This script, written by Todd Mortensen (Veritas) in 2002, would use snoop on a network interface to detect what VCS cluster IDs it can find out on the network by looking at LLT packets (default packet header 0xCAFE). The script can be customized to serach for different packet headers, use different interfaces, grab a different number of packets, etc.

Best used on a public interface to detect what other cluster IDs are already in use for clusters using public heartbeats, so that you can avoid cluster ID duplication and conflict.

Note that this is a *.sh script, however it has been renamed to *.txt so that it can be easily posted on this forum. It has been tested with VCS 5.0 and works without issue.
