Configuring LLT for a manual installation
VCS uses the Low Latency Transport (LLT) protocol for all cluster communications as a high-performance, low-latency replacement for the IP stack. LLT has two major functions.
It handles the following tasks:
Traffic distribution
Heartbeat traffic
To configure LLT, set up two files: /etc/llthosts and /etc/llttab on each node in the cluster.
