We use 2 commands to monitor / change parameters in Dell servers

3omconfig - Modifies the server details via specified parameters.
Examples :

1sudo omreport system summary | less
Display the Hardware logs
1sudo omreport system esmlog

Clearing the logs
1sudo omconfig system esmlog action=clear (Replace esmlog with alertlog or cmdlog, esmlog is the hardware log)
