Verifying the configuration files
You can inspect the contents of the configuration files that were installed and
modified after a successful installation process. These files reflect the
configuration based on the information you supplied.
To verify the configuration files
1 Log in as superuser to any system in the cluster.
2 Set up your environment PATH variable.
# export PATH=$PATH:/sbin:/usr/sbin:/opt/VRTS/bin
Low Latency Transport configuration files
The following files are required by the VCS communication services for Low
Latency Transport (LLT).
/etc/llthosts
The file llthosts(4) is a database, containing one entry per system, that links
the LLT system ID (in the first column) with the LLT host name. This file is
identical on each system in the cluster.
For example, the file /etc/llthosts contains entries that resemble:
0 system01
1 system02
/etc/llttab
The file llttab(4) contains information that is derived during installation and
used by the utility lltconfig(1M). After installation, this file lists the network
links that correspond to the specific system.
For example, the file /etc/llttab contains entries that resemble:
set-node system01
set-cluster 100
link lan1 lan:1 - ether - -
link lan2 lan:2 - ether - -
The first line identifies the local system name. The second line identifies the
cluster (that is, the cluster ID you entered during installation). The next two
lines, beginning with the link command, identify the two network cards used
by the LLT protocol.
See the llttab(4) manual page.
The manual page describes the ordering of the directives in the llttab file.
