The following list outlines the various log files and their locations used by Data ONTAP (7 mode). In addition, ONTAP also uses syslogd daemon to log system messages (and uses the config file /etc/syslog.conf)
You can see the content of those files using the “rdfile” command, e.g., rdfile /etc/log/messages
/etc/log/messages (symbolic link to /etc/messages)
/etc/log/backup and /etc/log/ndmpdlog
/etc/log/ftp.cmd and /etc/log/ftp.xfer
/etc/log/shelflog/shelflog_ata and /etc/log/shelflog_esh
/etc/log/acp/acplog_master and /etc/log/acplog
Hope it helps!
