rgmanager. For RHEL 5.1 and later, rgmanager does not use TCP or UDP sockets.

2.2.2. Enabling IP Ports on Computers That Run luci

To allow client computers to communicate with a computer that runs luci (the Conga user interface
server), and to allow a computer that runs luci to communicate with ricci in the cluster nodes, you
must enable the IP ports assigned to luci and ricci.
Runs luci"
lists the IP port numbers, their respective protocols, and the components to which the
port numbers are assigned. At each computer that runs luci, enable IP ports according to
"Enabled IP Ports on Red Hat Cluster
Note
If a cluster node is running luci, port 11111 should already have been enabled.

2.3. Configuring ACPI For Use with Integrated Fence
Devices
If your cluster uses integrated fence devices, you must configure ACPI (Advanced Configuration and
Power Interface) to ensure immediate and complete fencing.
Note
For the most current information about integrated fence devices supported by Red Hat
Cluster Suite, refer to
