Sun Cluster 3.1 failover

Hi,
We have two sun SPARC server in Clustered (Sun Cluster 3.1). For some reason, System 1 failed over to System 2. Where can I find the logs which could tell me the reason for this failover?

Thanks

have a look at "scstat" and of course /var/adm/messages.

Humm,.. i looked in /var/adm/messages,.. but didn't find anything in there.

also check /var/cluster/logs,.. but those files very old

Scstat only tells the status of the cluster,..... (the cluster backup, working on two nodes, active active)

All loggin from the cluster is kept in the /var/adm/messages files, so if those files has been overwritten, then it is no way for you to see why the cluster did the failover unless your application did som logging of its self.

Actually, the /var/adm/messages file has some errors reported in it, but there is no info about failing over. I am assuming the log would say something like "server2 failed over".

I have asked the vendor to look into it and open a case with oracle.

Actually EMC rebooted on of our SPs. However, rebooting one SP just shifts all the LUNs on that SP to other SPs (Multipathing). It should have been transparent to the Cluster.

Well apparently, the Sun Cluster was fine. The issue was only at RAC level....
