How to know what caused a failover in a 2-node SG

[Basheer_2]

Hello good morning,
we have 2 nodes in a sg and had failover to sec.

how do i know what caused the failover

[Mridul Shrivastava]

Need to check the syslog and /etc/cmcluster//.log on the primary server.

These logs will have messages about the MCSG and they will be helpful in identifying the issue.

[Sundar_7]

There are 10s of scenarios that will trigger the failover to the secondary.

# grep cmcld /var/adm/syslog/syslog.log

Post the output of above command.

Basheer,

You can check the syslog and the cluster log files.
/var/adm/syslog/syslog.log
/etc/cmcluster//.sh.log

Regards
Patrick

Also, don't forget to see if the primary node failed:

# uptime
# cat /etc/shutdownlog
# ls -al /var/adm/crash
