Cluster Management and Administration

More details on how to configure HAView and on how to monitor your cluster 
with HAView can be found in Chapter 3, “Monitoring an HACMP cluster” in 
HACMP for AIX, Version 4.3: Administration Guide, SC23-4279.
8.1.3  Cluster Log Files 
HACMP for AIX writes the messages it generates to the system console and 
to several log files. Because each log file contains a different subset of the 
types of messages generated by HACMP for AIX, you can get different views 
of cluster status by viewing different log files. HACMP for AIX writes 
messages into the log files described below. See Chapter 2, “Examining 
Cluster Log Files”, in the 
HACMP for AIX, Version 4.3: Troubleshooting 
Guide, SC23-4280 for more information about these files.
8.1.3.1  /var/adm/cluster.log 
The
 
/var/adm/cluster.log file is the main HACMP for AIX log file. HACMP 
error messages and messages about HACMP for AIX-related events are 
appended to this log with the time and date when they occurred.
8.1.3.2  /tmp/hacmp.out
The /tmp/hacmp.out
 
file records the output generated by the configuration 
and startup scripts as they execute. This information supplements and 
expands upon the information in the /var/adm/cluster.log file. To receive 
verbose output, the Debug Level run-time parameter should be set to 
high, 
which is the default. 
8.1.3.3  /usr/sbin/cluster/history/cluster.
mmdd
The /usr/sbin/cluster/history/cluster.mmdd
 
file contains timestamped, 
formatted messages generated by HACMP for AIX scripts. The system 
creates a cluster history file whenever cluster events occur, identifying each 
file by the file name extension 
mmdd, where mm indicates the month and dd 
indicates the day.
While it is more likely that you will use these files during troubleshooting, you 
should occasionally look at them to get a more detailed picture of the activity 
within a cluster.
8.1.3.4  System Error Log 
The system error log file contains timestamped, formatted messages from all 
AIX subsystems, including HACMP for AIX scripts and daemons. Cluster 
events are logged as operator messages (error id: AA8AB241) in the system 
error log.
