When doing several changes at a time on several systems you can use the IPMITool to execute commands from a file allowing you to script some of the iDRAC configurations. In my case I was wanting to change the username and password on the iDRACs of several systems.
Listed below are some examples:
Rename Root User, Set New Password and Clear the SEL
The above text file shows renaming the 'root' user, changing the password, listing the user to verify the change, and clearing the System Event Log. You could also do this with network settings as well.
