iDRAC.Info.Name is a read only attribute and you can not modify the value of it. "User Interface Title Bar Information" will not change iDRAC Name. It will change the information which need to be shown in browser while using iDRAC. To change this in racadm you need to use attribute "iDRAC.WebServer.TitleBarOption". You can refer below link for more details on this [URL]  
Hi, I have quite a few PowerEdge servers and I need to set their iDrac Name from CLI but here is what I get this behavior : # ssh server 'racadm set iDRAC.Info.Name iDRAC-$HOSTNAME'root[NAME]'s password:ERROR: The specified object is READ ONLY and cannot be modified. Changing the Name from the iDrac v2.83.83.83 Web interface works fine in the "Overview->iDrac Settings->User Interface Title Bar Information" What is the correct "racadm" command to do this ?
Cannot change the iDrac Name from racadm
