Symantec Veritas 5 - Manual (Page 106)

The file llthosts is a database that contains one entry per system. This file
links the LLT system ID (in the first column) with the LLT host name. This file
is identical on each node in the cluster.
For example, the file /etc/llthosts contains the entries that resemble:
0 galaxy
1 nebula
■ The /etc/llttab file
The file llttab contains the information that is derived during installation
and used by the utility lltconfig(1M) . After installation, this file lists the
private network links that correspond to the specific system.
For example, the file /etc/llttab contains the entries that resemble:
set-node galaxy
set-cluster 2
link eth1 eth1 - ether - -
link eth2 eth2 - ether - -
If you use MAC address for the network interface, the file /etc/llttab contains
the entries that resemble:
set-node galaxy
set-cluster 2
link eth1 eth-00:04:23:AC:12:C4 - ether - -
link eth2 eth-00:04:23:AC:12:C5 - ether - -
The first line identifies the system. The second line identifies the cluster (that
is, the cluster ID you entered during installation). The next two lines begin
with the
link command. These lines identify the two network cards that the
LLT protocol uses.
Refer to the
llttab(4)
manual page for details about how the LLT
configuration may be modified. The manual page describes the ordering of
the directives in the
llttab
file.
■ The /etc/gabtab file
After you install VCS, the file /etc/gabtab contains a gabconfig(1) command
that configures the GAB driver for use.
The file /etc/gabtab contains a line that resembles:
/sbin/gabconfig -c -nN
The
-c
option configures the driver for use. The
-nN
specifies that the cluster
is not formed until at least N nodes are ready to form the cluster. By default,
N is the number of nodes in the cluster.
