After upgrading from RHEL 6.4 to RHEL 6.6, the eth0 network interface is inaccessible and the server is offline. A review of /var/log/messages shows some of the following messages:
udev: renamed network interface eth0 to _eth0_
When I try to bring up eth0, I get the following error:
root@localhost>ifup eth0 bnx2 device eth0 does not seem to be present, delaying initialization.
root@localhost>ifconfig eth0 eth0: error fetching interface information: Device not found
