Assuming that there are no more unpropagated changes to your cluster environment I think you don't need to worry. Probably the easiest way to react to what you did would be: do nothing. HACMP has a function called lazy update which would detect the change in the FS during failover/takeover and can synchronise the cluster nodes without manual intervention. There are two possible drawbacks to keep in mind though. Firstly: the next takeover will take somewhat longer. Depending on your Resource Group that might or might not be a problem. Secondly: there is the possibility to overload the lazy update if there are several unpropagated changes. In such a case a takeover can fail. So when I said "do nothing" this also means: do not change anything in the cluster again before it is in sync again. Hopefully there weren't any unmanaged changes already before you extended the FS. After it is in sync use CSPOC only to configure the cluster's environment. It might be a good idea to edit the cluster node's herald message to inform root to not use standard AIX configuration commands.
Should you feel unhappy with this, there is also the possibility to update the LVM information on secondary nodes manually.
