Section 2.7, "Red Hat Cluster Suite and SELinux"
•
Section 2.8, "Multicast Addresses"
•
Section 2.9, "Considerations for Using Conga"
•
Section 2.10, "General Configuration Considerations"

2.1. Compatible Hardware

Before configuring Red Hat Cluster software, make sure that your cluster uses appropriate hardware
(for example, supported fence devices, storage devices, and Fibre Channel switches). Refer to the
hardware configuration guidelines at
current hardware compatibility information.

2.2. Enabling IP Ports

Before deploying a Red Hat Cluster, you must enable certain IP ports on the cluster nodes and on
computers that run luci (the Conga user interface server). The following sections indentify the IP ports
to be enabled:
Section 2.2.1, "Enabling IP Ports on Cluster Nodes"
•
Section 2.2.2, "Enabling IP Ports on Computers That Run luci"
•

2.2.1. Enabling IP Ports on Cluster Nodes

To allow Red Hat Cluster nodes to communicate with each other, you must enable the IP ports
assigned to certain Red Hat Cluster components.
Nodes"
lists the IP port numbers, their respective protocols, and the components to which the port
numbers are assigned. At each cluster node, enable IP ports according to
on Red Hat Cluster Nodes".
Note
IPV6 is not supported for Cluster Suite in Red Hat Enterprise Linux 5.
