Thread: broken monitor, well sort of

  1. broken monitor, well sort of

    Hi

    strange one.


    if I type

    monitor sys/node=(ca0390, ca0350)

    Monitor starts up and then falls over with:

    %MONITOR-E-UNEXPERR, unexpected error
    -SYSTEM-F-FLTDIV_F, arithmetic fault, floating divide by zero at
    PC=000000000005
    BBE8, PS=0000001B


    If I type

    monitor sys/node=(ca0350, ca0390)

    then it works fine

    Any suggestions?

    Antony,

    there does not appear to exist any patch for MONITOR (i.e.
    MONITOR.EXE, MONTORSHR.EXE or SPISHR.EXE) for OpenVMS Alpha V7.3-2.

    As OpenVMS Alpha V7.3-2 is out of support, no fixes can be expected.

    You could try a SET PROC/DUMP and have a look at the process dump to
    find out, which instruction causes this floating point divide error.

    Are those 2 nodes, you're trying to monitor, Alpha or VAX nodes ?

    Volker.


  3. Re: broken monitor, well sort of

    Antony,

    MONITOR on V7.3-2 is still a VAX translated image (MONITOR_TV.EXE).

    This seems to be the instruction stream taking the FLTDIV_F fault:

    MONITOR_TV+5BBC4: LDT F5,#X0018(FP) < load F5
    MONITOR_TV+5BBC8: CVTQF F5,F5 < convert F5
    MONITOR_TV+5BBCC: LDAH R17,#X000B(R15)
    MONITOR_TV+5BBD0: LDF F17,#XA5F4(R17)
    MONITOR_TV+5BBD4: DIVF/U F5,F17,F18
    MONITOR_TV+5BBD8: TRAPB
    MONITOR_TV+5BBDC: CPYS F18,F18,F5 < copy F18
    into F5
    MONITOR_TV+5BBE0: S4ADDL R1,R2,R18
    MONITOR_TV+5BBE4: DIVF/U F4,F5,F19 < divide by
    R5 (r5=0)
    MONITOR_TV+5BBE8: TRAPB < report
    fault here

    Don't expect anyone willing to dig into that translated image.

    You've found a workaround. Use it...

    Volker.

    Current Version Support did end earlier this year.

    V7.3-2 Prior Version Support is expected through through 2011, and
    thereafter only with advanced notice of 24 months. This on both of the
    posted PVS policies; in both the European Geography and the US & AP
    Geography policies.

    Which means that there can still be fixes seen for OpenVMS Alpha V7.3-2,
    for customer folks with PVS contracts.

    kiwi-red: If you have a prior version support (PVS) contract, call up HP
    and report the bug. And Volker is correct; I'd certainly also expect to
    use the workaround for a while.

    I'd also look at loading mandatory ECOs for the core OpenVMS Alpha
    V7.3-2 components, on the off chance that this error is arising from an
    underlying library or operating system component and not from within the
    images of the translated MONITOR itself.

    MONITOR was re-written for the next release after this version; the use
    of the translator and the existing MONITOR code was eliminated. The
    updated version of MONITOR can be found in the V8.* range of OpenVMS
    releases.

    Steve,

    I maybe should have said:

    As OpenVMS Alpha V7.3-2 is out of support, no PUBLIC fixes can be
    expected.

    Volker.

    Maybe. But I expect, that fixes for a PVS paying customer will get
    PUBLIC afterwards also...

  7. Re: broken monitor, well sort of

    Thanks guys,

    I have asked my local support guy, Sek, in oz and he is looking at it.
    I assume we are supported, as we keep paying the bills ;-)

    FWIW, it is two Alpha's. Looking at rolling out Update 12 in the next
    month or so on Non prod and then see if we can get it in to
    production.


    Cheers

    Ironically, folks had the same complaints when the Customer Support
    Center in Atlanta first opened up -- folks said they couldn't understand
    the Southern accent. Some folks even hung up the phone if they were
    connected to a person with a Southern accent. But people learned, over
    time, to understand and appreciate each other.

    I grew up in a college town with students from all over the world, and
    grew to understand (and even enjoy) the variety of English accents.

    I taught a seminar for the DECUS user group in Budapest in 2004. They
    were only 10 years or so out of Communist rule and most adults (who
    already knew Hungarian and Russian) had already learned English as well.
    They said if I could have spoken English with a German or French accent
    they could have understood me better, but my American accent was too
    different and hard to understand. They had my respect and my sympathy,
    and we did the best we could together.

    Um, Keith?

    There's rather a difference between vernacular and culture, and people knowing
    the product lines, and so on. The language issue is merely a symptom of far
    deeper issue.

    HP needs to take a lesson from Dell and start pulling support back on-shore.

    Likewise, I find it a welcome challenge at such events as the VMS Bootcamp and
    "DECUS" Symposia where we talk to/with folks from darn near everywhere. At least
    we all know the products. Culture issues are not major, and the language issue
    merely a challenge.

    I spent two weeks at a time in England three times between Jan and Jun of 1984
    for work. I came home sounding like a cross between and Yank and a Brit. Lasted
    for couple weeks at home, until I re-adjusted myself to talking to everyone in
    the local vernacular with a non-British manner.
