6. After you set up both servers, run the ifconfig command to check the

network interface information.

Red Hat Enterprise Linux 6.1

To set up the Ethernet network on Red Hat Enterprise Linux 6.1, complete the

following steps:

1. As root, open a terminal and run the following commands:

– chkconfig NetworkManager off

– service NetworkManager stop

2. Open a terminal and run system-config-network, and follow the wizard to

configure the Ethernet network.

3. Run the following command in a terminal to restart network service and check

the Ethernet interface information:

service network restart

ifconfig

3.2.7 Step 7: Setting up the interconnect network

An interconnect network is required to install the DB2 pureScale feature on a

Linux distribution. Cluster CFs support multiple cluster interconnects to help DB2

pureScale environments with high availability and scalability. This section

explains how to set up the interconnect network with one cluster interconnect

adapter port for each CF.

The DB2 pureScale feature supports multiple high speed interconnect networks

in one cluster. If you want to set up multiple high speed networks in one cluster,

visit the DB2 Information Center for more information.

Important: You have finished the Ethernet network setup on Red Hat

Enterprise Linux 5.6. Proceed to 3.2.7, “Step 7: Setting up the interconnect

network” on page 132 to continue.

Attention: Perform this task on all servers in the cluster.

Important: You have finished setting up the Ethernet network on the Red Hat

Enterprise Linux 6.1 system and can continue to the next section.

network, see “Setting up an InfiniBand network on SUSE Linux Enterprise

Server 11” on page 133.

“Setting up the 10 GbE network on SUSE Linux Enterprise Server 11” on

page 138.

򐂰 If you are using Red Hat Enterprise Linux 5.6 with an InfiniBand network, see

“Setting up the InfiniBand network on Red Hat Enterprise Linux 5.6” on

page 140.

page 143.

Setting up an InfiniBand network on SUSE Linux Enterprise

Server 11

To install the InfiniBand (OFED) driver on SUSE Linux Enterprise Server 11, you

must install several rpm packages. You also must configure the SUSE updates

repository for your version of SUSE Linux Enterprise Server.

Important: On Linux and AIX, ensure that you configure a default gateway on

all hosts that are part of the DB2 pureScale cluster.

Host First node Second node

Interconnect IP address 192.168.100.151 192.168.100.152

Interconnect netmask 255.255.255.0 255.255.255.0

Important: Complete these steps on all servers in the cluster.

134 Delivering Continuity and Extreme Capacity with the IBM DB2 pureScale Feature

To set up the InfiniBand network on SUSE Linux Enterprise Server 11, complete

the following steps:

1. If you are using SUSE Linux Enterprise Server 11 SP1, install the following

packages from the updates repository. Contact your system administrator to

get a copy of these packages and use the rpm command to install the

packages. If you are using SUSE Linux Enterprise Server 11 SP2, these

packages are on the installation DVD.
