    Network Issues after Upgrade to VI3

    ssandmann Enthusiast

       

      Hello Community!

       

       

      This weekend i upgraded two ESX Servers from 2.5.2 to 3.0.2... Everything went fine, no Problems with the Upgrade...

       

       

      But today we have Problems with our Fileserver (w2000 VM)... When Users open some of their Applications which have temp files on the Fileserver, the writing on the Fileserver hangs or the Network fails...

       

       

      We are not really sure what it is but it started after the Upgrade... Is the Network perhaps overloaded? VM's share one gbit Nic...

       

       

      This is our Environment:

       

       

      2x ESX 3.0.2 on IBM x366 with each 4x 3,6Ghz CPU's 2x HBA's 2 NIC's

       

       

      SAN Storage is a DS6800 from IBM with two Switches in the Middle...

       

       

       

       

       

      We never hab this Problems before...We also checked the logs, but couldn't find anything...

       

       

      We are not sure but think that there might be a network or i/o issue...

       

       

       

       

       

      I hope somebody has got an Idea!

       

       

      If you need more Info please ask...

       

       

      Thanks in advance!

       

       

      Kind regards

          It might help if you would post the output of the following command:

           

          #esxcfg-vswitch -l

           

          #esx-cfg-vswif -l

           

          #esxcfg-nics -l

           

          Once we take a look at these, we might be able to point you in the right direction.  Or, hopefully, someone else may know the problem/solution off the top of their head  : - )

            And read the following thread Severe network performance issues, there are some possible solutions in it.

            This post 3.0.1 --> 3.0.2 upgrade disk performance drops 84% seems to be relevant as well.

                Are the fileserver VM's virtual nics connected to the VM-Net portgroup?

                  Not yet...

                   

                   

                  I just created that group but we have to wait for the firewall team to allow Traffic on that port... (and there is no cable plugged in yet)

                   

                   

                  Before the upgrade everything was fine ... (console on one port vm's on the other...)

                   

                   

                  I really not sure if it is the network... but in the windows events there are some error like "while saving file x the connection was lost, data may be lost"... It seems that the vm just cuts off the network when i.e. Lotus is not reading or writing...

                   

                   

                  It seems like it is a kind of timeout...

                    Have you tried using the Intel NIC's? I have had some very strange 'occurrences' with Broadcom's.

                     

                     

                     

                     

                     

                    Just a thought.
