Removing permissions for communication
Make sure you completed the installation of VCS and the verification of disk
support for I/O fencing. If you used
rsh , remove the temporary rsh access
permissions that you set for the nodes and restore the connections to the public
network.
If the nodes use ssh for secure communications, and you temporarily removed
the connections to the public network, restore the connections.
