PRVE-0474 : Berkeley Packet Filter devices do not exist under

Met error PRVE-0474 when I performed a pre-installation check of grid infrastructure on both AIX nodes.

$ cd $ORACLE_HOME
$ ./runcluvfy.sh stage -pre crsinst -n primary01,primary02 -verbose
...
Verifying Berkeley Packet Filter devices /dev/bpf* existence and validation
check ...FAILED
primary01: PRVE-0474 : Berkeley Packet Filter devices do not exist under
              directory /dev on nodes "primary01".


primary02: PRVE-0474 : Berkeley Packet Filter devices do not exist under
              directory /dev on nodes "primary02".

Now what is Berkeley Packet Filter? The Berkeley Packet Filter (BPF) is a technology mostly used in analyzing network traffic, especially intrusion detection.

Let's check the actual files.

# ls -l /dev/bpf*
ls: 0653-341 The file /dev/bpf* does not exist.

Oh, there's none.

The solution is simple. Just dump traffic on network by tcpdump to initiate necessary filter devices.

# tcpdump -D
1.en0
2.en1
3.en2
4.lo0 [Loopback]

Then we check the filters again.

# ls -l /dev/bpf*
...
cr--------    1 root     system       12,  0 Mar 24 15:20 /dev/bpf0
cr--------    1 root     system       12,  1 Mar 24 15:20 /dev/bpf1
...

You can perform the pre-installation check again.
