Hi Folks! I have a very strange problem on a client here. We had a zVM 5.4 running flawlessly, with vswitch and vlan tagging. Yesterday we updated zVM to 6.1. Even this being a big change, it was the only change we did. We had a gateway machine, lnxadm, with a eth0 coupled to a vswitch (VADM) on VLAN 812. If we try to ping the gateway, we get an "Destination Host Unreachable".
We have other linuxes on the same environmente, and we can ssh to any of them, without any problem. This is our environment: CP Q NIC DET Adapter 0700.P00 Type: QDIO Name: UNASSIGNED Devices: 3 MAC: 02-00-00-00-00-04 VSWITCH: SYSTEM VADM RX Packets: 5 Discarded: 0 Errors: 0 TX Packets: 39 Discarded: 18 Errors: 0 RX Bytes: 320 TX Bytes: 2226 Connection Name: HALLOLE State: Session Established Device: 0700 Unit: 000 Role: CTL-READ Device: 0701 Unit: 001 Role: CTL-WRITE Device: 0702 Unit: 002 Role: DATA vPort: 0081 Index: 0081 VLAN: 0812 Options: Ethernet Broadcast Unicast MAC Addresses: 02-00-00-00-00-04 Multicast MAC Addresses: 01-00-5E-00-00-01 33-33-00-00-00-01 33-33-FF-00-00-04 ifconfig eth0 eth0 Link encap:Ethernet HWaddr 02:00:00:00:00:04 inet addr:10.9.49.15 Bcast:10.9.49.255 Mask:255.255.255.0 inet6 addr: fe80::ff:fe00:4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:57 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:3258 (3.1 KiB) cat /etc/sysconfig/network-scripts/ifcfg-eth0 # IBM QETH DEVICE=eth0 ARP=yes OPTIONS="layer2=1" BOOTPROTO=none IPADDR=10.9.49.15 NETMASK=255.255.255.0 NETTYPE=qeth ONBOOT=yes SUBCHANNELS=0.0.0700,0.0.0701,0.0.0702 TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes CP Q LAN VADM DET VSWITCH SYSTEM VADM Type: VSWITCH Connected: 14 Maxconn: INFINITE PERSISTENT RESTRICTED ETHERNET Accounting: OFF VLAN Aware Default VLAN: 0812 Default Porttype: Trunk GVRP: Enabled Native VLAN: 0001 VLAN Counters: OFF MAC address: 02-00-00-00-00-01 State: Ready IPTimeout: 5 QueueStorage: 8 Isolation Status: OFF RDEV: 8003.P00 VDEV: 8003 Controller: DTCVSW1 RDEV: 8006.P00 VDEV: 8006 Controller: DTCVSW2 BACKUP Adapter Connections: Adapter Owner: LNXADM NIC: 0700.P00 Name: UNASSIGNED Porttype: Trunk RX Packets: 5 Discarded: 0 Errors: 0 TX Packets: 39 Discarded: 18 Errors: 0 RX Bytes: 320 TX Bytes: 2226 Device: 0702 Unit: 002 Role: DATA vPort: 0081 Index: 0081 VLAN: 0812 Options: Ethernet Broadcast Unicast MAC Addresses: 02-00-00-00-00-04 Multicast MAC Addresses: 01-00-5E-00-00-01 33-33-00-00-00-01 33-33-FF-00-00-04 CP Q VSWITCH VADM DET VSWITCH SYSTEM VADM Type: VSWITCH Connected: 14 Maxconn: INFINITE PERSISTENT RESTRICTED ETHERNET Accounting: OFF VLAN Aware Default VLAN: 0812 Default Porttype: Trunk GVRP: Enabled Native VLAN: 0001 VLAN Counters: OFF MAC address: 02-00-00-00-00-01 State: Ready IPTimeout: 5 QueueStorage: 8 Isolation Status: OFF RDEV: 8003.P00 VDEV: 8003 Controller: DTCVSW1 VSWITCH Connection: RX Packets: 1058558 Discarded: 2642 Errors: 0 TX Packets: 830546 Discarded: 0 Errors: 0 RX Bytes: 477088169 TX Bytes: 264909169 Device: 8003 Unit: 000 Role: DATA vPort: 0001 Index: 0001 Unicast IP Addresses: 10.9.49.1 MAC: 00-04-23-AD-42-1A Remote RDEV: 8006.P00 VDEV: 8006 Controller: DTCVSW2 BACKUP Adapter Connections: Adapter Owner: LNXADM NIC: 0700.P00 Name: UNASSIGNED Porttype: Trunk RX Packets: 5 Discarded: 0 Errors: 0 TX Packets: 39 Discarded: 18 Errors: 0 RX Bytes: 320 TX Bytes: 2226 Device: 0702 Unit: 002 Role: DATA vPort: 0081 Index: 0081 VLAN: 0812 Options: Ethernet Broadcast Unicast MAC Addresses: 02-00-00-00-00-04 Multicast MAC Addresses: 01-00-5E-00-00-01 33-33-00-00-00-01 33-33-FF-00-00-04 CP Q VSWITCH VADM ACC VSWITCH SYSTEM VADM Type: VSWITCH Connected: 14 Maxconn: INFINITE PERSISTENT RESTRICTED ETHERNET Accounting: OFF VLAN Aware Default VLAN: 0812 Default Porttype: Trunk GVRP: Enabled Native VLAN: 0001 VLAN Counters: OFF MAC address: 02-00-00-00-00-01 State: Ready IPTimeout: 5 QueueStorage: 8 Isolation Status: OFF Authorized userids: LNXADM Porttype: Trunk VLAN: 0812 Mauro http://mauro.limeiratem.com - registered Linux User: 294521 Scripture is both history, and a love letter from God. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
