Symptoms

The management network or storage network could be lost with the following scenarios.

Scenario1

• Add virtual machine role to the management network
• Then remove virtual machine role from the mgmt network

Then lost the management network.

[root@ovcacn07r1 ~]# ifconfig mgmt-int
mgmt-int: error fetching interface information: Device not found 

Scenario2

• Add virtual machine role to the storage network
• Then remove virtual machine role from the storage network

Then lost the storage network.

[root@ovcacn07r1 network-scripts]# ifconfig storage-int
storage-int: error fetching interface information: Device not found

But configuration files still available in the CN nodes.

[root@ovcacn07r1 network-scripts]# cat ifcfg-storage-int
