It repeats this message in syslog.log:
Mar 29 08:15:43 XXX cmcld: lan5 failed
Mar 29 08:15:49 XXX cmcld: lan5 recovered
Mar 29 08:43:38 XXX cmcld: lan5 failed
Mar 29 08:43:44 XXX cmcld: lan5 recovered
Mar 29 08:48:42 XXX cmcld: lan5 failed
Mar 29 08:48:48 XXX cmcld: lan5 recovered
Is this something to worry about?
Solved! Go to Solution.

Re: lan5 failed
This looks like some sort of 'discovery' like network flood. Too short to be a legitamate network overload, consistant enough to indicate an intentional network task.
If you get no diagnosis help from your network folks, you could try asking them to block some of the more common broadcasts from these switch ports and allow only what ServiceGuard requires.

Re: lan5 failed
You can verify what the setting is in your cluster by inspecting the cluster's binary file:
# cmviewconf | grep -i polling
network polling interval: 2.00 (seconds)
Since the recovery is 6 seconds after the failure, 3 check periods occur (on the default setting). The check is performed at the link-level, so transmission capability is being compromised. Best to get a network sniffer on the line and see what's happening.
