Example Environment

The sample OpenVMS Cluster environment consists of two systems, BART and BARNEY.

Each node contains two network interfaces and six IP addresses.

Cluster-wide failover aliases: 16.112.249.241–16.112.249.244.

Node-specific IPs: BART (16.112.249.245, .246); BARNEY (16.112.249.247, .248). These addresses are also used as hardcoded interface IPs.

Cluster Layout:
