6725.0. "KZPBA <=> RZ1CB-BA" by ATZIS1::PAYERHUBER () Wed May 28 1997 08:31

    Gentlemen,
    according to note 6693 there is an open issue with the kzpba (qlogic
    isp1020) and the rz1cb-ba (quantum atlas) on the dpw 500a. We have the
    same problems here. Is there any update/ solution to this problem?
    thanks in advance, fritz

    If you are having a problem ESCALATE IT or it won't get fixed.
    
    The problem in that other note is not resolved and I have not been able
    to find out why or what the exact configuration is. But the base
    configuration as shipped is supported so ask for support through proper
    channels.  IF something is found, myself or others involved, will post an
    update.

    Re .0, i'm forwarding your note to the appropriate people who are
    working on the issue.  Please advise if this is a customer unit or an
    internal one.
    
    The work-around that i have had to resort to while awaiting a
    resolution is to use another Wide SCSI adapter.  The QLogic is an
    Ultra-Wide SCSI adapter.
    
    I'm also experimenting with turning off the Ultra mode of the QLogic
    adapter to see if that would improve the behavior.  That is clearly NOT
    an acceptable resolution since one would not want to pay for an
    Ultra-Wide and to use it as a Wide.  Nevertheless, this is part of the
    steps i'm trying to help isolate the cause.  I'll post the information
    and result when i'm back in the office next week.

6725.3KZPBA/RZ1CB Incompatibility Work-AroundDECWET::VOBAMon Jun 02 1997 21:0710
    Re .2, i disabled the Ultra mode of the QLogic (KZPBA PCI-to-Ultra SCSI
    Host Adapter) using the EEROMCFG utility that came with the DPW 500a
    and the RZ1CB became fully operational (albeit non-Ultra).  To disable
    the Ultra mode, select the menu item "Enable (F)AST-10 on all devices".
    
    As i said earlier, this is NOT an acceptable resolution of the original
    problem.  It is only a work-around until the StorageWORKS and WBS folks
    could figure out what went wrong in the first place.
