10.7.1 Collecting the log information in a cluster system

Pay attention to the following items when you collect the Performance Management log information in a cluster system:

• The common message log and trace log are output to the shared disk when Performance Management is used on a logical host.

  Log information before and after the failover is recorded in the same log file since the log file on the shared disk is inherited together with the system when a failover takes place.

• If Performance Management is used on a logical host, it is necessary to refer to the information from around the time when a failure occurs. For this reason, you need to extract the log information on both the executing node that stopped the processing due to the failover and the failover destination standby node.

For details on how to collect the log information output by Performance Management, see 17.6 Procedures for collecting data in the event of trouble.
