On Centos 6.2, while restarting the network service, I got the following error,

# service network restart
Shutting down interface eth0:  Device state: 3 (disconnected)
[  OK  ] Shutting down interface eth1:  Error: Device ‘eth1′ (/org/freedesktop/NetworkManager/Devices/1) disconnecting failed: This device is not active
[FAILED] Shutting down interface eth2:  Error: Device ‘eth2′ (/org/freedesktop/NetworkManager/Devices/2) disconnecting failed: This device is not active
[FAILED] Shutting down interface eth3:  Error: Device ‘eth3′ (/org/freedesktop/NetworkManager/Devices/3) disconnecting failed: This device is not active

Fix :

Please stop the NetworkManager and restart network service

[root@proxy network-scripts]# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ] [root@proxy network-scripts]# chkconfig NetworkManager off
[root@proxy network-scripts]# chkconfig network on
[root@proxy network-scripts]# service network restart
Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] [root@proxy network-scripts]#
