Test the network connections. Temporarily assign network addresses and
use telnet or ping to verify communications.
LLT uses its own protocol, and does not useTCP/IP. So, you must ensurethat
the private network connections are used only for LLT communication and
not for TCP/IP traffic. To verifythis requirement, unplumb andunconfigure
any temporary IP addresses that are configured on the network interfaces.
The installvcs program configures the private network in the cluster during
installation.

Configuring SuSE network interfaces
Youmustperformadditional networkconfigurationonSuSE.You neednotperform
this procedure for thesystems thatrun SLES10 orlater. Bydefault, SLES10 uses
udev to achieve persistent interface names. Refer to the OS documentation for
information on configuring persistent interfaces on SLES 10.
In rare cases where RedHat does not automatically configure the network
interfaces, RedHat users may also have to perform the network configuration.
Review the following tasks that allow VCS to function properly:
■ VCS must be able to find the same network interface names across reboots.
■ VCS must have network interfaces up before LLT starts to run.
Symantec suggests the following steps for configuring network interfaces on
SUSE.
Note:You mustnot rebootthesystem betweenconfiguring thepersistent interface
names and configuring the interfaces to be up before starting LLT.
Note: The MAC address in the ifcfg-eth-id-mac file can be in uppercase or
lowercase.SUSE, and thereforethe Veritasproduct installer, ignoresthe filewith
lowercase MAC address if the file with uppercase MAC address is present.
