Symantec 5 manual Setting up /etc/llthosts, Setting up /etc/llttab, LLT directives

Installing VCS on a single node 147

Adding a node to a single-node cluster

It handles the following tasks:

■Traffic distribution

■Heartbeat traffic

Configured as described in the following sections.

Setting up /etc/llthosts

The file llthosts(4M) is a database. This file contains one entry per system that links the LLT system ID (in the first column) with the LLT host name. You must create an identical file on each node in the cluster.

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

0north

1 south

Setting up /etc/llttab

The /etc/llttab file must specify the system’s ID number (or, its node name), 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.

See “LLT directives” on page 147.

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

set-node north set-cluster 2

link eth1 eth1 - ether - - link eth2 eth2 - ether - -

The first line must identify the system where the file exists. In the preceeding example, the value for set-nodecan be: north, 0, or the file name /etc/nodename. The file needs to contain the name of the system (north in this example) to use these choices. 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 file /opt/VRTSllt/sample-llttab.

LLT directives
