1113.0. "Firmware compatability/CIXCD rev 8?" by CRLRFR::BLUNT () Thu Feb 20 1997 09:25

    
    We've received info that indicates that CIXCD Microcode Rev 8 may have
    problems, and is being withdrawn.  We had just gone thru the latest
    firware CD (version 3.8, I think), and updated everything to the most
    recent firmware.  If we downgrade to Rev 7 CIXCD Microcode, will we
    have any conflicts or issues with the OTHER versions we have loaded?

    Bob;
    
    The word I heard is don't use V8 or V7 or V6 of the CIXCD uCode.
    Drop back to V5 of the CIXCD uCode until they understand what the
    issue is with V8.
    
    This is what we have done for one of our large cluster sites who
    had some of the INVEXCPTN's in PNdriver w/ R2 being f-f's.
    
    Hope this helps.

    This is case of availible data. We have three customers that upgraded
    from V5 to V8 and then fell back to V5.  I am working on validating an
    hypothisis that a change made to V8 is the cause. We have not been able
    to recreate the problem internally and would not expect a customer to
    put his business at risk needlessly to vslidate a fix.  I have a report
    of a site that used V6, V7 & V8 without problems.  The recomendation is
    to fallback to your last stable revision.
    
    There are no version conflict problems known between different versions
    of the CIXCD firmware, versions of the console, version of any other
    option or versions of the pndriver.  Please see the CLUSTER notes file
    for news.
    
    Please send me updates on you experience with V8, V7 or V6

    Mail is fine.
