網卡錯誤訊息：device eth1 does not seem to be present delaying initialization.

摘要:網卡錯誤訊息：device eth1 does not seem to be present delaying initialization.

IDC對雲端伺服器進行調整，開機後進去查看，結果發現網卡eth1沒有啟動。

重新啟動後，出現錯誤訊息：device eth1 does not seem to be present delaying initialization.

輸入ifconfig -a，發現沒有eth1，卻多了eth2，但也沒啟動。

輸入dmesg | grep -in eth

多了一行類似此類訊息：udev renamed network interface eth2 to eth1

註：因為我已經解決後關掉了，所以記憶中應該是上列訊息。

檢查/etc/udev/rules.d/70-persistent-net.rules

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="OLD MAC ADDRESS", ATTR{type}=="1",

KERNEL=="eth*", NAME="eth1"

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="OLD MAC ADDRESS", ATTR{type}=="1",

KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="NEW MAC ADDRESS", ATTR{type}=="1",

KERNEL=="eth*", NAME="eth2"

多了一個eth2，因此把eth2的MAC ADDRESS複製貼上到eth1上，並將eth2註解掉。

再至/etc/sysconfig/network-scripts/ifcfg-eth1

將eth2的MAC ADDRESS加入到HWADDR中。

然後再將伺服器重新開機後檢查，確認eth1已可正常啟動。
