Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

To configure LLT and GAB on the new node

Edit the /etc/llthosts file on the existing nodes. Using vi or another text

editor, add the line for the new node to the file. The file resembles:

0 galaxy

1 nebula

2 saturn

Copy the /etc/llthosts file from one of the existing systems over to the

new system. The /etc/llthosts file must be identical on all nodes in the

cluster.

Create an /etc/llttab file on the new system. For example:

set-node saturn

set-cluster 101

link lan1 /dev/lan:1 - ether --

link lan2 /dev/lan:2 - ether --

Except for the first line that refers to the node, the file resembles the

/etc/llttab files on the existing nodes. The second line, the cluster ID, must

be the same as in the existing nodes.

Use vi or another text editor to create the file /etc/gabtab on the new node.

This file must contain a line that resembles the following example:

/sbin/gabconfig -c -nN

Where N represents the number of systems in the cluster. For a three-system

cluster, N would equal 3.

Edit the /etc/gabtab file on each of the existing systems, changing the

content to match the file on the new system.

Use vi or another text editor to create the file /etc/VRTSvcs/conf/sysname

on the new node. This file must contain the name of the new node added to

the cluster.

For example:

saturn
