directory, by default. You can use a text editor, such as vi, or the more command to view the log file for historical information on your cluster.

It is always a good idea to review the syslog.log file on each of the nodes in the cluster when troubleshooting cluster problems.

This log provides information on the following:

•Commands executed and their outcome.

•Major cluster events which may, or may not, be errors.

•Cluster status information.

NOTE: Many other products running on HP-UX in addition to Serviceguard use the syslog.log file to save messages. The HP-UX System Administrator’s Guide provides additional information on using the system log.

Reviewing Object Manager Log Files

The Serviceguard Object Manager daemon cmomd logs messages to the file /var/opt/cmom/ cmomd.log. You can review these messages using the cmreadlog command, as follows:

cmreadlog /var/opt/cmom/cmomd.log

Messages from cmomd include information about the processes that request data from the Object Manager, including type of data, timestamp, etc.
