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

Table 17-1
LLT configuration files (continued)
DescriptionFile
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 must be identical on each node
in the cluster. A mismatch of the contents of the file can cause indeterminate behavior in the
cluster.
For example, the file /etc/llthosts contains the entries that resemble:
0 galaxy
1 nebula
/etc/llthosts
The file llttab contains the information that is derived during installation and used by the
utility lltconfig(1M). After installation, this file lists the LLT 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 lan1 /dev/lan:1 - ether - -
link lan2 /dev/lan:2 - 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.
If you configured a low priority link under LLT, the file also includes a "link-lowpri" line.
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.
/etc/llttab
Table 17-2 lists the GAB configuration files and the information that these files
contain.
