The agent starts rpc.lockd and rpc.statd, which are responsible to send notification after reading the nfs lock directory. The agent copies some records in nfs lock directory, which is used by the re-started lockd or statd daemons for notification.
The smsyncd daemon copies lock information from /var/statmon/sm to shared storage. The agent's online function copies the locks from shared storage to /var/statmon/sm.
