VCS performance consideration when a network link fails

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 16 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


After modifying the peer inactive timeout, you must unconfigure, then restart LLT before the change is implemented. To unconfigure LLT, type lltconfig -U. To restart LLT, type lltconfig -c.
