1771.0. "DECnet over DEFEA. " by KERNEL::LOTA () Fri Aug 04 1995 05:46

    Hi,
    
    On my ALPHA 2100 server, I'm using the FDDI interface and connect it to
    a DECconcentrator 500. On the same concentrator I have another machine
    with an FDDI card.
    
    The alpha is running VMS V6.2 and the FDDI device is DEFEA. I've
    configured DECnet over this device and can quite happily talk to the
    other node via DECnet.
    
    However, if I pull the FDDI cable out from the machine, and leave it
    out for 5 secs, and put in back in again, and try set host to other
    machine over the ring, my set host command hangs! If I fire up another
    window, and look at the information in NCP, my process hangs and goes
    into RWAST!!!
    
    The only way to clear the problem is to HALT the machine and bring it
    back up and it will keep working until such time as the FDDI cable is
    pulled out again and re-inserted.
    
    This problem was brought to my attention by a customer and I've now
    managed to reproduce it inhouse. Since then, we've had a different
    customer also highlighting the same problem, so this definately broken.
    
    I enclose some info below regarding the driver rev and such like. 
    
    
    Is there a patch to this problem? I'll be looking to get something
    offical into the system ie IPMT, so if this has been fixed please let
    me know. Otherwise, I'll IPMT the case next week.
    
    Thanks,

    I logged an IPMT on this problem and engineering fixed the problem by
    providing a new version of SYS$FRDRIVER.

    This fixed the problems we were seeing at three sites.
