[Linux-cluster] Listing openAIS parameters on RHEL Cluster Suite 5

The cluster.conf is attached.
I cannot test anything on the cluster anymore, as I no longer have access to it. I am out of this site and on another project.
Thanks and regards,

Where in cluster.conf do you have that statement ? Can you check that "cman_tool status" is showing the right value too ? it might be worth attaching your cluster.conf file.
