System health check in AIX

- Use the errpt command to look at a summary error log report. Be on the lookout for recent additions to the      log. Use the errpt -a command to examine any suspicious detailed error log entries


Check disk space availability on the system with the df -k command. A full file system can cause a number of problems, so it is best to avoid the situation if at all possible. The two solutions to a full file system are to either

Check volume groups for stale partitions with the lsvg command. If stale partitions, logical volumes, or physical volumes are reported, try and repair the situation with the syncvg command.


Check system paging space with the lsps -s command. A system will not perform very well if it is low on paging space.
