2413.0. "900EF random resets... why" by NCMAIL::SCHEID () Thu Jun 22 1995 15:08

    
    I have a customer who has approx 50+ DECswitch 900MX/EFs distributed 
    amongst 10+ DEChub 900MS. They use these 900MX/EFs as PE devices to
    connect dedicated High powered SUN workstations.  All 900 MS Backplanes
    with 900EFs are interconnected to (2) Gigaswitch/FDDI This environment has
    been extremely stable for well over 6 months. 
    
    Recently in the last 10 Days the customer has been getting via DECMCC --
    Unsolicted resets messages from a large number of 900EFs (between 15-20).
    HUBwatch has verified that indeed the bridges did reset. The only 
    thing that has changed in this last 10 days is that both Gigaswitches 
    have had the ARP Server functionality enabled on them. 
    
    
    What is a unsolicted reset of a 900EF and what could cause this ???
    
    I have cross posted this note in the Gigaswitch notes conference 
    
    
    900MX/EF are running V1.4 firmware
    900MS    are running v3.1 MAM code
    Gigaswitch is running V2.2 firmware
    
    Any help would be appreciated

    Charlie an unsolicited reset is basically a reset caused by a fatal
    error, or another way of putting it is it's a crash.
    
    >900MX/EF are running V1.4 firmware
    >900MS    are running v3.1 MAM code
    >Gigaswitch is running V2.2 firmware
    
    Any idea of the customer's future intention of upgrading firmware
    to wave 3 baselevel?
    There were some bugs fixed in the 900MX/EF V1.4 code that may or
    may not be related to your customers problem. Without alot of evidence
    from you customer's site as to network config details, counters, 
    error logs, etc. etc., it would dificult in guessing as to what is going 
    wrong at your customer's site.
    I don't have any idea what the ARP server functionality being enabled
    is doing to the MX's/EF's (I don't even know what it is), so you will 
    have to get a definitive answer in the Gigaswitch conference.
    However it does seem curious that there appears to be a coincident
    reaction ( unsolicited resets) to the action of enabling this function
    in the Gigaswitches.

2413.2important upgrade proceduresNETCAD::CURRIERThu Jun 22 1995 17:3517
    When  you customer upgrades the hubs...
    
    1st upgrade at least 1 hubwatch station
    
    2nd upgrade the management agent
    
    3rd upgrade the devices
    
    VERY 1st OF ALL  read the release notes that come with the agent code
    
    DO NOT use old hubwatch to manage new mam & devices
    
    DO NOT use new hubwatch to manage old mam & devices
    
    mam & devices MUST be BOTH new or BOTH old ..  NO mixing
    
    
2413.3No upgrades have been performedNCMAIL::SCHEIDThu Jun 22 1995 17:585
    
    No upgrades have been performed ... everything has been running at the
    current released level of firmware ...

    Take a look at the DEFBA error logs:  From the DEChub console
    redirect to each slot containing a DEFBA and look at the error log
    entries.  The 1st piece of information to get is the "Error code" field.

    There are known reset problems that have been fixed in DEFBA 1.5.
