Cluster Server 7.4.1 Configuration and Upgrade Guide - Linux

Setting up /etc/llttab for a manual installation

The /etc/llttab file must specify the system's ID number (or its node name), its cluster ID, and the network links that correspond to the system. In addition, the file can contain other directives. Refer also to the sample llttab file in /opt/VRTSllt.

Use vi or another editor to create the file /etc/llttab that contains the entries that resemble:

set-node node_name
set-cluster cluster_id
link eth1 eth-MAC_address - ether - -
link eth2 eth-MAC_address - ether - -

The first line must identify the system where the file exists. In the example, the value for set-node can be: sys1 or 0. The next line, beginning with the set-cluster command, identifies the cluster number, which must be a unique number when more than one cluster is configured on the same physical network connection. The next two lines, beginning with the link command, identify the two private network cards that the LLT protocol uses. The order of directives must be the same as in the sample llttab file in /opt/VRTSllt.

If you use different media speed for the private NICs, Veritas recommends that you configure the NICs with lesser speed as low-priority links to enhance LLT performance. For example:

Use vi or another editor to create the file /etc/llttab that contains the entries that resemble:

set-node node name
set-cluster cluster_id
link eth1 eth-MAC_address - ether - -
link eth2 eth-MAC_address - ether - -
link-lowpri eth3 eth-MAC_address - ether - -
