Berry, it looks like you are using Layer 2 (type ethernet) with no MAC prefix assigned perhaps? Could you have more than one VM system there? You might have duplicate MAC addresses.

All guests are allowed on the vswitch with vlan 105. And they all register on the vswitch with the correct vlan and IP address. The TMR registers as: Adapter Owner: NLPTMR01 NIC: 0F00.P00 Name: DEVCLAW Porttype: Access RX Packets: 5907581 Discarded: 0 Errors: 0 TX Packets: 10793515 Discarded: 0 Errors: 0 RX Bytes: 6753504379 TX Bytes: 14545624744 Device: 0F02 Unit: 002 Role: DATA vPort: 0105 Index: 0105 VLAN: IPv4 0105 Assigned by system VLAN: IPv6 0105 Assigned by system Options: Broadcast Multicast IPv6 IPv4 VLAN Unicast IP Addresses: 161.89.54.127 MAC: 02-00-00-00-00-26 FE80::200:0:100:26 MAC: 02-00-00-00-00-26 Local Multicast IP Addresses: 224.0.0.1 MAC: 01-00-5E-00-00-01 FF02::1 MAC: 33-33-00-00-00-01 FF02::1:FF00:26 MAC: 33-33-FF-00-00-26 Local It's similar for all other guests.

Can you see all the vswitches register all the IPs? Usually when we have a problem like this its ACL's. ________________________________ From: Linux on 390 Port on behalf of van Sleeuwen, Berry Sent: Fri 10/30/2009 5:41 AM To: [email protected] Subject: Guest network connection error Hello listers, We have a group of 3 SLES8 guests running Tivoli. Two of them, TEC and TGW, have a fully functional network connection. But the third, the TMR, can't connect to the outside world. This is the case since last Friday, after a reboot of the guest. The guests run on zVM 5.4 RSU 802. The guests are connected to two VSWITCHes. One is the production network and the second is a dedicated network for TSM backup purposes. Accessing the TMR can not be done from outside the network. But we can logon to the TEC and then connect to the TMR from there. So I'd expect the connection within VM (vswitch and such) is correct. Now we are puzzeled as to how to proceed. We have been working with several groups (network, linux, VM etc) to get to the root of this problem but with no success so far. The network configs in all 3 guests are the same, other than the obvious IP addresses. We did see that a ping had been travelling through the backup network but disabling this network didn't make the production network available. Restarting the network, detach/define of the NIC etc didn't help either. Do you have any suggestions what we can do next?
