Beep sound is coming in very 3 mins in Alpha Open VMS Machine problem.

I have 5 Alpha DS10 Open VMS machine (VMS version 7.2-1) connected in network through switch.They are not communicating with each other.But all of them are connected to a master server that is also Alpha DS10 machine connected with the 5 other machines in LAN (10 mbps).
A beep sound is coming from the 5 machines
at an average of 3 mins interval.In one of the machine I got the following message.

EVENTUID:61DA3619-6F53-11E0-FE7-4E42304F4333
Reject received from: node local Nb0oc3 is NSP LOCAL NSAP.
Reason=No resoueces.

I guess it may be a problem in a network card in motherboard but not uet confirmed.
Can some body help me out in finding the problem?

Can you show us the output of

$ mcr ncl show nsp all

I am having the Operator log from the machine.I am attaching that too for your referrence.I am also sending you the required information with in a short while.

Re: Beep sound is coming in very 3 mins in Alpha Open VMS Machine problem.

I am not sure this is related but in your operator log i see:

Event: Carrier Check Failure from: Node LOCAL:.NB0OC3 CSMA-CD Station CSMACD-1

It looks like this system has two ethernet interfaces but only one is connected.

If that is the case you can disable the second circuit with the command:

$ mcr ncl disable routing circuit csmacd-1

You can make this change permanent by running the sys$manager:net$configure.com script. Use "ADVANCED" as parameter. Select option 3 (configure devices) and enter "NONE" as data link name to use for the second ethernet interface.

Re: Beep sound is coming in very 3 mins in Alpha Open VMS Machine problem.

This message has came up at the time of disconnection with LAN.Infact we have removed the one of the LAN for testing purpose.What we found is that, when it one of the 2 LAN cable is removed from DS10 network card the sound vanishes.
So we are thinking of replacing the switch through which the maciches are connected.Wiil it be a good idea?

Re: Beep sound is coming in very 3 mins in Alpha Open VMS Machine problem.

Anjan,

some program on your local node tries to communicate with some program on a remote node and the connection is being rejected by the remote transport service provider due to insufficient resources on the remote system.

The DECnet Phase IV address of the local node is 1.751, the address of the remote node is 1.755.

You need to find out, which 'resource' is missing on node 1.755.

Try some simple SET HOST 1.nnn commands between your 5 Alphas to determine, which node can talk to which other node.

No, the 'Reject received' message indicates, that the connect request has been REJECTED by the remote node. This proves, that the network packet travelled to the remote node and then another packet came back to the LOCAL node. Once you understand this situation, why would you want to replace the network switch ?

Volker,
many thanks for your suggestion.
Now I am also confirmned that replacing the switch will not server the purpose.

I have made set host from every machine.
But for 1.755, I am not able to log in.
It says "%SYSTEM-F-REMRSRC%,
Insufficient system resource at remote node"

Cau u please tell me How can I identify which Machine actually it is?
The Machines support TCPIP as well as Decnet.
Foer TCPIP I can find it from UCX show host command.

But for DEcnet I don't no how to see the machine name through DEcnet Id.Also please suggest me How can I identify the which resource is insufficient?

Re: Beep sound is coming in very 3 mins in Alpha Open VMS Machine problem.

Anjan,

login via TELNET to all your OpenVMS nodes and issue:

$ SHOW NETWORK

This should tell you the DECnet Adresses of each node. You can also use:

$ MC NCL SHOW ROUTING PhaseIV Address

Then you can build a picture of the nodes and their DECnet addresses.

As you've found out, there seems to be some resource problem on node 1.755. If you can login with TELNET, but not with SET HOST, this indicates, that the 'resource problem' is within DECnet and not within the overall OpenVMS system. Check OPERATOR.LOG on node 1.755 for any error messages in conjunction with a failed SET HOST attempt.

Try a MC NCL SHOW NSP ALL - what is the value of the 'Currently Active Connections' counter ?

Anjan,

also try Google for 'set host REMRSRC'

If it's an overall OpenVMS system resource problem, you won't be able to login via TELNET as well.

Volker,

I have found the machine by SHOW NETWORK.I am able to Telnet to the machine too.
I have captured the latest operator log and
mc ncl show nsp all output.Both I am attaching.

I found the machine is in hanged condition and not able to do anything on it by key board or mouse.So given a restart. Interestingly, the beep sound vanishes after the restart for all the other machines.

Anjan,

that's what I suspected. That node was somehow 'hung'. I assume the OPERATOR.LOG and NCL output was generated AFTER you booted the node and the problem was gone ...

So you've solved the immediate problem by a reboot, but you have not learned, what the real problem was.

Instead of a boot, you could have forced a system crash (halt the machine, then type >>> CRASH). This would have provided the opportunity to find the real problem in the sysdump dump file.

Anjan,

you should also check the LAN connection of CSMACD-0, which has reported a couple of carrier check failures.

Thanks a lot for the valuable suggestion.

Yes you are right that I could have given a crash before the reboot that I have done earlier too.But some out it did not come in my mind and thus I lost the exact information.Next time I keep this in my mind definitely.

I've seen this scenario a number of times.

Each time it was non-paged pool that was exhausted, and it had already been expanded to its maximum size.

In SDA, CLUE MEM/STAT will show you the details.

I have captured the output.But don't see any abnormality as per my knowledge.Can u highlight me if there is any abnormality.

Re: Beep sound is coming in very 3 mins in Alpha Open VMS Machine problem.

Anjan,

you only need to worry about nonpaged pool, if any of the Unsuccessful/Failure counters of SDA> CLUE MEM/STAT are greater than 0.

If you had forced a crash, you could have checked these counter in the system dump as well (with the same command).

Volkar,

I have gone through about non paged pools.
Can u please tell me from what we can determine from working sets and non paged pools?
It may sounds silly but it will have a
greate help to me.
