Enterprise High Availability (SLE-HA) extensions in order to operate properly. Additional product details regarding

2.4.1 Prerequisites for Cluster Setup
Before you create a cluster, you need to perform the following tasks to ensure that all of the necessary modules and
settings are pre-configured.
2.4.1.1 Prepare the Operating System
Perform the following steps to prepare the operating system:
1. Make sure that all of the maintenance updates for the SLES 11 Service Pack 2/3 are installed.
2. Install the SLE-HA extension by performing the following steps.
a. Download the SLE-HA Extension iso to each node.
b. To install this SLE-HA add-on, start YaST and select Software > Add-On Products.
c. Select the local ISO image, and then enter the path to ISO Image.
d. From the filter list, select Patterns, and activate the High Availability pattern in the pattern list.
e. Click Accept to start installing the packages.
f. Install the High Availability pattern on node 2 that is part of the cluster.
2.4.1.2 Configure Network Settings
Each node should have two Ethernet ports, with one (em1) connected to the network switch, and another (em2)
connected to the em2 ethernet port on the other node.
Perform the following steps to configure network settings:
1. Perform the following steps to assign the static IP addresses:
a. In each node, set up the static IP address for both em1 and em2 ethernet ports by selecting Application >
yast > Network settings.
b. Select the ethernet port em1, and then select Edit.
c. Select the statically assigned IP address, input the IP Address/ Subnet Mask / Hostname, and then confirm the
changes.
d. Repeat steps b and c for ethernet port em2.
2. You need to open the following ports for each node in the firewall for communication of cluster services between
nodes:
— TCP Ports – 30865, 5560, 7630, 21064
— UDP Port – 5405
3. Create the file /etc/sysconfig/network/routes, and enter the following text:
default YOUR_GATEWAY_IPADDRESS - -
4. Edit the file /etc/resolv.conf to change the DNS IP address to the IP address of the DNS server in your network in
the following format:
nameserver YOUR_DNS_IPADDRESS
Alternatively, you can set the DNS and Default gateway in the Network Settings screen Global Options tab,
Host/DNS tab, or Routing tab, as shown in the following figures.
