Preparing for a single node installation
You can use the installerprogram to installa clusteron a singlesystem foreither
of the two following purposes:
■ To prepare the single node cluster to join a larger cluster
■ To prepare the single node cluster to be a stand-alone single node cluster
When you prepare it to join a larger cluster, install it with LLT and GAB. For a
stand-alone cluster, you do not need to enable LLT and GAB.
For more information about LLT and GAB:

installing VCS using the product installer.

adding cluster node online, you have an option to proceed
without starting GAB and LLT.
Starting GAB and LLT is recommended.
