:587
  I just need to know what test 105 is doing, or where I can find the info on
the
diagnostics.

991.11NPSS::MDLYONSMichael D. Lyons DTN 226-6943Fri May 30 1997 16:3411
        ...as you can see from the title, it is a backplane bus test. 
    
        There is no documentation which discusses it, user or otherwise. 
    It does not exist in the specifications, a copy of which is sitting on
    my desk.
    
        Your request will require a code search of code written many years
    ago, by engineers long gone.  This is not a simple request, and this is
    why you will not get a quick answer.

991.12NPSS::MDLYONSMichael D. Lyons DTN 226-6943Fri May 30 1997 16:399
       Let me say it once again:  they are not running tests which are
    intended for customer use.  Even if there were documentation for
    diagnostics, (which there isn't), there wouldn't be documentation for
    using it in unintended ways.
    
        I expect to see customer/field access to the reboot into
    diagnostics menu removed as a result of this problem.

991.13NPSS::MDLYONSMichael D. Lyons DTN 226-6943Fri May 30 1997 17:035
        I believe this is the "BP Bus Interface Status Reg & Control Bus
    Test", which tests that the clock responds appropriately to various
    types of errors inserted.

991.14NPSS::LIZOTTENetwork Product SupportTue Jun 03 1997 11:506
    I spoke with this customer and discouraged him from using this
    diagnostic in the manner he was with 1000 interations.  The
    GIGAswitch/FDDI instalation manual on Page A-8 describes the use of
    these diags with a pass count of 10.  I'll work the customer issue
    through the proper channels.  Tom L NPB TAC.
