Take a look at the CLI user guide at the section Database Objects With Get and Set Commands from the Manuals & documentation for your Integrated Dell Remote Access Controller7/8 with Lifecycle Controller Version 2.30.30.30 
For years I have used the older style of racadm command syntax such as:  racadm getconfig -g cfgRacTuning -o cfgRacTuneWebserverEnable  The new style syntax as seen from help in the DRAC CLI is more like: racadm get idrac.webserver.enable  Is there a new PDF that details all the new get and set commands for racadm?
PDF for new style racadm syntax?
