If a system loses a network link to the cluster, other systems stop receiving heartbeats over the links from that system. LLT detects this and waits for 32 seconds before declaring the system lost a link.
See VCS performance consideration when a system fails.
You can modify the LLT peer inactive timeout value in the /etc/llttab
file.
For example, to specify 12 seconds:
set-timer peerinact:1200
