To remove a heartbeat link, perform the following command on each cluster node:
lltconfig -u (device tag)
For example:
# lltconfig -u qfe4
This command unconfigures the LLT link, but does not permanently remove the link from configuration files.
Upon reboot, or restart of LLT, the cluster node will use the link again.
To remove the link permanently from the configuration, on each cluster node modify the /etc/llttab file and remove the line for device "qfe4".
