1121.0. "Line status OK bu no connection..." by 52410::STRATMAN (Peter Stratman @VBO) Tue Dec 12 1995 09:21

I have the following strange case:

A node is connected to a DECserver 90M, TCP/IP listener 2001
and this is defined in PCM. The DECserver is available from the PCM
system, because I can TELNET to its console port. I can also TELNET to
the server using listener 2001, and this connects me to the console.


From PCM I cannot connect though, although this HAS worked for a long time
already. Although CONSOLE STAT gives me a "Line status : OK" state, there is no
user connected to the DECserver, and all commands concerning this node hang
(including from the C3 which ACCVIOs).

Any ideas where to look ?

Thanks,
Peter.

All the monitored systems of this one controller seem to cause the hang.

Only one of the BG device sockets is in the following state:

UCX> sho dev/full bg39
Device_socket: bg39        Type: STREAM      LOCAL               REMOTE
                              Port:           1041                 2001

Is the CANTRECVMORE a problem ? What can I do about it ?

Thanks,

    Is the controller stuck in LEF? I would bet that it is. If so,
    go into SDA and do
    
    SDA> SET PROCESS/INDEX=index-number-of-controller
    SDA> SHO CALL
    SDA> SHO PROC/CHANNEL
    
    If this is a VAX then also do:
    
    SDA> SHO DEV/ADDR=@R5
    
    The BG device in that state indicates that the socket is not being
    read. This could be becuase the controller is stuck elsehwere and not
    reading the socket.

      Dan

    Dan,

    I'm afraid that I couldn't do what you suggested in .-1 because PCM
    was rebooted before. What I did notice though was that the controller
    which connects to the BG device I listed in .1 also controlled 2
    systems which were defined as using the same listener on the same
    server. Ho wPCM could have gotten in this state is a mystery to me
    since the editor disables the systems in that case. Anyway, after
    correcting this and restarting PCM the problem went away.


    BTW, everything was stuck, so I stopped all processes. I then got stuck
    because the global section was still around to make PCM think that
    it was still running. HOW can I remove that global section "by hand" ?

    Thanks,
    Peter.
