HAC logging
The High Availability controller (HAC) writes log records to the hacmsg.out file in the HAC working directory.
The log contains information about the following HAC operations:
warnings,
unrecoverable errors,
configuration-related information,
initialization-related information,
all input events,
HSB state changes,
user commands that cause changes in the system,
HAC state changes,
HAC mode changes (AUTOMATIC/ADMINISTRATIVE),
events that cause state changes in the system.
The HAC log file has a maximum size of 64 megabytes. When the size limit is reached, the hacmsg.out file is renamed to hacmsg.bak, and a new hacmsg.out file is created. The files contain at most 128 MB of the most recent logs.
