昨晚第一次透過Web連進vCenter Server Appliance，看一看相關資訊後，웹을 통해 직접 업데이트 패치를 할 수 있다는 것을 발견하고，바로 클릭했다。업데이트가 완료된 후，화면에 다시 시작이 필요하다는 메시지가 표시되었고，vCenter Server Appliance를 재부팅한 후，다음 메시지가 나타났다”네트워크가 감지되지 않았습니다. 로그인 후 /opt/vmware/share/vami/vami_config_net 명령을 실행하여 네트워크를 구성하십시오”的錯誤訊息。
上網咕狗，很快找到官方的KB，正當開心KB所描述的情形跟我一模模一樣樣時，沒想到解決方式竟然是提醒說更新前，記得做快照…，然後就教怎麼把網卡設定檔做備份，等遇到這問題時，就有解了。看完瞬間晴天霹靂，後來不死心的試各種方式，結果發現無法將IP寫入設定檔，加上前面KB的說明，想想應該是網卡設定檔異常。
隨即試著幫Appliance環境新增一張VMXNET3的網卡，重開之後仍無效，再上網查詢”failed to read network interface files for eth1″的處理方式，又找到另外一篇KB，依照下列步驟重新設定新的網卡：
::Copy the /etc/sysconfig/networking/devices/ifcfg-eth0 to /etc/sysconfig/networking/devices/ifcfg-eth1 file by running this command: cp /etc/sysconfig/networking/devices/ifcfg-eth0 /etc/sysconfig/networking/devices/ifcfg-eth1 ::Open the ifcfg-eth1 file using a text editor. ::Delete the vi /etc/sysconfig/networking/devices/ifcfg-eth1 command as it is specific to the vi editor. The user can choose to use any editor for this purpose. ::Edit the file adding values for your network. ::For example: DEVICE=eth1 BOOTPROTO='static' STARTMODE='auto' TYPE=Ethernet USERCONTROL='no' IPADDR='192.168.1.117' NETMASK='255.255.255.0' BROADCAST='192.168.1.255' ::Create a symlink for this file in /etc/sysconfig/network by running this command: ln -s /etc/sysconfig/networking/devices/ifcfg-eth1 /etc/sysconfig/network/ifcfg-eth1 ::Restart the networking service to activate the new setup, by running this command: service network restart
做完之後，Appliance總算復活，看起來是更新之後，不知道為啥他要去不存在的eth1 (原本是eth0)，因此只要新增網卡，再把相關設定好，即可解決。
