High availability of daemon processes Fabric OS v6.1.0 and later supports automatic restart of non-critical daemons. Starting these non-critical daemons is automatic; you cannot configure the startup process. The following sequence of events occurs when a non-critical daemon fails: 1. A RASlog and AUDIT event message is logged. 2. The daemon is automatically started again. 3. If the restart is successful, then another message is sent to RASlog and AUDIT reporting the successful restart status. 4. If the restart fails, another message is sent to RASlog and no further attempts are made to restart the daemon. Schedule downtime and reboot the switch at your convenience. The following table lists the daemons that are considered non-critical and are automatically restarted on failure. TABLE 7 Daemons that are automatically restarted Daemon Description arrd cald raslogd rpcd snmpd traced trafd webd weblinkerd Asynchronous Response Router, which is used to send management data to hosts when the switch is accessed through the APIs (FA API or SMI-S).
