1736.0. "Transmission failure when upgrading DECagent 90?" by TENNIS::KAM (Kam USDS (714)261-4133 (DTN 535) IVO) Tue Nov 29 1994 18:49

    We're trying to upgrade our DECagent 90 from V1.0 to the latest.
    
    We power-cycled the DECagent 90 and via a terminal starting CTRL Iing
    until it responded with CCI>
    
    The following occurred:
    
    CCI> load denma_load.sys
    
    DENMA -901- Initializing DECagent 90
    DENMA -953- Attempting to locate load host
    {ISO8802]
    
    DENMA -915- Transmission failure after ten attempts
    DENMA -952- Verify network connection and restart the DECagent 90.
    
    What does all this mean?
    
    The DECagent 90 is in a DEChub 90 and has or appears to be working
    fine.  We've been using it since around 17-Nov-1992.
    
    We ran REPLY/ENABLE=NET on an OpenVMS machine and we didn't see any
    request via the net.  It responds with the transmission failure
    IMMEDIATELY.
    
    Any hints?

1736.1Need to enable circuit service on the VAXROGER::GAUDETBecause the Earth is 2/3 waterTue Nov 29 1994 20:5421
Check the following:

$ NCP SHOW KNOWN CIRCUITS CHAR

You must have "Service = enabled" in order for the VAX to respond to the load
request.  If you do not, do the following (assume network circuit is QNA-0):

$ MCR NCP
NCP>SET CIRCUIT QNA-0 STATE OFF
NCP>SET CIRCUIT QNA-0 SERVICE ENABLE
NCP>SET CIRCUIT QNA-0 STATE ON
NCP>EXIT

NOTE: This will temporarily disconnect you from the network, so (1) do it quick
or, (2) put the above commands in a command file and execute (@) it.  I do this
all the time and never lose network connectivity.

I think you already know this, but REPLY/ENABLE=NET does not enable the network
service.  It only enables the logging of OPCOM messages to the VAX console.

    I believe it is and here is the files in MOM$LOAD.  Everything looks
    correct.  Am I missing something?

    Shouldn't I be able to see the request and the results of that request? 
    When I boot satelites I do.

1736.3still no luckTENNIS::KAMKam USDS (714)261-4133 (DTN 535) IVOWed Nov 30 1994 15:4511
    Does the device have to be set back to the factory default e.g., NO
    PASSWORD?  I tried that and it didn't appear to work.
    
    At the CCI prompt when I do a load DENMA_LOAD.SYS shouldn't I see a MOM
    request?
    
    Maybe my device is defective.

1736.4Strange problem ... let's see what the ROM version isROGER::GAUDETBecause the Earth is 2/3 waterWed Nov 30 1994 16:4038
The console password has no effect on the downline load process, so a
reset-to-factory is not required.

You should see the request at the VAX console when it is issued by the DECagent.
However, this does not happen immediately after the LOAD DENMA_LOAD.SYS command
is issued.  The DECagent first requests an IEEE ISO8802 load (please don't ask,
it's just the way it was implemented in the ROM code).  Then after 10 seconds or
so, it attempts an Ethernet load.  At this point, if your VAX is configured to
accept requests (which is looks like it is) you should see the message on the
VAX console that a request has been made by the DECagent.

According to your base note, it does not seem to be getting beyond the ISO8802
load request.  I am not sure why.  Are you sure the network connection is OK? 
DEChub 90 has a terminator on the side of the hub, etc. etc.?  I have never seen
a case where it did not at least attempt an Ethernet load after the ISO8802 load.

Here is what a successful load should look like:

CCI>load denma_load.sys

DENMA -901- Initializing DECagent 90.
DENMA -953- Attempting to locate load host
[ISO8802]
DENMA -953- Attempting to locate load host
[ETHERNET]
DENMA -955- Host AA-00-04-00-B1-F0 located [ETHERNET]
DENMA -956- Requesting load from host AA-00-04-00-B1-F0
DENMA -903- Loading from host AA-00-04-00-B1-F0
DENMA -904- Image verification in progress.
DENMA -905- Image load completed.

%CCI-I-CRCCHK,attempting CRC check on image loaded
CCI>

One last thing.  Can you tell me what the output of the CCI> SHOW SERVER command
says on this DECagent?

1736.5I conclude that the device is defectiveTENNIS::KAMKam USDS (714)261-4133 (DTN 535) IVOWed Nov 30 1994 17:3523
    CCI> show server provides the following in abbreviated format:
    current hardware revision D01
    current LANCE revision F
    current romcode revision BL05.00
    
    Something must be wrong with the DECagent 90.  I borrow a DECagent 90
    from the IS folks locally.  However, there firmware was at V1.1.  So I
    didn't need step 1.4 e.g., load denma_load.sys.  At NCP I just did a
    LOAD NODE DENMA and after a few brain dead mistakes on my part it worked 
    and provided the menus according to the on-line documentation.
    
    My conclusion is that I purchased this from Bill Seavers in November
    1992 and I believe that it must of been an Engineering prototype or
    something.  In most cases it works but not the downloading.  I'm trying
    to get the local FS to replace it.
    
    I don't think it's me and it's got to be the device.
    
    Thanks for the support.

1736.6May be too late, but...ROGER::GAUDETBecause the Earth is 2/3 waterMon Dec 19 1994 16:276
To follow up on this note and note 1794, I had one other thought.  Is it
possible that there is a bridge located between the DECagent and the load host
that is filtering the MOP protocol (60-01 and 60-02)?  That's my last-ditch
guess as to why the load host would not be responding to the load requests.
