The procedure to check which system tunables have been changed in the system since last boot is to run the 'lstuncfg -1 | grep -v DEFAULT' command. The lstuncfg command is used to display the current configuration of the system tunables. By using the '-1' option, the command will display the system tunables and whether they have been changed since the last system reboot. The 'grep -v DEFAULT' command will filter out the default values, allowing you to see only the tunables that have been changed. This command is available on IBM AIX v7 systems and is documented in the IBM AIX v7 Administrator Specialty Study Guide. For more information, please see the IBM documentation athttps://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds2/lstuncfg.htm.

AIX provides the syslog service to record console log messages. The syslog service is used to control the logging of system messages and can be used to record and store the log messages in different formats. The syslog service is enabled through the use of the alog and errdemon commands. The alog command is used to view the log messages that are stored in the /var/adm/syslog/syslog.log file, while the errdemon command is used to control the logging of system messages.

The superstrict mirror write consistency policy is the most reliable policy for achieving data consistency between mirrors in AIX V7.2. This policy will maintain the data consistency between mirrors by writing the data to both mirrors before the write operation is acknowledged as complete.
