The individual logs are limited to a maximum size and are removed after they reach a certain age, or are overwritten by newer versions. Also for all the resource groups on the Active node please specify the passive node as the next node in the priority to take over in the event of failure of active node.


The following sections describe the types of messages output by the PowerHA SystemMirror software and the log files into which the system writes these messages. Using cluster log files.

My survival notes : Problem determination PowerHA / HACMP

Understanding the system error log The PowerHA SystemMirror software logs messages to the system error log whenever a daemon generates a state message. Reviewing cluster message log files The PowerHA SystemMirror software writes the messages it generates to the system console and to several log files.


The event summaries included in this log make it easier to see quickly what events have occurred recently guidde the cluster.

Each copy is identified by a number appended to the file name. Each log file contains a different subset of messages generated by the PowerHA SystemMirror software.

When viewed as a group, the log files provide a detailed view of all cluster activity. The verification process does not allow the IP addresses to be in same subnet and cluster will not start. Resource group handling has been enhanced in recent releases and the hacmp. Then read back through the log file to the first message relating to that problem.
