773.0. "FYI - intdiv divide by zero error" by CSC32::R_ROBERTSON () Wed Feb 05 1997 16:09

    New twist on the -intdiv divide by zero error.
    We had a RW536 with a "semi-bad" AC module cause these errors.
    Any platter we tried to mount gave the %mount-f-intdiv
    error. Config 40 was set to off. V3.3-1 OSMS VMS5.5-2.
    MCR SCSI doing inquire on the jukebox showed ...? instead
    of ...DEC RW516 . We changed config 40 to on(hp mode instead
    of DEC mode), inquire showed ...HP C1715t, then all the
    platters would mount just fine.

    This was most likely due to the fact that the VMS I/O function
    PACKACK causes a SCSI INQUIRY command to happen and if it
    fails the SCSI READ_CAPACITY was not called so the geometry
    information was not available.  This lead to the divide by
    zero in INIT.
    
    Good data point Robby, the people that try to isolate problem
    causes need to see the variation of things that cause this
    kind of problem.
