IT Assistant not showing servers

I have a site of around 27 Dell servers and have noticed that three of the servers are not showing up in IT Assistant.
I am running IT Assistant 8 on Windows 2000 server

OpenManage is installed and operational on the three invisible servers and snmp is running correctly. Sometimes when I perform an discovery they show up randomly but then vanish about 10 seconds later.

The invisible machines are either Windows 2000 server or Linux AS4. They have either OpenManage 1.9.2 or 5.1 installed.

How do I go about resolving this issue. I have gone through trouble shooting and They test fine. Is there a inventory log?

Paul

    Paul:  When you run the SNMP troubleshooting test look at the 3rd check mark (I am assuming they are all green).  Does it show an agent version?  You will probably see most of the mibs that it walks as NA but it should return an agent version. 
     
    Are these 3 servers in a DMZ or edge network?  They could be marked as down if status polling fails, for ITA to Monitor the servers port 7 needs to be open for ping and the snmp ports 161 and 162. (other ports are required for software updates, etc, these are the bare minimum)
     
    Installation and Security Guide:
     
    You can enable ITA verbose logging, then force another discovery.  If you do enable verbose logging don't forget to turn it off!!
     
    To enable logging of ITA,
    1.  Stop the ITA services. 
    2.  Edit c:\program files\dell\openmanage\it assistant\configuration\dconfig.ini.
    3.  Look for the GUI header and comment out the entry INFO_LOGGING=N. (semi colon is the   comment char)
    4.  Create a new line INFO_LOGGING=Y FS;I;C:\italogs\.log  (you can change this to D,E, whatever you choose)
    5.  Restart the ITA services.  This will create 2 files at the specified location named dcnetmon.log and dcappsrv.log.
    6.  Force another discovery.  Allow it to to finish.
    7.  Stop the ITA services.
    8.  Edit the c:\program files\dell\openmanage\it assistant\configuration\dconfig.ini uncomment INFO_LOGGING=N
       and comment out the INFO_LOGGING=Y line.
    9.  Start the ITA services.
    10. Analyze the logs for any indication of the problem.

    Looks like one of the machines has a broken snmp data. No dell information is showing. The other two have started to show correctly (Did some DNS tweaks last night). will try and uninstall and reinstall of openmanage.

    Thanks for your help for the tracking information.

    Hmm, I would be interested in looking at your network.  Can you call in?

    Update.
    Have resolved one of the servers and it is now showing correctly. The other two servers are running Server 2000. Have updated to latest drivers, firmware and OpenManage. When I do a scan and inventory they sometimes show up for around 30 seconds then vanish. When I do a troubleshoot it looks fine and is pingable and snmp work fine as well (incl dell extensions).

    Have done logging and can see them being added fine but can't see anything why its being removed.

    Is there any more information I can supply?

    Woohoo. Hopefully success.
    Those machines had vmware network devices listed. Disabled the other Vmware network devices (and ip's) and seems to be fine now.

    I am guessing that when doing a ip discovery it would find them but sometimes it would do an snmp query on IP addresses. If it got one of the alternative IP's it would be unable to do a DNS query on it and it would then remove it. The logs showed the actually ip listed after the virtual network devices.

    interesting.  I sent your findings to the dev group for analysis.
