Log files

The PowerHA® SystemMirror® software writes the messages it generates to the system console and to several log files. Because each log file contains a different level of detail, system administrators can focus on different aspects of PowerHA SystemMirror processing by viewing different log files.

The main log files include:

• The /var/hacmp/adm/cluster.log file tracks cluster events.
• The /var/hacmp/log/hacmp.out file records the output generated by configuration scripts as they execute. Event summaries appear after the verbose output for events initiated by the Cluster Manager, making it easier to scan the hacmp.out file for important information. In addition, event summaries provide HTML links to the corresponding events within the hacmp.out file.
• The /var/hacmp/adm/history/cluster.mmddyyyy log file logs the daily cluster history.
• The /var/hacmp/clverify/clverify.log file contains the verbose messages output during verification. Cluster verification consists of a series of checks performed against various PowerHA SystemMirror configurations. Each check attempts to detect either a cluster consistency issue or an error. The messages output by the verification utility indicate where the error occurred (for example, the node, device, command, and so forth).

PowerHA SystemMirror allows you to view, redirect, save and change parameters of the log files, so you can tailor them to your particular needs.
