RHEL 5 (2.6.18-8el5)

No, there aren't.

But service httpd was relocated to node01 while cluster member was specified

like 'clusvcadm -r httpd  -m node01'.

Now the service was on node01.
I did a test as follows:

I unplugged network cable of node01 for a while then plugged in again.
Service cman was terminated on node02 suddenly,
and it could not stop on node02.

logs on node02:

Any help would be greatly appreciated.
