Issue

  • There are some cases that the network device ordering on Red Hat Enterprise Linux 6 during installation is different from that of Red Hat Enterprise Linux 5. The following is an example.

    ---------------------------------------
    MAC address        driver  RHEL5  RHEL6
    ---------------------------------------
    XX:YY:ZZ:00:00:00  e1000e  eth0   eth4
    XX:YY:ZZ:00:00:01  e1000e  eth1   eth5
    XX:YY:ZZ:00:01:00  e1000e  eth2   eth6
    XX:YY:ZZ:00:01:01  e1000e  eth3   eth7
    AA:BB:CC:00:00:00   bnx2   eth4   eth0
    AA:BB:CC:00:00:01   bnx2   eth5   eth1
    AA:BB:CC:00:01:00   bnx2   eth6   eth2
    AA:BB:CC:00:00:01   bnx2   eth7   eth3
    ---------------------------------------
    
  • This happens often when it has multiple network devices with different drivers.
