4. Power off the switch.

High availability of daemon processes

Fabric OS 6.0 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, 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.
