If a file named etc/sysconfig/network/ifcfg-eth-id-00:02:B3:DB:38:FE does not exist, do the following task:

■Create the file.

■If the file /etc/sysconfig/network/ifcfg-eth0 exists, then copy the contents of this file into etc/sysconfig/network/ifcfg-eth-id-00:02:B3:DB:38:FE.

Add the following to the end of the file named etc/sysconfig/network/ifcfg-eth-id-00:02:B3:DB:38:FE,

PERSISTENT_NAME=eth0

Perform the procedure for all the interfaces that the ifconfig -acommand displays.

To configure interfaces to be up before starting LLT

1For each network interface that you want LLT to use, find its MAC address by running the ifconfig command:

#ifconfig eth0

eth0 Link encap:Ethernet HWaddr 00:0C:0D:08:C4:32

Where eth0 is the sample network interface name. The output displays 00:0C:0D:08:C4:32 as the interface’s MAC address.

2Navigate to the config file in the /etc/sysconfig/network directory:

# cd /etc/sysconfig/network

3Open the config file in an editor.

4Append the string eth-id-macaddress to the MANDATORY_DEVICES list in the config file. Separate each address with a space, for example:

MANDATORY_DEVICES="eth-id-00:0C:0D:08:C4:31 eth-id-00:0C:0D:08:C4:32"

Setting up inter-system communication

When you install VCS using the installvcs program, to install and configure the entire cluster at one time, make sure that communication between systems exists. By default the installer uses ssh. You must grant root privileges for the system
