Cause:
The problem is caused by broadcast parameter of network has been changed after AIX upgraded from 6.1 TL1 SP2 to SP4.The result of these change lead to the problem of broadcast ping.
If we don't specify a list host in NetworkHosts attribute to ping for a NIC resource, the monitor by default tests the NIC by pinging the broadcast address on the NIC. However, AIX 6.1 TL1 SP4 disables some network parameters for broadcast ping.
One of them has been identified by OS is bcastping. AIX 6.1 TL1 SP4 changed this parameter to bcastping = 0, which will disable the response to broadcast pings.
[root@arcrs6ka3cec config]# no -a
arpqsize = 12
arpt_killc = 20
arptab_bsiz = 7
arptab_nb = 149
bcastping = 0
-----------------
Solution:
Change bcastping to 1 to allow response to ICMP echo packets to the broadcast address by running the following command
# no -o bcastping=1
Change takes effect immediately. Change is effective until next boot. Permanent change is made by adding no command to /etc/rc.net
