Is this a hardware problem or not ?

Hi group,


Sorry for the long post, but I'm really annoyed with this problem.

Since monday morning , one of our AS/400 fails to communicate with the other 2
systems using TCP/IP & SNA over the Tokenring.
Traffic over the tokenring between these last two is working perfectly.
Ethernet between the 3 machines is working perfectly as well.
The IP-Tokenring traffic is needed by MIMIX.
The system with the problem is our HUB-system.

These are the Communication Resources from the failing system :

    Resource        Type  Status                Text
    CMB01           9164  Operational           Combined function IOP
      LIN04         2720  Operational           Comm Adapter
        LIN011      2720  Operational           V.24 Port
      LIN02         2721  Operational           Comm Adapter
        LIN012      2721  Operational           Comm Port
        CMN05       2721  Operational           Comm Port
      LIN05         2850  Operational           File Server IOA
        CMN06       2838  Operational           Ethernet Port
        CMN01       2724  Operational           Token-Ring Port    
        CMN07       6B00  Operational           Virtual Port
      LIN06         285A  Operational           LAN Adapter
    CMB02           2809  Operational           Combined function IOP
      LIN03         2838  Operational           LAN Adapter
        CMN04       2838  Operational           Ethernet Port      <== eth cmn


If I stop and restart the *NWS (LIN05), 
SNDNETMSG/STRPASTHR & PING starts to work again over the Tokenring. 
The ping response times are varying between 1ms and above 1sec.
Using an FTP-session or a SNDNETF to transfer some data, 
all communications suddenly stops in the middle of the process
with no errors whatsoever. 
(QSNADS jobs have now a status of "ICFW" , Pings don't give any result anymore)
I even tried the Windows trick ( re-IPL :-) the system ) , still no luck.

During these 4 days I've called Hardware support, Software support and again
Hardware support and yes again Software support. Well you get the idea :-(


in SST I found the following around the time that we manually IPLd the system
over the weekend :

 Message . . . . :   *Attention*  Hardware service may be required.
 Cause . . . . . :   Internal analysis of a hardware exception indicates
that the system may require the attention of your service provider.
 Recovery  . . . :   Contact your hardware service provider.  The steps
below may be performed to attempt to return to normal operations:
     1) Vary off any failed configuration descriptions.  Then vary them on.
     2) If processor &26 is still not operable and DASD is attached, IPL the
   system to start the processor. If DASD is not attached, perform "VRYCFG
   RESET(*YES)" to start the processor.
     Press F14 and report the problem.

Am I correct when I think that this indicates a hardware error on the 
"File Server IOA" ?


Any thoughts are really appreciated.


Many TNX in advance,



Chris
