Renaming the LLT and GAB Startup Files

Rename the LLT and GAB startup files. If you need to upgrade the single-system cluster to a multiple system cluster at a later time, you may need them.

Setting Up Configuration Files

This section describes setting up the configuration files main.cf and types.cf for your single-node VCS installation.

main.cf File

VCS requires the configuration file, main.cf, to exist in the directory /etc/VRTSvcs/conf/config. The main.cf configuration file has the following essential elements:

• An "include" statement that specifies the file, types.cf, which defines the VCS bundled agent resources
• The name of the cluster
• The name of the system that make up the single-system cluster

An example main.cf for a single-system cluster:

types.cf File

Note that the "include" statement in main.cf refers to a file named types.cf. This text file describes the VCS bundled agent resource type definitions. During new installations, the types.cf file is automatically copied in to the /etc/VRTSvcs/conf/config directory.

Editing the main.cf File

Refer to the VERITAS Cluster Server User's Guide for a full description of the main.cf file, how to edit it and verify it.

Verifying Single-Node Operation

1. Bring up VCS manually as a single-node cluster using hastart(1M) with the -onenode option:
     # hastart -onenode
2. Verify that the had and hashadow daemons are running in single-node mode:
     # ps -ef | grep ha
     root  285   1  0 14:49:31 ?  0:02 /opt/VRTSvcs/bin/had -onenode
     root  288   1  0 14:49:33 ?  0:00 /opt/VRTSvcs/bin/hashadow
