A Network Adapter's Name is Set to "rename <number>" after a Hardware Replacement or a Change in the Udev Network Rules (Doc ID 2095346.1)

Last updated on AUGUST 04, 2018

Applies to:

Linux OS - Version Enterprise Linux 3.0 and later
Oracle VM - Version 3.1.1 and later
Private Cloud Appliance - Version 1.0.1 and later
Exadata X6-8 Hardware - Version All Versions and later
Linux x86-64

Symptoms

After replacing a motherboard or a network card on Oracle Linux, Oracle VM or Oracle Private Cloud Appliance, the ethernet adapter(s)'s name will no longer be correct according to Network Interface naming scheme, listed as "rename<number>":

# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
2: em1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP qlen 1000
link/ether 98:90:96:ba:4b:74 brd ff:ff:ff:ff:ff:ff
3: rename3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 68:05:ca:2f:02:a0 brd ff:ff:ff:ff:ff:ff

 

The “ifconfig -a“ command (deprecated in latest Linux) also lists this interface as renameXX :

# ifconfig -a
[...]
rename3 Link encap:Ethernet HWaddr 68:05:CA:2F:02:A0
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:18 Memory:f7dc0000-f7de0000

 

Note: Manually altering the udev rules can also yield this kind of issue.
