If your running Red Hat this might help-

The configuration file for cluster has to be correct (might have misspelled something) and there are rules that apply that need to be followed.

Hope that helps.

No, this cannot help.
Read the topic title :
It's not a RedHat cluster, it's an AIX cluster.
How did you create your cluster?
Do you have a disk connected to both computers? Did you create a concurrent volume group before creating the cluster? could you import the volume group on the second node ?
Obviously you have a lock problem, and this problem is probably coming from a hardware or a logical issue, so you should first fix the hardware things and check that your disk with a test filesystem can be imported and then varied on successfully on each system.
As usual in these kind of situations, check that you are able to manually do some things before asking HA/CMP to automatically do them for you :)
