Perhaps I should use "interface" instead of "adapter".
interface "en0" and "en1" is backed by adapter "ent0" and "ent1".
Since both en0 and en1 are communication ports for PowerHA, when either en0 or en1 failure, the persistent IP and service IP should move to the other interface first.
In VIO environment, PCI hot plug is not available i.e. when you unplug the ethernet cable for ent0, in AIX it is still considered "up". You will only see an adapter failure at VIO, but not AIX.
In this case, IBM proposed using netmon.cf. But I failed following the this guildlines...

how did you simulate the interface down? hacmp will not react to ifconfig xxx down, at least in hacmp 5.4/5.5

That is what I want to know. I am using PowerHA 6.1 Sp5, VIOS 2.2
PCI Hot plug is not available for AIX with virtual ethernet. What I want to know is how will it detect an interface down? If it is not possible, how to make sure the IP will failover to another interface, when the interface is malfunction (e.g. unplugged ethernet cable in VIO)?
